  The OLT according to the embodiment improves the availability of the OLT by separating a part of allocation functions such as DBA, DWA, and DWBA among the functions included in the PON access control function into an instruction unit.

(Embodiment 1)
The embodiment described below is an OLT having a DBA function, and the OLT includes an implementation unit and an instruction unit. The implementation unit mainly performs simple processing. For example, the same destination is repeatedly assigned with a predetermined bandwidth or a predetermined bandwidth setting. The instructing unit instructs the implementing unit so that the allocation of the implementing unit approaches a desired state according to a service policy that differs depending on a communication carrier or service. For example, the allocation information in the implementation unit is detected, and according to the difference between the detection result and the desired allocation, the allocation of the allocation in the implementation unit, the allocation result, the allocation history, or the data continuity, continuity history, request, or The request history is detected, and one of the following (a) to (e) is instructed to the execution unit so that the detection result approaches the desired allocation.
(A) Allocation suppression or priority allocation to at least a part of allocation targets (Embodiment 1.1)
(B) Change of bandwidth setting (Embodiment 1.2)
(C) Allocation (Embodiment 1.3)
(D) Order of allocation (embodiment 1.4)
(E) Allocation / allocation setting switching (Embodiment 1.5)

  In the OLT according to the embodiment, since the instruction unit instructs the allocation in the execution unit to approach a desired allocation, the determination unit and the determination algorithm and policy of the allocation process without changing at least the determination algorithm and software related to the allocation in the execution unit Can be changed. In the present embodiment, as long as there is no need to change, the time elapses and allocation is continued with the same predetermined bandwidth or bandwidth setting for each destination. “Continue” is continued unless an instruction to change is received. Note that the minimum continuous time is equal to or greater than the sum of the time required for the execution unit to respond to an instruction, the time required for creating an instruction in the instruction unit, and the communication time of the instruction unit and the execution unit. It is desirable that the instruction from the instruction unit and the response of the implementation unit are the same, or have a period and relationship that is proportional to an integer multiple or a fraction of an integer, but a process that continuously detects at least a part of the history such as exponential average is used. For example, the cycles may be asynchronous even if they are not in a multiple relationship. The period may be a period related to the allocation of DBA, DWA, DWBA, or the like, or may be a period in which the allocation to the allocation target for which allocation is at least requested or predicted to be requested is completed.

  The allocation information in the implementation unit includes at least one of the allocation in the implementation unit, the allocation result, the allocation history, the data continuity or continuity history associated with the allocation, the request, or the request history. “Request” refers to a request for an upstream bandwidth / transmission time or a prediction of it in a declaration of an ONU. Requests and request histories may be partly or entirely processed or held by the execution unit, part or all of the request and request history may be processed or held by the instruction unit, or part or all of the request history may be processed by the execution unit and the instruction unit. May be processed and held independently, or part or all may be processed and held by the implementation unit and the instruction unit and handed over to the other, or part or all may be transferred to the other than the implementation unit and the instruction unit And may be processed and held and passed to at least one of the implementation unit and the instruction unit. For the request, the request itself may be used, or the prediction predicted from the allocation or allocation result or allocation history or data continuity or continuity history or request or request history may be used, or both may be used in combination. At least a part of the request prediction may be performed by the implementation unit or the implementation unit or other, and at the place of the request, the allocation or allocation result or allocation history or data continuity or continuity history or request or request history, etc. It is desirable to receive information necessary for the prediction of Data continuity may be detected by any of the implementation unit, the instruction unit, and other parts such as SW12 and SW13, the proxy unit 15, which will be described later, where the main signal is conducted, and the higher-level device of the main signal or control signal network. . The conduction history, which is the conduction amount processing and the data conduction history, includes the execution unit, the instruction unit, and other locations such as SW12, SW13, the proxy unit 15, which will be described later in which the main signal is conducted, You may process and hold | maintain the detection result of conduction | electrical_connection amount, such as a controller, in the place which processes and hold | maintains. In the case of implementation by an operation system, a controller, or the like, traffic information input to the operation system, the controller, or the like may be processed and held by, for example, SNMP (Simple Network Management Protocol), NETCONF (Network Configuration Protocol), or OpenFlow. Similar to the request or request history, part or all of the continuity or continuation history or allocation or allocation result or allocation history may be used by the implementation unit, the instruction unit, any other or all of them, or passed to each other. .

Although it is mainly considered to make a prediction based on a request received by the implementation unit, a request predicted by the implementation unit based on a request received by the implementation unit, and a predicted reception, the following configuration may be used.
A configuration in which a request is terminated and used at an instruction unit. The implementation unit performs allocation without request, and the request is used only by the instruction unit.
A configuration in which the request is terminated at the instruction unit, and the request or the request prediction is transferred to the execution unit with or without use at the instruction unit.
A configuration in which requests are terminated at both the implementation unit and the instruction unit and used independently.
A configuration in which the request is terminated at the implementation department and used by the implementation department.
A configuration in which the request is terminated at the implementation unit, and the request or the request prediction is transferred to the instruction unit with or without use at the implementation unit.
A configuration in which the request is terminated by the instruction unit and the request history is also held by the instruction unit.
A configuration in which the request is terminated by the instruction unit, and the request history is held by the execution unit, either using or not using the instruction unit.
A configuration in which the request is terminated at both the implementation unit and the instruction unit, and the request history is held at both.
A configuration in which the request is terminated at the execution unit and the request history is held at the execution unit.
A configuration in which the request is terminated in the execution unit and the request history is held in the instruction unit.

Embodiment 1.1
In the present embodiment, the band allocation in time division multiplexing in one wavelength of TWDM-PON is exemplified, but time division multiplexing, wavelength division multiplexing, core division multiplexing, core division multiplexing, mode division multiplexing or code You may allocate by at least 1 combination of other division multiplexing, such as division multiplexing or (orthogonal) frequency division multiplexing. In this case, the same applies if the wavelength of the division multiplexing, the core wire, the core, the mode, the code or the sum of other division multiplexing such as (orthogonal) frequency is assigned. For example, if 4 wavelengths of 10 Gbit / s / λ are used, 40 Gbit / s is obtained, and if 10 Gbit / s and 20 Gbit / s cores are provided one by one, 30 Gbit / s is provided, and 4 wavelengths of 10 Gbit / s / λ are provided. If it is a two-core wire, 80 Gbit / s is allocated, and the instruction may be a combination of the allocated ones. Here, the allocation is either the allocation band or wavelength or the core or mode or code or the code or (orthogonal) frequency or the allocation band or wavelength or the core or mode or code or depending on the object to be allocated. Any of the allocated bands for each (orthogonal) frequency or the total allocated band may be used.

  The implementation unit of the present embodiment continues the assignment to the same destination with a predetermined band or wavelength or core wire or core or mode or code or (orthogonal) frequency or at least any combination thereof. The instruction unit of the present embodiment detects the allocation or allocation result or allocation history or data continuity history or request or request history associated with the allocation of the implementation unit, and determines the difference between the detection result of a predetermined period and the desired allocation. In response to this, the execution unit is instructed to perform allocation suppression or priority allocation for at least a part of the allocation target.

  The predetermined bandwidth is, on average, an allocation target (for example, ONU or ONU queue or ONU class buffer or Alloc-ID (Allocation Identifier) or T-CONT (Transmission Container) or LLID (Logical Link ID (IDentifier)). ) Etc.) If there is a fixed bandwidth setting for each, the lower limit is set, and if there is a maximum bandwidth setting, or if there is a total bandwidth available for multiple allocation targets, or if there are both, the lower limit is set as the upper limit. Is desirable.

  The predetermined bandwidth is a single or plural BWMap form, an allocation time for each allocation unit such as T-CONT, Alloc-ID, and LLID, a combination of start time and allocation time, T-CONT, Alloc-ID, LLID, etc. The bandwidth may be a combination of allocation time and allocation order for each allocation unit.

  The predetermined period is preferably longer than the time required for the execution unit to change the predetermined band upon receiving an instruction from the instruction unit. For example, it is several to several tens of times and is the time required for multiple changes. It is desirable that the time is such that the user does not detect a difference from the desired assignment. For example, it is desirable that the time unit for measuring the bandwidth is, for example, 1 second or less.

  The allocation of the implementation department or the result of assignment is the OAM or backboard, which is a report from the implementation department or the holding information for reporting to a higher system on the control side such as a measurement or operation system at any location or the history of past instructions. It is input from the history of instructions input or held by the instruction unit via the internal wiring, the main signal wiring, the dedicated wiring, the operation system, the controller, the control unit, or the like. The history may be accumulated by other than the instruction unit.

  The allocation history of the predetermined period is, for example, an exponential average, a moving average, an average in which the history is reset at a predetermined interval, and a history obtained by performing other statistical processing.

  Data continuity or continuity history associated with allocation is measured at any point, such as a report from the implementation department or the route of the main signal, or retained information for reporting to the host system, such as internal wiring, backboard, OAM, and main signal. Input via a route such as a line, dedicated wiring, operation system, controller or control unit. The history may be accumulated by other than the instruction unit.

  Requests or request histories are either entered directly from the ONU or a copy of the declaration and terminated at any point or terminated at any point, and the internal wiring, backboard, OAM, main signal line, dedicated wiring or operation system Or use of the allocated bandwidth via the path of the controller, controller, etc. (if there is an unused portion of the allocation, the used portion is requested, if there is no unused allocation (if it is all used), the request more than the allocation) Internal wiring, backboard, OAM, main signal line, dedicated wiring, operation system and controller for reporting from the implementation department, holding information for measurement at any location or reporting to the host system, or past instruction history Or via a route such as a control unit, or from a history of instructions held by the instruction unit. The history may be accumulated by other than the instruction unit.

  The request or request history can be estimated based on the input allocation or allocation history, data continuity or continuity history, allocation result, request or request history, and a future request or band that should have been allocated but not allocated. Good. The prediction may be performed by a statistical process such as a linear function, a quadratic function, an exponential average, or a moving average, or an RTT (Round Trip) set according to a past request, a result of allocation use, a distance from the server, or the like. Prediction) based on behavior such as TCP (Transmission Control Protocol) based on (Time), etc., and if there is no unused allocation, it may be predicted as guaranteed bandwidth setting, and if there is no unused allocation, guaranteed bandwidth setting Is the non-zero or guaranteed bandwidth setting minus the fixed bandwidth setting is non-zero, there is no unused allocation, or the guaranteed bandwidth setting exceeds the guaranteed bandwidth setting and the requested bandwidth is set to the guaranteed bandwidth setting or guaranteed bandwidth setting. The bandwidth may be estimated according to the value obtained by subtracting the fixed bandwidth setting from, and if there is no unused allocation, there is no unused allocation or the guaranteed bandwidth setting is exceeded. Band ratably best effort bandwidth of some assignment target may be predicted. Moreover, you may predict combining a some prediction method.

  The desired allocation depends on a predetermined ratio up to the allocation target with the request, up to the bandwidth obtained by adding the bandwidth for detecting the deviation from the predicted value of the request or the request or the predicted value of the request or the request. The band is sufficient. The predetermined ratio is, for example, a ratio of a guaranteed band setting or a value obtained by subtracting the fixed band setting from the guaranteed band setting. The predetermined band is for each wavelength, for each code, for each carrier frequency, for each core line, for each core, for each mode, for each code, for each (orthogonal) frequency, or for a combination of at least a part thereof, and for corresponding TRx (Transmiter and (Receiver), Tx (Transmitter), Rx (Receiver) unit, multiple wavelengths, code, carrier frequency, core, core, mode, code, or (orthogonal) frequency It may be set in units of OSU in which TRx, Tx, and Rx are bundled, such as at least some combinations, or in units of SW (Switch) in the OSU, or a plurality of wavelengths, codes, carrier frequencies, cores, cores, or modes Every or every code or every (orthogonal) frequency or a combination of at least some of them May be set in units of SW in which TRx, Tx, Rx, or OSU are bundled, or may be set in units of allocation targets that share the bandwidth of the higher-level device. Desired allocation is desirably set to the maximum bandwidth setting for each allocation unit as an upper limit, and if there is a total bandwidth setting as TRx, Tx, Rx, or a bundle of them, it is desirable to limit it.

The method of making the allocation for a predetermined period close to the desired allocation is arbitrary, and the following can be exemplified.
The implementation unit continues the allocation with a predetermined setting or bandwidth. The instructing unit has no allocation suppression or priority allocation stop or allocation suppression or priority allocation for allocation objects whose allocation exceeds the desired value, and priority allocation or allocation suppression stop or It indicates at least one of neither allocation suppression nor priority allocation. Here, instruct the priority allocation, allocation suppression, priority allocation stop, or allocation suppression stop when the pre-instruction is in the opposite state, or if it is over, indicate it on the insufficient side, and if it is insufficient, specify it on the excess side In this case, the side does not need to give an instruction. The bandwidth of allocation suppression and priority allocation may be explicitly instructed from the instruction unit, or some of the granularity may be instructed at a predetermined granularity, the instruction unit only allocates suppression, priority allocation only, It may be instructed that only allocation suppression and priority allocation, allocation suppression and priority allocation, neither allocation suppression nor priority allocation, allocation suppression stop and priority allocation stop, etc. Further, the suppression may be performed by completely suppressing the allocation of the allocation target and may be zero, and the priority may be allocated to the allocation target for all allocatable bandwidths. If the allocation target is ONU 1 to 3, the instruction to the execution unit is, for example, giving a mark only to the allocation suppression target, for example, “1”, and leaving no marking outside the allocation suppression target, for example, “0”. If only ONU1 is inhibited, an instruction is given corresponding to (ONU1, ONU2, ONU3) = (1, 0, 0). If only the priority allocation target is given a mark, for example, “1”, and if it is not the allocation suppression target, there is no mark, for example, “0” is left. If only ONU 1 is suppressed, (ONU1, ONU2, ONU3) = (1, 0, 0) are instructed. For example, “1” and “2” are assigned only to the priority allocation and allocation suppression targets, respectively, and there is no mark outside the allocation suppression target, for example, “0”. ONU1 and ONU2 are priority and suppression, respectively. If there is, an instruction is given corresponding to (ONU1, ONU2, ONU3) = (1, 2, 0). You may instruct | indicate by the priority or suppression target ONU number. Moreover, not only priority or suppression, but the capacity itself to be prioritized or suppressed, or a band or a set band may be listed. For example, ONU1 may be instructed corresponding to (ONU1, ONU2, ONU3) = (20, −10, 0), with ONU1 corresponding to priority 20 Mbit / s and ONU2 corresponding to inhibition 10 Mbit / s.

  As an example of flexible allocation, when the allocation ratio of the execution unit is equal to ONU 1 to 3 and the desired allocation ratio is 1: 2: 3, for example, the instruction unit sets the ONU ratio to the ONU ratio. Only the ratio of the period divided by the sum is given full priority, and the other periods are completely deterred. An allocation ratio of 1: 2: 3 can be obtained by combining complete priority and complete suppression so that the ratio of complete priority is 1/6, 2/6, and 3/6 in ONUs 1, 2, and 3, respectively.

An example of priority assignment and assignment suppression values set in the execution unit or instructed from the instruction unit is shown.
A single or multiple priority period preferential allocation is instructed so that the difference is resolved to an allocation target having a low allocation history for a predetermined period from a predicted allocation with a request or a desired allocation.
A single or multiple priority period preferential allocation is instructed so that the difference is resolved to a target to be allocated with a low allocation history for a predetermined period from a desired allocation or a predicted allocation with a request.

The allocation of one or a plurality of predetermined periods is suppressed with a fixed band setting as a lower limit so that the difference is resolved to the allocation target having a high allocation history for a predetermined period from the predicted allocation with the request or the request allocation.
A single or a plurality of predetermined period allocations are suppressed so as to eliminate the difference between allocations with a high allocation history for a predetermined period from a requested allocation or a requested allocation.
Priority allocation or deterrence so that the guaranteed bandwidth setting or fixed bandwidth setting of the allocation target is set to the allocation target having a high or low allocation history for a predetermined period from the predicted allocation with the request or the desired allocation.
-Predicted to be requested or requested and allocated to the allocation target with a high or low allocation history for a predetermined period from the desired allocation to the guaranteed bandwidth setting of the allocation target non-guaranteed allocated bandwidth or best effort bandwidth or its predicted value Accordingly, priority allocation or allocation suppression is performed for a band that is less than the allocated band.
-Preferential allocation or allocation suppression is performed so that a guaranteed bandwidth setting or a fixed bandwidth setting of the allocation target is set to the allocation target of the prediction of no request or no request.
-Allocation suppression or priority allocation is exemplified by an instruction to the allocation itself, but requests are increased / decreased, multiplied / divided at a predetermined ratio, and when the execution unit holds the history, the history is increased / decreased / divided.

  Transmission from the instruction unit to the implementation unit may be performed by giving an identifier such as a predetermined bit string so as to be distinguished from other information, may be transmitted in the form of Embedded OAM, or OAM Frame, MPCP (Multi Point Control Protocol) frame, predetermined VID (Virtual Local Area Network (VLAN) Identifier), MAC address, TOS / COS (Type of Service / Class of VPI / Class of VPI) Encapsulates and exchanges frames and cells that can be identified by Path Identification and VCI (Virtual Channel Identification) The instruction unit has a function of giving an identifier, encapsulation, and communication through a predetermined communication path so that the processing unit can be identified, and the processing unit can identify the identifier, decapsulate, and communicate through a predetermined communication path. The same applies to the input / output from the processing unit to the instruction unit, and the function to process and input to the instruction unit so that it can be received unless the instruction unit directly terminates the declaration from the ONU. Prepare for the route of declarations.

(Embodiment 1.2)
The implementation unit of the present embodiment continues the assignment to the same destination by setting a predetermined band, wavelength, core, core, mode, code, (orthogonal) frequency, or at least any combination thereof. The instruction unit according to the present embodiment instructs the implementation unit to change the bandwidth setting according to the difference between the detection result of the predetermined period and the desired allocation.

The method of making the allocation for a predetermined period close to the desired allocation is arbitrary, and the following can be exemplified.
The implementation unit continues the allocation with the predetermined setting. The instructing unit instructs the execution unit to decrease the set value for an allocation target whose allocation exceeds a desired value and to increase the set value for an insufficient allocation target. The set value may be instructed explicitly from the instructing unit, may be instructed at a predetermined granularity by some of the granularity, etc., and the instructing unit instructs to increase / decrease the set value and return to the initial setting. May be. The instruction to the execution unit is that the allocation object is set to some or all specific values such as ON_1 to ONU3, fixed band, guaranteed band, maximum band setting values P_FXBi, P_GUBi, P_MABi (i = 1 to 3), etc. A corresponding value may be instructed, an increase / decrease value of the corresponding set value may be instructed, or other set values may be instructed.

  As an example of flexible allocation, it is possible to provide a new service with an upper limit setting for the use bandwidth product for a predetermined period using an existing device, and to change the setting value when the instruction unit reaches the upper limit. This can be realized without changing the implementation unit.

The example of the value of the setting change instruct | indicated from an setting part or an instruction | indication part is shown.

The predetermined period may be for one or a plurality of BWMaps, may be for one or a plurality of DBA cycles, or may be a BWMap or DBA cycle other than an integer multiple as long as conversion is possible. . The timing for changing to the new allocation from the instruction unit of the implementation unit is preferably a timing at which the allocation is completed, but may be as soon as the new allocation arrives.

(Embodiment 1.4)
The implementation unit of the present embodiment continues the assignment to the same destination by setting a predetermined band, wavelength, core, core, mode, code, (orthogonal) frequency, or at least any combination thereof. The instruction unit according to the present embodiment instructs the execution unit of the order of allocation according to the difference between the detection result and the desired allocation.

The method of making the allocation for a predetermined period close to the desired allocation is arbitrary, and the following can be exemplified.
The implementation unit allocates a large band according to the order of allocation. For example, the assignment order is all assigned to the first assignment target, the request or request prediction is assigned to the first assignment target as an upper limit, and the remaining assignment is continued to the assignment target in the later order. In this example, the front order is the order in which the allocation is large, and the rear order is the order in which the allocation is small. The reverse case is the opposite. The allocation order of the implementation units may be the same every time unless an instruction is given from the instruction unit. The order may be changed so that the order is cycled up or down for every one or more assignments. The instructing unit is assigned in the order in which the allocation in the implementation unit is smaller with respect to the allocation target exceeding the desired allocation for the implementation unit, or in the order in which the allocation in the implementation unit is larger with respect to the allocation target that is insufficient. By instructing at least one of these, the desired allocation is approached. When the order is incremented or decremented or shifted for each allocation, it is desirable to arrange the allocation order in descending order of the difference between the detection result and the desired allocation. The allocation order is preferably changed every allocation cycle or every allocation cycle for the number of allocation targets whose request or request prediction is non-zero, but other than that when processing that continuously detects at least part of the history such as exponential average is used. Or the phase of the cycle may be shifted.

  As an example of flexible allocation, the allocation order of the implementation units is the same in the ONUs 1 to 3, for example 1-> 2-> 3-> 1->... When the allocation ratio is 1: 2: 3, for example, the instruction unit may set the order in which a large band is allocated based on the ONU ratio. For example, by setting 1-> 2-> 2-> 3-> 3-> 3-> ..., an allocation ratio of 1: 2: 3 can be obtained.

An example of an allocation order instructed from an instruction unit to an implementation unit that allocates a larger band in the forward order is shown. If it is an instruction to the execution unit that allocates a larger band in descending order, the front and rear in the following example are reversed.
・ The order of single or multiple predetermined period allocations is arranged more forward so that the difference is resolved to allocation targets with a low allocation history for a predetermined period from the predicted allocation with demand or requested allocation. .
The order of single or multiple predetermined period allocations is arranged more forward so that the difference is resolved to allocation targets having a low allocation history for a predetermined period from a predicted allocation with a request or a requested allocation.
・ Predicting with demand or with demand and assigning the order of single or multiple predetermined period allocation to allocation targets with high allocation history for a predetermined period from the desired allocation to the rear. .
The order of single or multiple predetermined period allocations is arranged further rearward so as to eliminate the difference between the allocation target having a high allocation history for a predetermined period from the predicted allocation with the request or the requested allocation.

Embodiment 1.5
The implementation unit of the present embodiment has a plurality of assignments or settings in advance in a predetermined band, wavelength, core, core, mode, code, (orthogonal) frequency, or at least one combination thereof at the same destination. Continue assignment or assignment in settings. In the case of assignment, for example, in the case of assignment and setting shown in Embodiment 1.3, for example, the setting shown in Embodiment 1.2 is used. The instruction unit according to the present embodiment instructs the execution unit to switch assignment or setting used by the execution unit according to the difference between the detection result of the predetermined period and the desired assignment.

The method of making the allocation for a predetermined period close to the desired allocation is arbitrary, and the following can be exemplified.
The implementation unit continues the allocation with the allocation or setting instructed by the instruction unit. The instructing unit instructs the execution unit to switch to allocation or setting that is at least one of allocation that is smaller for allocation targets that exceed allocation than desired and allocation for insufficient allocation targets. . The timing for changing to the new allocation or setting from the instruction unit of the implementation unit is the period related to the allocation of DBA, DWA, DWBA, etc., or the period when the allocation to the allocation target for which the allocation is predicted to be requested or requested is completed. It is desirable to synchronize at the time of completion of the assignment or to complete the assignment in the current setting, but it may be as soon as an instruction to switch to a new assignment or setting arrives. In particular, if a process that continuously detects at least a part of a history such as an exponential average is used, the periods may be asynchronous even if they are not in a multiple relationship.

  As an example of flexible allocation, it is possible to provide a new service with an upper limit setting for the bandwidth product for a predetermined period using an existing device. This can be realized without changing the implementation unit by instructing the implementation unit to change.

(Embodiment 2)
In this embodiment, time division multiplexing, wavelength division multiplexing, core division multiplexing, core division multiplexing, mode division multiplexing, code division multiplexing, or (orthogonal) frequency multiplexing are used in combination, and the wavelength to be used for allocation is used. Or it is exemplified by switching of a core line, a core, a mode, a code, a (orthogonal) frequency, or at least one of them (hereinafter referred to as a group). These are suitable for the case where switching of other division multiplexing is slow with respect to the allocation period of time division multiplexing and time division multiplexing and other division multiplexing are performed separately.

Also in this embodiment, the OLT includes a division multiplexing switching function, and the OLT includes an implementation unit and an instruction unit. The implementation unit mainly performs simple processing. For example, the same allocation object, for example, ONU, is allocated with a predetermined wavelength, core, core, mode, code, frequency, predetermined wavelength setting, core setting, core setting, mode setting, code setting, or frequency setting. The instructing unit instructs the implementing unit so that the processing result of the implementing unit approaches a desired allocation according to a service policy that varies depending on a communication carrier or service. For example, the allocation information in the implementation unit is detected, and the following is performed from the following (a) to (e) so that the allocation in the implementation unit approaches the desired allocation according to the difference between the detection result and the desired allocation. )
(A) Switching inhibition or priority switching for at least a part of the allocation target (Embodiment 2.1)
(B) Change of switching setting (embodiment 2.2)
(C) Switching (Embodiment 2.3)
(D) Switching order (Embodiment 2.4)
(E) Switching / switching of switching settings (Embodiment 2.5)

  Next, the wavelength, the wavelength, the core, the core, the mode, the code, the frequency, or at least any combination thereof will be exemplified by paying attention to the wavelength. This switching corresponds to DWA if it is a wavelength.

Embodiment 2.1
The implementation unit of the present embodiment switches the allocation target group according to a predetermined order. The predetermined order means, for example, that at least a part of allocation units simply changes a group sequentially or switches a group of at least a part of allocation units belonging to a light congestion or heavy congestion group that exceeds or falls below a predetermined threshold. It is the order to do. The instruction unit of the present embodiment detects the allocation or allocation result or allocation history or data continuity history or request or request history associated with the allocation of the implementation unit, and determines the difference between the detection result of a predetermined period and the desired allocation. Accordingly, switching of the allocation target is suppressed or switched preferentially. Specifically, an allocation target that has less allocation than the desired bandwidth is a switch that suppresses or skips switching to a heavy congestion group with less available bandwidth when the allocation target is switched, or is a lighter with more available bandwidth. Prioritize switching to the congestion group or suppress the switching itself to instruct the instruction unit to reduce the unallocated period. Allocation targets with more allocation than the desired bandwidth give priority to switching to a heavy congestion group with less available bandwidth, or to suppress or skip or switch itself to switching to a light congestion group with more available bandwidth. The instruction unit is instructed to increase the unallocated period accompanying switching.

(Embodiment 2.2)
The implementation unit of the present embodiment switches the allocation target group according to a predetermined order. The instruction unit of the present embodiment detects the allocation or allocation result or allocation history or data continuity history or request or request history associated with the allocation of the implementation unit, and determines the difference between the detection result of a predetermined period and the desired allocation. In response, the execution unit is instructed to change the switching setting. Specifically, the instructing unit sets a setting value that increases the switching frequency to the heavy congestion group, the time belonging to the heavy congestion group, and the number of times of switching itself for an allocation target whose allocation exceeds the desired value. The setting value that increases the frequency of switching to the light congestion group and the time belonging to the light congestion group or decreases the number of times of switching for the insufficient allocation target.

(Embodiment 2.3)
In the implementation unit of the present embodiment, the implementation unit continues the allocation with the allocation instructed by the instruction unit or switches the group according to a predetermined order. The instruction unit of the present embodiment detects the allocation or allocation result or allocation history or data continuity history or request or request history associated with the allocation of the implementation unit, and determines the difference between the detection result of a predetermined period and the desired allocation. In response, the execution unit is instructed to switch the allocation target. Specifically, the instructing unit instructs the executing unit to perform switching that causes at least one of allocation of allocation targets that exceed allocation more than desired, or increase of allocation to insufficient allocation targets. .

(Embodiment 2.4)
In the implementation unit of the present embodiment, the implementation unit continues the allocation with the allocation instructed by the instruction unit or switches the allocation target group according to a predetermined order. The instruction unit according to the present embodiment instructs the switching unit on the switching order according to the difference between the detection result and the desired allocated bandwidth. Specifically, the allocation target having a smaller allocation than the desired bandwidth can be switched from the desired bandwidth to the heavy congestion group after the switching order to the heavy congestion group or the switching to the light congestion group. Allocation targets with a large number of allocations indicate an order in which switching to a heavy congestion group is advanced or switching to a light congestion group is postponed or switching itself is advanced.

(Embodiment 2.5)
The implementation unit of the present embodiment switches the combination of the allocation target groups or the switching setting in any of a predetermined plurality of orders or settings. The instructing unit instructs the execution unit to allocate at least one of the switching targets or the switching setting, at which the allocation becomes smaller for the allocation target exceeding the desired allocation, or the allocation becomes larger for the insufficient allocation target. To do. For example, if ONU 1 to 2 are switched between two wavelengths 1 and 2, the combination of ONU 1 and 2 is wavelength 1 and ONU 3 is wavelength 2 and ONU 1 is wavelength 1 and ONU 2 and 3 are wavelength 2 Thus, the bandwidth allocation of the ONUs 1 and 3 is set to a value corresponding to a predetermined ratio. For example, if switching between 2 wavelengths 1 and 2 and switching settings for ONUs 1 to 3, ONU 1 and 2 are switched to wavelength 1 and ONU 3 is wavelength 2 and ONU 1 is wavelength 1 and ONU 2 and 3 are wavelength 2 Thus, the bandwidth allocation of the ONUs 1 and 3 is set to a value corresponding to a predetermined ratio.

In the following, an example of selection close to a desired allocation is shown.
Reassign ONUs that have a large time product of bandwidth allocation to the lighter congestion group within the allocation target (ONU or ONU queue or ONU class buffer, etc., which is represented by the ONU below) belonging to the more heavy congestion group Determination, or when it is predicted that traffic of a plurality of groups falls below or below a predetermined threshold, the ONUs belonging to the group are regrouped or suspended by another group in order to stop communication of at least some of those groups The determination of suspending a group to which an active ONU does not belong, or when it is predicted that traffic of one or a plurality of groups exceeds or exceeds a predetermined threshold, communication of at least some groups is started and ONUs belonging to the group are selected. Activate the ONU that was regrouped or paused to the group that started The determination of the equal, performed by the instruction unit, executing unit performs regroup following the instructions based on the determination. Alternatively, the implementation unit regroups according to a predetermined cycle or opportunity, and the implementation unit is regrouped so that a desired allocation is made based on a standard such as fairness.

  Here, heavy congestion means that the available bandwidth is small for the allocation target, such as a wavelength that accommodates a large number of requested allocation targets, a wavelength that can originally be transmitted compared to other wavelengths, and the like.

[1] First Operation In the first operation, among ONUs belonging to a more heavily congested group, ONUs having a larger allocation time product are regrouped into lightly congested groups. An ONU having a large allocation time product among ONUs belonging to a heavy congestion group is, for example, an ONU having a large allocation time product compared to other ONUs belonging to the same group. An ONU having a larger allocation time product than other ONUs is, for example, an ONU having the largest allocation time product in a group, or a predetermined number of ONUs in a group in the descending order of allocation time product, or in a group. It is an ONU having an allocation time product that is greater than a predetermined value or an average value of allocation time products for all the ONUs to which it belongs. The predetermined value is, for example, a value obtained by dividing the sum of the time products of the bands of all the groups at a predetermined time, for example, the observation time, by the total number of ONUs in all the groups, the number of active ONUs, or the number of ONUs whose requirements are not satisfied. Of the ONUs belonging to the heavy congestion group, the transmitter / receiver having a larger time product belonging to the heavy congestion group than the other ONUs belonging to the group, among the ONUs belonging to the heavy congestion group. Number of communication interruptions due to a group change compared to other ONUs belonging to the group among ONUs belonging to the light congestion group and ONUs belonging to the heavy congestion group having a smaller time product belonging to the light congestion group than other ONUs belonging to the group The same applies to an ONU having a small communication interruption time product due to a group change. Here, the congestion of the group is any of the following or any combination thereof.

(1) The number of accommodated ONUs per group: the greater the number of accommodated ONUs, the more congestion (2) The number of ONUs active (transmitting) in the accommodated ONUs per group: the greater the number of ONUs active in the accommodated ONUs, the greater Congestion (3) Number of ONUs whose allocation is less than the request in the accommodated ONUs for each group: The greater the number of ONUs whose allocation is less than the requirement in the accommodated ONUs, the more congestion (4) The sum of the requests of all ONUs accommodated for each group Average value: The total sum of requests of all ONUs accommodated or the larger the average value, the greater the congestion. (5) Total sum or average value of all ONUs accommodated for each group: Total or average of all ONUs accommodated When the value is smaller, the congestion is higher, and when the value is larger, the reciprocal number is used. (6) The total sum or average of the allocation of ONUs whose allocation does not satisfy the requirement among all ONUs accommodated in each group. Value: When the total or average value of ONU allocations that do not satisfy the requirements of all ONUs to be accommodated is smaller, the congestion is higher, and the larger values are the heavy congestion, the reciprocal number is used. (7) Accommodating each group ONU allocation value with maximum allocation among ONUs to be used: When the allocation value of ONUs with the maximum allocation among ONUs to be stored is smaller, the congestion is larger, and when the larger value is treated as heavy congestion, the reciprocal number thereof is used (8) group The value of the ONU whose allocation is the maximum for the ONU that does not wait for the request in the ONU to be accommodated for each of the ONUs: the congestion value is smaller as the allocation value of the ONU whose allocation is the maximum for the ONU that does not wait for the request in the accommodated ONU is smaller When the larger value is treated as heavy congestion, the reciprocal of those is used. (9) The allocation value of the ONU with the smallest allocation in the ONU accommodated for each group: the allocation of the ONU with the smallest allocation in the accommodated ONU When the value is smaller, the congestion is greater, and when the value is greater, the reciprocal is used. (10) The ONU allocation value of the ONU whose allocation is not waited for the request in the ONU accommodated for each group: When the allocation value of an ONU whose allocation is an ONU that does not wait for a request and the allocation of the ONU with the smallest allocation is smaller, the congestion is larger, and when the larger value is treated as heavy congestion, the reciprocal of those is used. (11) The ONUs that are accommodated for each group Compared to other ONUs, there are more time products belonging to heavy congestion groups, less time products belonging to light congestion groups, fewer assignments, and time products of communication interruption due to group switching. The greater the number of ONUs that have a large number of communication interruptions due to group changes or the greater the number of ONUs, the more congestion

  It should be noted that a predetermined value or more may be heavy congestion, and a value less than the predetermined value may be light congestion. The predetermined value is, for example, the value obtained by dividing the number of accommodated ONUs of all groups by the number of groups in (1), or the value obtained by rounding up or down the value, and the number of active ONUs of all groups by the number of groups in (2). Value, or a value obtained by rounding up or down the value, a value obtained by dividing the number of ONUs for which all group assignments do not meet the requirements in (3) by the number of groups, or a value obtained by rounding up or down the value, or all values in (4) A value obtained by dividing the sum or average value of the ONU requests of the group by the number of groups, or a value obtained by rounding up or down the value. In (5), the sum or average value of all group ONU allocations is divided by the number of groups. Or the value obtained by rounding up or down the value, or the value obtained by dividing the total or average value of ONU allocations that do not meet the requirements of all groups in (6) by the number of groups. Alternatively, a value obtained by rounding up or down the value, (7), a value obtained by dividing the sum of the allocation values of the ONUs having the largest allocation in the ONUs of each group by the number of groups, or a value obtained by rounding up or down the value ( 8) The value obtained by dividing the sum of the allocation values of the ONUs whose allocation is the maximum by the ONUs whose allocation is not waiting for the request by the ONUs of each group, or a value obtained by rounding up or down the value, (9) A value obtained by dividing the sum of the allocation values of the ONUs with the smallest allocation among the ONUs of the group by the number of groups, or a value obtained by rounding up or down the value. In (10), an ONU whose allocation does not wait for a request in each group ONU. A value obtained by dividing the sum of the allocation values of the ONU with the smallest allocation by the number of groups, or a value obtained by rounding up or down the value. In (11), the number of ONUs of 1 or all groups is the number of groups. Half of a value obtained by dividing, or half of the up or down to a value that value, and the like. Further, when the groups are arranged in the order of congestion, the group on the congestion side from half may be heavy congestion, and the other groups may be light congestion.

  The above (1) is the simplest and is suitable when all ONUs are always active. When there is an inactive ONU, it is difficult to determine congestion with the setting (1). The above (2) is suitable when all active ONUs are Greedy transmitters. Here, a Greedy transmitter means a bandwidth that is requested according to an available bandwidth, such as TCP / IP, more than the bandwidth allocated at that time without controlling the bandwidth to be less than or equal to the usable bandwidth. This means a transmitter that requires a certain bandwidth. In the case of Grayy, congestion can be determined with a simple setting as in (2) above.

  On the other hand, when at least some of the ONUs are not Grayy, the request is different for each ONU, so it is difficult to clearly determine the congestion with the setting (2). In consideration of this case, (3) to (11) above.

  The above (3) is a method for determining congestion using the number of ONUs, and the above (4) to (10) are methods for determining congestion using the total number / average / maximum value / minimum value of requests or allocations of accommodated ONUs. Among these, the above (3), (6), (8), and (10) are more precise congestion determination methods focusing on the request itself or the ONU in which the request is not satisfied. The above (11) is a congestion determination method using the number of ONUs that are in an unfair state due to more communication interruptions and fewer assignments than other ONUs.

  Moreover, it is desirable that the allocation used in the above (5) to (10) is a band permitted to be transmitted from the OLT, a band actually used, or a band permitted to be transmitted with the support of the request. Bandwidth allocation without request support (unnecessary allocation) is, for example, “Bandwidth distribution method realizing low delay in B-PON DBA”, Manabu Yoshino, Shinichi Yoshihara, Hiromi Ueda, 2002 IEICE Communication Society. There are events as shown in B-8-8. There is also an unused band that has been requested but is not used to suppress fragmentation of transmission information. For example, it is a fractional band less than one packet. For this reason, the assignments (5) to (10) are permitted for transmission with the support of the actually used band or request that does not include the above-mentioned unnecessary assignment or unused band assignment from the viewpoint of fairness. It is desirable to use the same band.

  The ONUs whose allocation increases due to the group change are the ONUs that remain in the group from which the ONU is lost due to the group change, and the ONUs that are added to the light congestion group depending on the case. If the allocation of ONUs to be regrouped by light congestion increases from the heavy congestion group, it is added in the light congestion group rather than the allocation in the previous heavy congestion group if the communication interruption time due to group change is not considered. After that, the allocation in the group is large. For example, when 3ONUs are distributed between two groups with the same bandwidth used in the description of the conventional example, the added ONUs always share the bandwidth with the 2ONUs before and after the group change, so they always belong to the heavy congestion group. The allocation of the ONU is not increased by changing the group. Furthermore, when communication interruption time due to group change is taken into consideration, the allocation is further reduced due to group change. Note that the allocation of ONUs that previously belonged to the group to which the new ONU was added decreases.

  Regarding the ONU, the communication state to be observed varies depending on the fairness to be realized. For example, if it is fair that the allocation is equal or close to a predetermined ratio corresponding to the weight of each ONU, the allocation is observed. The first operation is an operation suitable for this fairness.

  In order to make the allocation ratio, which is the ratio of the allocation to the guaranteed band, which is the band that must be guaranteed, or the allocation ratio to the request for requesting transmission permission from the transmitter, the allocation ratio is observed as the communication state. Here, the request may be determined according to the past communication history as well as the declared value of the request from the ONU or the value calculated by smoothing or the like. The communication history may be a history of a window at a fixed time interval in the past, a history of a sliding window for a fixed time, or a history based on a weighted average or an exponential average.

  When allocating a bandwidth that can be shared between transmitters at a predetermined ratio (for example, 1: 1: 1), the total of the ratio of the bandwidth that can be shared × the ratio of the corresponding transmitter ÷ the ratio of all transmitters is effectively calculated. As a guaranteed band, the allocation ratio thereto may be observed as a communication state.

  Further, the comparison of the allocation ratios described above may be limited to only transmitters that have a higher demand than allocation. Further, the comparison may be performed with respect to a band that is fixedly assigned regardless of a request, a band obtained by reducing the allocation for the priority class, a group other than the group that is fixedly allocated or the group for the priority class.

  In the first operation, ONUs having a large allocation time product are switched among ONUs belonging to the heavily congested group, so that group switching is continued only for the same ONU, and the allocation does not decrease. , Bandwidth can be allocated so as to be fair among the ONUs. For example, in the case of 2 groups 3 ONUs, when all ONUs always request more than the allocation, the ONUs to be switched are sequentially switched as ONU1-> ONU2-> ONU3.

  For this reason, the communication interruption time associated with the group change and the time product belonging to the heavy congestion group and the time product belonging to the light congestion group are equal on average, and the bandwidth allocation within the group is determined based on the past ONU. If the allocation is performed according to the weighting at any time without considering the allocation history, fair bandwidth allocation among the ONUs across the groups becomes possible.

  In the first operation and the second and third operations described later, when the difference in congestion between the groups is within a certain range, the group change may not be performed. Here, the difference in congestion between groups is within a certain range, for example, when the value is equal to or less than the value corresponding to the communication interruption time due to group change, or the degree of congestion that is improved when group change is executed. This is the case when the value is less than or equal to. In such a case, it is desirable to execute the first operation and the second and third operations described later until the allocation between individual ONUs falls within a certain range from the fair allocation.

  Here, “within a certain range from fair allocation” is, for example, not more than a value corresponding to the communication interruption time associated with the group change, or not more than a value equivalent to the degree of fairness improved when the group change is executed.

  This is because the difference in congestion between groups may fall within a certain range before fairness between the ONUs is realized due to changes in requests of individual ONUs. Under this latter condition, the heavy congestion group is a group to which ONUs with less allocation than fair allocation belong. That is, the determination in (11) above is made. Here, until the difference in congestion between the groups is within a certain range, the congestion of the group is determined other than the above (11), and the congestion difference between the groups is within a certain range by the method used for the determination. When it becomes, it is good also as switching to the determination by the method of said (11).

  The observation time may be observed with a fixed-period observation window, or may be observed with a sliding window in which the observation time is a moving average over a predetermined period in the past, or the past history is exponential. It may be an observation that is forgotten and is exponentially averaged with emphasis on recent observations.

  In addition, as a method of observing the bandwidth for each ONU, there are a method of observing the communication interruption time associated with the group change as a time of zero allocation, and an observation method ignoring the communication interruption time associated with the group change. As an operation, it is desirable to observe the communication interruption time associated with the group change as a time of zero allocation.

For example, suppose that the controller observes assignments periodically. Furthermore, the controller forgets the observed bandwidth exponentially, and effectively observes the recent observation, taking into account the communication interruption time associated with group switching, with an observation time averaged exponentially. . Further, it is assumed that the request of each ONU is larger than the allocated bandwidth. Assume that the band of the j-th group is Gj, the number of accommodated ONUs at time T is Nj (t), the coefficient for observation forgetting is (1-k), and the allocation of the i-th ONU is Bi (t). In this case, the allocation history in the observation time is RBi (t)
RBi (t) = kBi (t) + (1-k) RBi (t)
It is. Here, the allocation Bi (t) of the i-th ONU is Gi / Nj (t) when belonging to the j-th group, and the interruption time associated with the group change is zero. The forgetting coefficient is a value that sufficiently increases the time until forgetting compared to the switching cycle.

[2] Second operation In the second operation, among the ONUs belonging to a group with more congestion, the ONU or group congestion with a larger time product belonging to the more congestion group is more severe. Of the ONUs belonging to the congestion group, the ONUs having a smaller time product belonging to the lighter congestion group are regrouped. The time product is, for example, the value illustrated in the first operation of congestion for each group, and may be the time product, or the congestion is divided into a plurality of stages and assigned a predetermined value, for example, light congestion is set to 0. The heavy congestion may be assigned as 1 and the time product of the value may be used.

  Compared with the first operation, this operation may be performed by observing at least only the stay time in the light congestion group and the heavy congestion group without observing the band of the individual ONU itself. This makes it easy to observe. Furthermore, since the actual bandwidth allocation value for each ONU within the group is not used for group change, it is easy to control the bandwidth allocation within the group separately from the allocation of ONUs between groups. The fair allocation can be realized if the bandwidth allocation within the group is fair, the change in the distribution status of ONU requests before and after switching can be ignored, and the congestion status between groups due to group switching is leveled.

  When the execution unit changes the group according to a predetermined cycle or opportunity, it is single or so that the difference is resolved from the allocation with a low or high allocation history for a predetermined period from the predicted allocation with a request or a request allocation. An instruction is given to preferentially or prevent group change for a plurality of predetermined periods.

[3] Third Operation The third operation regroups ONUs having a small communication interruption time product due to regrouping among ONUs belonging to a group with more congestion of the group. In the same example as the first operation, the time product RTi (t) of the communication interruption time Ti (t) is
RTi (t) = kTi (t) + (1-k) RTi (t)
It is.

  Note that the communication interruption time product associated with the group change may be replaced with the number of times of switching when the communication interruption time can be regarded as different for each ONU.

  The time product of communication interruption is effectively limited due to reasons such as insufficient update of the request history compared to the case where the allocation amount is effectively changed by the allocation algorithm etc. Time may be included, and the limited time may be included as a time obtained by multiplying the limited amount as a coefficient.

  Therefore, in this operation, the communication interruption time associated with the group change and the time product belonging to the heavy congestion group and the time product belonging to the light congestion group are equalized, and the bandwidth allocation in the group is the same as that of the past ONU. If the allocation is performed according to the weighting at any time without considering the allocation history, the fair bandwidth allocation between the ONUs across the groups becomes possible as in the first operation.

  Furthermore, since the controller does not maintain the allocation for each group but only the time product of communication interruption, this operation is easier to maintain and process the history than the first operation, as in the second operation. It is.

[4-1] Fourth operation (part 1)
The fourth operation (part 1) suppresses the variation in the communication interruption time product accompanying the group change for each ONU within a certain range between the ONUs. Within a certain range is, for example, less than the communication interruption time associated with one group change. At the time of switching, the group may be switched from the heavy congestion group to the light congestion group based on the congestion of the group as in the first to third operations, or an example of a fourth operation (part 3) described later. The group may be changed cyclically as indicated by.

  When the group is changed cyclically, it is desirable that congestion such as the number of active ONUs or requests of each group is leveled. Here, the situation in which congestion such as the number of active ONUs or requests is leveled is, for example, the sum of the allocation of ONUs in which the difference in the number of active ONUs is 1 or less between groups or the allocation does not exceed the request The difference between the groups is the following situation of ONU allocation in which allocation does not exceed the request between groups.

  In such a situation and when the group is changed cyclically during the time when the request situation can be regarded as being almost constant, at most all the ONUs may change the group to all the groups. When the number of similar congestion groups and the number of ONUs whose active or allocation does not exceed the request are plural, the group may be changed to a group that is half the number of groups. In any case, in the long term, the communication interruption time associated with the group change and the time product belonging to the heavy congestion group and the time product belonging to the light congestion group approach each evenly, and the bandwidth allocation within the group is If allocation is performed according to the weighting of each time without considering the past ONU allocation history, fair bandwidth allocation among ONUs across groups can be easily performed.

[4-2] Fourth operation (part 2)
The fourth operation (part 2) suppresses variations in the period during which the ONU is accommodated in the heavy congestion group and the light congestion group within a certain range between the ONUs. Within a certain range is, for example, the maximum bandwidth that can be allocated to a time corresponding to the communication interruption time associated with switching. At the time of switching, the group may be changed from the heavy congestion group to the light congestion group as in the first to third operations, or cyclically as shown in the fourth operation (part 3) described later. You may change the group. In any case, in the long term, the communication interruption time associated with the group change and the time product belonging to the heavy congestion group and the time product belonging to the light congestion group are equally close, and the bandwidth allocation within the group If the allocation is performed according to the occasional weighting without considering the ONU allocation history, fair bandwidth allocation among the ONUs across the groups can be easily performed.

[4-3] Fourth operation (part 3)
The fourth operation (part 3) is a combination of the fourth operation (part 1) and the fourth operation (part 2). That is, in the observation period for observing the communication state for each group, the period in which each first transmitter / receiver (16, 17) stays in which period, the communication interruption time associated with the group change, and the fairness A group designation instruction is issued so that the communication interruption time associated with switching of all the first transceivers (16, 17) and the time product of the congestion of the group to which the group belongs belong to each other.

  This operation is the fourth operation (part 1), in which congestion leveling cannot be performed between groups, and the ONU belonging to the heavy congestion group and the light congestion group always belong to each group change cycle. When a situation that is classified as ONU occurs, the unfairness can be corrected. In addition, this operation corrects the unfairness even when the communication interruption time associated with the group change is extremely large and the fourth operation (part 2) causes a large allocation difference due to the large number of switching times. can do. This is because this operation can equalize the communication interruption time associated with the switching, and the times belonging to the groups of light congestion and heavy congestion, respectively.

  The product of the times that belonged to the light congestion and heavy congestion groups is simply calculated if the congestion levels between the light congestion groups and the congestion levels between the heavy congestion groups are the same throughout the observation time. What is necessary is just to take the product of the time which belonged to the group of light congestion and heavy congestion, respectively. If the degree of congestion differs from time to time for each group, the product of the times to which they belonged may be obtained by accumulating a value obtained by multiplying the belonging time by the degree of congestion. When accumulating a value obtained by multiplying the affiliation time by the degree of congestion, one time accumulation is performed without individually integrating the time product belonging to the light congestion group and the time product belonging to the heavy congestion group. It may be held as a value. Communication interruption time due to group change may be accumulated individually, but it was considered as a situation where communication was not possible at all due to heavy congestion and belonged to the time product and heavy congestion group that belonged to the light congestion group You may accumulate together with time product. When integrating together, there is an effect of reducing the value to be held.

  The following explanation is given using an example in which the allocation is fair. For example, if the wavelength is 2 wavelengths, the weights and switching times for bandwidth allocation of all transmitters are the same, and one is light congestion and the other is heavy congestion, light congestion and heavy congestion will be approximately equal to all transmitters. It belongs to the group identified by each wavelength.

  If the switching time is the same, the number of ONUs of the group identified by the belonging wavelength, the sum of requests for the guaranteed bandwidth, and the time product of the sum of the requests for the bandwidth obtained by subtracting the fixed bandwidth from the guaranteed bandwidth minus the fixed bandwidth. What is necessary is just to be equal.

For example, the allocated band and its time at the light congestion wavelength for the transmitter i, the allocated band and the time at the heavy congestion wavelength, and the allocated band and the time at the communication interruption time associated with the group change are respectively Bli, Tli, Bsi, and Tsi. , Bhi, and Thi, control is performed so that Bhi · Thi + Bsi · Tsi + Bli · Tli is constant for all transmitters i as shown in Equation 1.
(Formula 1) ∀i, Bhi · Thi + Bsi · Tsi + Bli · Tli = const
Hereinafter, (Formula 1) is effectively satisfied by cyclically assigning. Here, for the sake of simplicity, the communication state of the ONUs constituting the group is shown as an example in which the group change is completed (all are Gray). However, even if it fluctuates during one round, it can be regarded as the same in terms of statistics and long-term, and therefore, the same effect as this example can be obtained. In this case, each value of Formula 1 is (Formula 2) Thi + Tli = Const,
Bhi = BW / ([N / L]),
Bsi = BW / ([N / L] +1)
It can be expressed by the relationship. Here, BW is a band for each wavelength, N is the number of transmitters, L is the number of wavelengths, and [] is rounded down.

(Embodiment 3)
FIG. 3 shows a first function deployment example, and FIG. 4 shows a second function deployment example. In the first function deployment example, the CPU version 25 of the network device includes an instruction unit that is a function. The instruction unit is not limited to the independent CPU version 25 as shown in the figure, and at least one of the OLT outside, the OLT inside, the OLT SW 22, the OSU 21, and λCard (light transmission or reception of one or more wavelengths) On the line card to be performed), and can be an arbitrary arithmetic processing location connected to an implementation unit such as PON MAC, λTRx (one or more optical transceivers). In the second example of function deployment, an instruction unit, which is a softwareized function, exchanges instruction information with the server 26 in an arbitrary device connected to the network device via the network, for example, an external server 26. Are provided with a conversion unit 27. For example, an instruction unit obtained by converting a part of the DBA function into software is provided in the CPU version 25 or the server 26. An implementation unit that is another part of the DBA function is provided in the OSU 21. However, the implementation unit is not limited to the MAC chip on the OSU 21, and may be configured to be connected to an instruction unit such as the OLT outside, the OLT inside, the OLT SW 22, the OSU 21, the λCard, and the λTRx. In addition, although some software functions are shown in the figure, other software functions may be provided, or software functions related to the functions provided in the main eight functions may not be provided. Also good.

  3 and 4, as hardware of the network device, λcard (TRx11 shown in FIG. 6 of the configuration example described later, PON MAC in FIG. 6 is illustrated on λCard, but is not necessarily deployed on λCard, Also, the OSU 21, SW22 (SW12 or SW13 shown in FIG. 6), the control unit 24 (control unit 14 shown in FIG. 6), the CPU version 25, and the instruction information are in accordance with the communication protocol. Although the conversion unit 27 having a format such as an Ethernet (registered trademark) frame has been described, the present embodiment is not limited to this. For example, the CPU version 25 may be included in λcard, OSU 21, SW 22, control unit 24, or the like as they are or distributed. In addition, although the processing is illustrated as being performed by the CPU, a part or all of the processing may be performed on an alternative having a processing function, for example, a processor such as a GPU, NPU, or DSP other than the CPU, or an FPGA. Further, a converter for converting input / output such as an instruction with the server 26 or the like into a format that can be transmitted through a transmission path such as an Ethernet frame is not an Ethernet frame if the input / output such as the instruction with the server 26 is possible. The frame may be converted to a frame, TDM, or the like. The conversion unit 27 is not necessary if an instruction or the like can be transmitted to and received from the server 26 without using the conversion unit 27. Further, as shown in FIG. 6 of the configuration example described later, the NNI side of the SW 22 includes a proxy unit 15 that processes a signal input / output to / from the SW or a Cloud that is a processing device such as an external server 16 or a plurality thereof. It may be. Each function may be appropriately arranged according to a request for processing capacity or processing delay. Further, the OSU 21 may be provided with SW22 of this figure (SW12 or SW13 in the figure of the configuration example described later), or may be provided separately from SW22 of this figure (SW12 when SW13 is provided with the example of configuration described later). May be provided. It is desirable that the functions of the SW22 are appropriately shared according to the processing capability of the SW22 without overlapping between the SW12 and the SW13, but may be overlapped.

(Embodiment 4)
Although the TWDM-PON is illustrated in the first embodiment shown in FIG. 1, it may be applied to the TDM-PON. In the TDM-PON, the first embodiment is provided except that the function required for wavelength division multiplexing of the wavelength resource in the PON section of the ONU-OLT during the ONU, such as λ setting switching (DWA), is not necessary. It is the same.

  In the first embodiment, TWDM-PON is exemplified. However, PON sharing resources other than wavelength and time, for example, OFDM (Orthogonal Frequency-Division Multiplexing) -PON that divides and multiplexes one or more wavelengths of electrical frequency resources. SCM-PON that divides and multiplexes the frequency resources of one or a wavelength, may be divided and multiplexed by OFDM in the optical domain, may be used in combination with core division multiplexing, or core division multiplexing (spatial division multiplexing) It may be used in combination, mode division multiplexing may be used together, CDM-PON that performs division multiplexing with codes of electrical or optical or core wire or core or mode or (orthogonal) frequency or any combination thereof. It may be applied, or only division multiplexing other than time division multiplexing and wavelength division multiplexing may be performed. The same applies if the function corresponding to the function required for wavelength division multiplexing of the wavelength resource of the TWDM-PON is replaced with the function corresponding to the function required for division multiplexing to each resource to be multiplexed.

  Although the TWDM-PON is taken as an example in the first embodiment, the same effect can be obtained with other PONs by similarly handling a frame for identification in the PON section. For example, in the case of IEEE standard GE-PON, 10GE-PON, etc., instead of a GEM frame, an LLID is assigned so that the LLID-added frame is connected between the SW and the other parts. Good.

Hereinafter, a configuration example of the communication system will be described with reference to FIG.
First communication system configuration example The first communication system configuration example includes a transmission / reception unit (TRx) 11, a switch unit (SW) 12, a switch unit (SW) 13, a control unit 14, a proxy unit 15, And a server 16.

  The OLT may be composed of TRx11, SW12, SW13, and control unit 14, or may be composed of TRx11, SW12, SW13, control unit 14, and server 16. The OSU may be configured from TRx11, may be configured from TRx11 and SW12, or may be configured from TRx11 and SW13.

  TRx11 having different wavelengths (λA to λN) is connected to SW12. TRx11 is autonomous, or controlled from other components such as SW12, SW13, control unit 14, proxy unit 15 and server 16, or other components such as SW12, SW13, control unit 14, proxy unit 15 and server 16 Or a part or all of the traffic of the ODN or SW 12 is added according to a predetermined procedure, or at least a part of a tag of VLAN, priority, discard priority, destination, etc. or a combination thereof is added or controlled. Process with at least one of aggregating or distributing or allocating or replicating or folding or transparent or a combination thereof without deletion or reassignment or modification.

  SW12 is connected to SW3.

However, the uplink is not necessarily aggregated. For example, in a communication system configuration in which TRx11 of different wavelengths is connected to a device at the latter stage when viewed from the ONU side (in this communication system configuration example, it is exemplified by SW12, but may be SW13, proxy unit 15 or the like), distribution to each wavelength is possible. Mainly, tags such as tags representing distribution, aggregation, transmission as it is, VID and priority discard may be added or replaced. Furthermore, in a communication system configuration in which TRx 11 of the same wavelength is connected to a device at the subsequent stage when viewed from the ONU side (in this communication system configuration example, it is exemplified by SW 12, but may be SW 13, proxy unit 15, etc.), upstream traffic is aggregated. Mainly, distribution, distribution, transmission as it is, tag addition or replacement may be performed, and downlink traffic may be distribution, aggregation, distribution, transmission, tag addition or replacement. Further, in the device at the rear stage when TRx11 of at least some wavelengths and TRx11 of other wavelengths are viewed from the ONU side (in this communication system configuration example, illustrated as SW12, SW13, proxy unit 15 or the like may be used) Any of distribution, aggregation, distribution, transmission, tag addition, or replacement may be used, or at least some combination may be used. Which of these will depend on the service policy.

For example, the control unit 14 included in the communication system configuration controls the case of controlling at least one of 11 to 15 (TRx11, SW12, SW13, proxy unit 15 in this communication system configuration example), and prepares the communication system configuration without control. Control information may be transferred to at least one of 11 to 15 (TRx11, SW12, SW13, proxy unit 15 in this communication system configuration example).
