Description

Bandwidth scheduling method, ONU register method, device and OLT

Technical field

The present invention relates to the communications field, in particular to a kind of bandwidth scheduling method, ONU register method, device and OLT。

Background technique

With the fast development of broadband services, user docks the demand into network bandwidth and increases substantially, passive optical network (Passive Optical Network, referred to as PON) is a kind of important technical of current user's access.PON system is logical Often by optical line terminal (Optical Line Terminal, referred to as OLT), optical network unit (Optical Network Unit, referred to as ONU or ONT Optical Network Terminal ONT) constitute Optical Distribution Network (Optical Distribution Network, referred to as ODN) composition.ODN is usually point-to-multipoint structure, i.e. the multiple ONU of OLT connection.Usual OLT to ONU is down direction, ONU to OLT be up direction.

By a wavelength to communicating, OLT opens peace and quiet window in downstream wavelength and requests ONU's OLT and ONU Identity information, after ONU reports that identity information, OLT obtain the identity information of ONU in upstream wavelength, again in downstream wavelength Open peace and quiet window simultaneously sends distance measurement request, and ONU replies ranging response in upstream wavelength, and OLT completes ranging, and OLT is under Row service conditions sends data to ONU, and is that ONU distributes band according to the uplink service situation of ONU or the bandwidth request of ONU Width, ONU send upstream data in the bandwidth for distributing to oneself.

It is passive that global operator has deployed gigabit passive optical network (Gigabit PON, referred to as GPON), ether Optical-fiber network (Ethernet PON, referred to as EPON).In order to promote user's access bandwidth, operator needs to dispose bandwidth higher Ten gigabit passive optical networks (10Gigabit PON, referred to as XG-PON1), ten gigabit ethernet passive optical networks (10Gigabit EPON, referred to as 10GEPON) etc..In these technologies, it is remote that GPON, XG-PON1 belong to International Telecommunication Union Journey communication standardization tissue (ITU-T) standards system, EPON, 10GEPON belong to Institute of Electrical and Electric Engineers (IEEE) Standards system, the PON technology with standards system have fully considered the demand of upgrading evolution during standard formulation, or Person's physical layer, protocol layer compatibility be stronger or the tailor scheme of upgrading evolution, therefore with the PON skill of standards system Art upgrading evolution is easier to, and is upgraded and accomplished to influence minimum as far as possible on the ONU of normal work in evolution process.For example, ITU-T GPON and XG-PON1 under standards system use entirely different uplink and downlink wavelength, and a GPON ONU is substituted for XG- After PON1ONU, because uplink and downlink wavelength is changed, it is naturally linked into XG-PON1OLT, it will not be to GPON OLT Under other ONU have an impact.

But when deployment scenario changes, for example, from fiber to the home (Fiber To The Home, referred to as FTTH) It, may when being changed into fiber to the floor (Fiber To The Building, referred to as FTTB), or being changed into FTTH from FTTB It is related to the upgrading of different standard, for example, upgrading to 10GEPON from GPON, or upgrades to XGPON1 from EPON.Different standard upgrading is deposited It is since system is different, relevant upgrading evolution needs summation process undefined in larger difficulty；Further, since different standard it Between the uplink and downlink wavelength that uses may be overlapped, when causing to upgrade some ONU, other ONU will receive influence；Therefore, in different standard When upgrading, need all ONU are offline, then carry out by the gross ONU upgrading, therefore, it is impossible to accomplish smooth evolution upgrade, user can be given Access service bring bigger influence.

Specific embodiment

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and in combination with Examples.It should be noted that not conflicting In the case of, the features in the embodiments and the embodiments of the present application can be combined with each other.

It should be noted that description and claims of this specification and term " first " in above-mentioned attached drawing, " Two " etc. be to be used to distinguish similar objects, without being used to describe a particular order or precedence order.

A kind of bandwidth scheduling method is provided in the present embodiment, and Fig. 1 is bandwidth scheduling side according to an embodiment of the present invention The flow chart of method, as shown in Figure 1, the process includes the following steps:

Step S102, OLT are according to the quantity of the ONU under every kind of PON standard in a variety of PON standards and/or the upstream of ONU Amount, determines the standard upstream bandwidth of every kind of PON standard；

Standard upstream bandwidth is scheduled to corresponding PON standard by step S104, OLT, wherein standard upstream bandwidth is used for OLT is communicated with the ONU under corresponding PON standard.

It through the above steps, is every kind of PON system by OLT under the scene that a variety of PON standards coexist or need to coexist Formula determines standard upstream bandwidth, and determining upstream bandwidth is scheduled to these PON standards respectively.Due to each PON standard quilt It scheduled respective upstream bandwidth, therefore the bandwidth allocation function of each PON standard can be according to the scheduled standard uplink arrived Bandwidth further distributes upstream bandwidth for the ONU under the standard, to realize coexisting for the ONU of a variety of PON standards.Using Above-mentioned steps provided in an embodiment of the present invention realize the adaptive scheduling to the upstream bandwidth in ODN network with PON standard, It solves the problems, such as the different standard smooth upgrade that cannot achieve ONU, realizes the different standard smooth upgrade of ONU, improve ONU liter The efficiency of grade.

It should be noted that in the case where wavelength-division multiplex, signified standard upstream bandwidth, uplink in the embodiment of the present invention Bandwidth is upstream wavelength；In the case of time division multiplexing, standard upstream bandwidth signified in the embodiment of the present invention, upstream bandwidth are Use the duration of upstream wavelength.

Above-mentioned standard upstream bandwidth refers to the resource for being exclusively used in receiving the ONU registration and uplink traffic of a kind of PON standard, In the resource, the ONU of one or more this kind of PON standard can be registered and be transmitted uplink by time division multiplexing mode Flow.

After the standard upstream bandwidth distribution for realizing different PON standards through the above steps, the bandwidth of each PON standard Distribution function then can distribute upstream bandwidth for respective ONU.By taking the first PON standard as an example, in OLT by multiple standard uplink bands Width is scheduled to respectively after corresponding PON standard, and the first standard upstream bandwidth that OLT dispatches the first PON standard distributes To the ONU of the first PON standard.

Distribution to the upstream bandwidth of ONU, since the registration of ONU.Optionally, by taking the first PON standard as an example, OLT root It is the open quiet window of the ONU of the first PON standard in the first standard upstream bandwidth according to preset configuration or user instruction；OLT The uplink registration information of the ONU of the first PON standard is detected in quiet window；In the uplink for the ONU for detecting the first PON standard In the case where registration information, OLT completes the registration of the ONU of the first PON standard；OLT is first in the first standard upstream bandwidth The ONU of PON standard distributes upstream bandwidth.By this way, the registration of ONU is realized, and after ONU is registered on OLT, is The ONU is assigned with upstream bandwidth.Wherein, in open quiet window, preset configuration can be set as timing and open quiet window； The user instruction of open quiet window can also be sent when needing to register new ONU to OLT, carry quiet window in user instruction The information of mouth, such as: open duration, wavelength etc..

Above-mentioned preset configuration refers to: the configuration information that user is written according to demand, these configuration informations are used to indicate OLT According to belonging in a kind of standard upstream bandwidth of PON standard for bandwidth scheduling center distribution, in the suitable time or with predetermined Frequency open scheduled duration time window, to receive the registration of the ONU of this kind of PON standard, and further work normally hair The data sent.

Optionally, after thering is new ONU to be registered on OLT, then correspond to the ONU's being registered on OLT under PON standard Quantity will change.At this point, under some strategies, the standard upstream bandwidth of corresponding PON standard redefine and Scheduling.Such as: OLT updates the quantity of the ONU in a variety of PON standards under every kind of PON standard and/or the uplink traffic of ONU；OLT According to the quantity of updated ONU under every kind of PON standard and/or the uplink traffic of updated ONU, every kind of PON standard is determined Updated standard upstream bandwidth；Updated standard upstream bandwidth is scheduled to corresponding PON standard by OLT.Pass through above-mentioned side The registration scenarios of ONU may be implemented in formula, increase standard upstream bandwidth one by one for the PON standard where each ONU, realize ONU's The adaptive scheduling of registration and upstream bandwidth one by one.

In embodiments of the present invention, updated ONU under the quantity or every kind of PON standard of the ONU under every kind of PON standard Quantity include but is not limited at least one of: it is to be registered under the ONU that works under every kind of PON standard, every kind of PON standard Registered ONU under ONU, every kind of PON standard.By this way, various fields can be adapted to the strategy of flexible setting bandwidth scheduling Scape demand.

Optionally, the ONU and/or ONU to be registered that work under a kind of PON standard and/or registered ONU and/or The uplink traffic of ONU is bigger, then the standard upstream bandwidth that this PON standard is scheduled for will be bigger.

Optionally, upstream bandwidth can be disposably assigned, and can also be dynamically distributed according to some cycles.Due to uplink Total bandwidth may be fixed；Carry out upstream bandwidth adaptive scheduling when, can reserve a part of upstream bandwidth for from Each PON standard is distributed in adaptation.

For example, there are in the ODN of two kinds of PON standards, the first PON standard is assigned with standard upstream bandwidth A1, second PON standard is assigned with standard upstream bandwidth A2, reserves upstream bandwidth B；At a time, there is ONU note under the first PON standard It sells, there is new ONU registration under second of PON standard；At this point it is possible to reduce or remain unchanged standard upstream bandwidth A1, increase Add formula upstream bandwidth A2；The increased part standard upstream bandwidth A2 is a part of reserved upstream bandwidth B, is also possible to standard A part of upstream bandwidth A1 reduction.Using this kind of mode, the standard upstream bandwidth phase distributed between each standard can be made It is mutually independently increased or reduces, reduce the computation complexity of upstream bandwidth scheduling.Disadvantage is that in reserved a part Row bandwidth.It may result in the idle waste of part upstream bandwidth.

When carrying out the adaptive scheduling of upstream bandwidth, upstream bandwidth can not also be reserved.

For example, OLT determines the second system of the 2nd PON standard for being not yet dispatched to standard upstream bandwidth in a variety of PON standards Formula upstream bandwidth；OLT adjusts the third standard uplink of the 3rd PON standard of scheduled standard upstream bandwidth in a variety of PON standards Bandwidth.By the above-mentioned means, upstream bandwidth can be made full use of.

Optionally, a kind of reclaim mechanism of upstream bandwidth is additionally provided in embodiments of the present invention.

For example, OLT detects in a variety of PON standards registered ONU under the scheduled PON standard to standard upstream bandwidth Quantity；The standard upstream bandwidth for the PON standard that the quantity of registered ONU in a variety of PON standards is zero is determined as zero by OLT. By this way, need a certain PON standard is offline from OLT, then only need by under the PON standard ONU all nullify, Then the standard upstream bandwidth that the PON standard is distributed can all be recycled.

In another example quantity of the OLT according to the ONU under every kind of PON standard in a variety of PON standards, determines every kind of PON standard Standard upstream bandwidth includes: that OLT is detected in a variety of PON standards and worked under scheduled the 5th PON standard to standard upstream bandwidth ONU quantity；The standard upstream bandwidth that the quantity of the ONU to work in a variety of PON standards is zero PON standard is determined as by OLT Preset value.By this kind of mode, the ONU under certain PON standard is completely in off-line state, but these ONU are not yet infused on OLT In the case where pin, the upstream bandwidth of a preset value can be only reserved (for example, minimum uplink band needed for carrying out uplink communication It is wide) give these ONU；After ONU is again online, upstream bandwidth is redistributed further according to online ONU, to improve uplink band Wide utilization rate.

Optionally, the access way of uplink and downlink can be determined according to the uplink and downlink wavelength of PON standard, example Such as:

In the case where some or all of overlapping of the upstream wavelength of a variety of PON standards, the ONU of a variety of PON standards is upper Line direction is worked using time division multiplexing mode；And/or

In the case where some or all of overlapping of the downstream wavelength of a variety of PON standards, the ONU of a variety of PON standards is under Line direction is worked using time division multiplexing mode；In the case where the downstream wavelength of a variety of PON standards is mutually underlapped, a variety of PON The ONU of standard is worked in down direction using wave division multiplex mode.

By the above-mentioned means, each ONU sends upstream data, same standard ONU hair in the upstream bandwidth for distributing to oneself The upstream data sent does not conflict mutually, and the upstream data that different systems ONU is sent also does not conflict mutually.

Through the embodiment of the present invention, when needing that the ONU of the 2nd PON standard is online, OLT can according to preset configuration or Person starts bandwidth scheduling center automatically, is that the ONU of the first and second PON standard carries out the distribution of first stage standard upstream bandwidth, the One, the upstream bandwidth distribution function of two PON standards carries out the bandwidth allocation of second stage again, carries out bandwidth point for the ONU under it Match, to receive the registration of the ONU of the 2nd PON standard in the time window for belonging to the 2nd PON standard, completes the 2nd ONU system The ONU's of formula is online.The ONU of first PON standard is being communicated in the standard upstream bandwidth for belonging to the first PON standard with OLT, and The ONU of 2nd PON standard is being communicated in the standard upstream bandwidth for belonging to the first PON standard with OLT, is avoided between different standard Since what is communicated between ONU caused by uplink and downlink overlapping wavelengths influences each other；Also, in the online of the ONU of the 2nd PON standard In the process, the ONU of the first PON standard is without offline.It solves the problems, such as the different standard smooth upgrade that cannot achieve ONU, realizes The different standard smooth upgrade of ONU improves the efficiency of ONU upgrading.

It should be noted that above-mentioned a variety of PON standards can be the standard under identical standard system, it is also possible to difference Standard under standards system.Although the embodiment of the present invention, which is applied, has more preferably effect in the case where different standard upgrades scene, Being upgraded between different systems in identical standard system can also be using scheme provided by the embodiment of the present invention.

A kind of ONU register method is additionally provided in the present embodiment.Fig. 2 is the registration side ONU according to an embodiment of the present invention The flow chart of method, as shown in Fig. 2, the process includes the following steps:

Step S202, in the case where OLT scheduled standard upstream bandwidth to other PON standards, OLT is according to not yet It is dispatched to the quantity of ONU to be registered under the first PON standard of standard upstream bandwidth, determines the first standard of the first PON standard Upstream bandwidth；

Step S204, OLT are the open quiet window of ONU to be registered in the first standard upstream bandwidth；

Step S206, OLT complete the registration of ONU to be registered in quiet window.

Through the above steps, standard upstream bandwidth is not yet dispatched in the first PON standard, and the ONU under the first PON standard It first can be the first PON standard scheduling standard upstream bandwidth according to the quantity of ONU to be registered when being registered on OLT, and Open peace and quiet window solves the different standard that cannot achieve ONU to realize the registration of ONU on the standard upstream bandwidth being dispatched to The problem of smooth upgrade, realizes the different standard smooth upgrade of ONU, improves the efficiency of ONU upgrading.

Optionally, after OLT completes the registration of ONU to be registered in quiet window, OLT then can be in the first standard Upstream bandwidth is distributed in upstream bandwidth for the ONU of the first PON standard.

After OLT distributes upstream bandwidth in the first standard upstream bandwidth for the ONU of the first PON standard, OLT can be more The quantity of the ONU under every kind of PON standard on new OLT in the scheduled PON standard to standard upstream bandwidth and/or ONU's is upper Row flow；OLT is determined every according to the quantity of updated ONU under every kind of PON standard and/or the uplink traffic of updated ONU The kind updated standard upstream bandwidth of PON standard；Updated standard upstream bandwidth is scheduled to corresponding PON standard by OLT.It is logical Which is crossed, real-time, the flexible dispatching of standard upstream bandwidth may be implemented.

Optionally, the quantity of updated ONU includes but is not limited at least one of under every kind of PON standard: every kind of PON Registered ONU under ONU to be registered, every kind of PON standard under the ONU that works under standard, every kind of PON standard.

Optionally, OLT is according to the upstream of the quantity of updated ONU and/or updated ONU under every kind of PON standard Amount, determine in the updated standard upstream bandwidth of every kind of PON standard: OLT can detecte updated under every kind of PON standard infused The quantity of the ONU of volume；The standard upstream bandwidth for the PON standard that the quantity of registered ONU is zero is determined as zero by OLT.Pass through Which realizes the offline of PON standard.

Optionally, OLT determines every kind of PON standard according to the quantity of the ONU under every kind of PON standard in a variety of PON standards In standard upstream bandwidth: OLT can detecte the quantity of the ONU of updated work under every kind of PON standard；OLT is by the ONU of work Quantity be zero the standard upstream bandwidth of PON standard be determined as preset value.By this way, the utilization of upstream bandwidth is improved Rate.
