Technical field

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

Background technology

With the fast development of broadband services, user increases substantially to the demand of access network bandwidth, EPON (Passive Optical Network, referred to as PON) is a kind of important technical that current user accesses.PON System is generally 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 the OLT of point-to-multipoint structure, i.e., and connects Meet multiple ONU.Usual OLT is down direction to ONU, and ONU is up direction to OLT.

By a wavelength to communicating, OLT opens peace and quiet window and asks OLT and ONU in downstream wavelength The identity information of ONU, after ONU reports that identity information, OLT obtain the identity information of ONU in upstream wavelength, Peace and quiet window is opened in downstream wavelength again and distance measurement request is sent, ONU replies ranging response in upstream wavelength, OLT completes range finding, and OLT sends data according to downlink business situation to ONU, and according to the uplink service feelings of ONU The bandwidth request of condition or ONU is ONU distribution bandwidths, and ONU sends upstream data in the bandwidth for distributing to oneself.

Global operator deployed gigabit passive optical network (Gigabit PON, referred to as GPON), ether without Source optical-fiber network (Ethernet PON, referred to as EPON).In order to lift user's access bandwidth, operator needs to dispose band Ten gigabit passive optical networks (10Gigabit PON, referred to as XG-PON1) higher wide, ten gigabit ether without Source optical-fiber network (10Gigabit EPON, referred to as 10GEPON) etc..In these technologies, GPON, XG-PON1 International Telecommunication Union's telecommunication standardsization tissue (ITU-T) standards system is belonged to, EPON, 10GEPON are belonged to together In Institute of Electrical and Electric Engineers (IEEE) standards system, with the PON technologies of standards system in standard formulation process In, the demand of upgrading evolution has been taken into full account, or physical layer, protocol layer compatibility are relatively by force, or tailor The scheme of upgrading evolution, therefore PON technology upgrading evolution with standards system is easier to, and upgrading evolution process In the ONU of normal work tried one's best accomplish that influence is minimum.For example, GPON and XG-PON1 under ITU-T standard system Using entirely different up-downgoing wavelength, after a GPON ONU is substituted for XG-PON1ONU, because up-downgoing Wavelength there occurs change, naturally be linked into XG-PON1OLT, will not be to other ONU under GPON OLT Have an impact.

Specific embodiment

Describe the present invention in detail below with reference to accompanying drawing and in conjunction with the embodiments.It should be noted that in the feelings not conflicted Under condition, the feature in embodiment and embodiment in the application can be mutually combined.

It should be noted that term " first ", " second " in description and claims of this specification and above-mentioned accompanying drawing Etc. being for distinguishing similar object, without for describing specific order or precedence.

A kind of bandwidth scheduling method is provided in the present embodiment, and Fig. 1 is bandwidth scheduling method according to embodiments of the present invention Flow chart, as shown in figure 1, the flow comprises the following steps：

The quantity and/or ONU of step S102, OLT according to the ONU under every kind of PON standards in various PON standards Uplink traffic, determine the standard upstream bandwidth of every kind of PON standards；

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

By above-mentioned steps, coexist or need under the scene for coexisting in various PON standards, be every kind of PON by OLT Standard determines standard upstream bandwidth, and the upstream bandwidth of determination is scheduled into these PON standards respectively.Due to each PON Standard has been scheduled respective upstream bandwidth, therefore the bandwidth allocation function of each PON standard can be arrived according to scheduled Standard upstream bandwidth, further be under the standard ONU distribution upstream bandwidth, it is achieved thereby that various PON standards ONU coexist.Using above-mentioned steps provided in an embodiment of the present invention, the up band in realizing to ODN networks Adaptive scheduling with PON standards wide, solves the problems, such as that the different standard smooth upgrade of ONU cannot be realized, realizes The different standard smooth upgrade of ONU, improves the efficiency of ONU upgradings.

It is signified standard upstream bandwidth in the embodiment of the present invention, up it should be noted that in the case of wavelength-division multiplex With a width of upstream wavelength；In the case of time division multiplexing, standard upstream bandwidth, up band signified in the embodiment of the present invention The duration of a width of use upstream wavelength.

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

After the standard upstream bandwidth that different PON standards are realized by above-mentioned steps is distributed, the band of each PON standard Distribution function wide then can distribute upstream bandwidth for respective ONU.To be many in OLT by taking a PON standards as an example Individual standard upstream bandwidth is scheduled to after corresponding PON standards respectively, OLT the scheduling of the first PON standards is obtained the One standard upstream bandwidth distributes to the ONU of a PON standards.

Distribution to the upstream bandwidth of ONU, since the registration of ONU.Alternatively, by taking a PON standards as an example, OLT is opened according to preset configuration or user instruction, the ONU for a PON standards in the first standard upstream bandwidth Put quiet window；OLT detects the up log-on message of the ONU of a PON standards in quiet window；In detection To the ONU of a PON standards up log-on message in the case of, OLT complete a PON standards ONU Registration；OLT is the ONU distribution upstream bandwidths of a PON standards in the first standard upstream bandwidth.By this Mode, realizes the registration of ONU, and after ONU is registered on OLT, for the ONU is assigned with up band It is wide.Wherein, in open peace and quiet window, preset configuration can be set for quiet window is opened in timing；Can also need The user instruction of open peace and quiet window is sent when registering new ONU to OLT, the letter of peace and quiet window is carried in user instruction Breath, for example：Open duration, wavelength etc..

Above-mentioned preset configuration refers to：The configuration information that user writes according to demand, these configuration informations are used to indicate OLT According to bandwidth scheduling center distribute belong in a kind of standard upstream bandwidth of PON standards, the suitable time or with Predetermined frequency opens the time window of scheduled duration, to receive this kind of registration of the ONU of PON standards, and further The data that normal work sends.

Alternatively, after having new ONU to be registered on OLT, then it is registered on OLT under corresponding PON standards The quantity of ONU will change.Now, under some strategies, can be to the standard upstream bandwidth of correspondence PON standards Redefined and dispatched.For example：The number of the ONU in the various PON standards of OLT renewals under every kind of PON standards The uplink traffic of amount and/or ONU；Quantity and/or renewal of the OLT according to the ONU after being updated under every kind of PON standards The uplink traffic of ONU afterwards, determines the standard upstream bandwidth after every kind of PON standards renewal；OLT is by after renewal Standard upstream bandwidth is scheduled to corresponding PON standards.Through the above way, it is possible to achieve the registration scenarios of ONU, by One is the PON standards increase standard upstream bandwidth where each ONU, realizes the registration one by one of ONU and up band Adaptive scheduling wide.

In embodiments of the present invention, after being updated under the quantity or every kind of PON standards of the ONU under every kind of PON standards The quantity of ONU include but is not limited at least one of：ONU, the every kind of PON worked under every kind of PON standards Registered ONU under ONU to be registered, every kind of PON standards under standard.By this way, can flexibly set The strategy of bandwidth scheduling, adapts to various scene demands.

Alternatively, a kind of ONU for being worked under PON standards and/or ONU to be registered and/or registered ONU And/or the uplink traffic of ONU is bigger, then the standard upstream bandwidth that this PON standards are scheduled for will be bigger.

Alternatively, upstream bandwidth can disposably be assigned, it is also possible to according to some cycles dynamically distributes.Due to up Total bandwidth is probably fixed；When the adaptive scheduling of upstream bandwidth is carried out, can reserve a part of upstream bandwidth is used for Self-adjusted block gives each PON standard.

For example, in the presence of in two kinds of ODN 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, the first PON There is ONU to nullify under standard, there is new ONU to register under second PON standard；At this point it is possible to by the up band of standard A1 wide is reduced or is kept constant, increases standard upstream bandwidth A2；The increased parts of standard upstream bandwidth A2 are reserved The part that a part, or standard upstream bandwidth A1 of upstream bandwidth B is reduced.Using this kind of mode, can be with So that the standard upstream bandwidth distributed between each standard increases or reduces independently of each other, upstream bandwidth scheduling is reduced Computation complexity.Disadvantage is that reserving a part of upstream bandwidth.May result in the idle wave of part upstream bandwidth Take.

When the adaptive scheduling of upstream bandwidth is carried out, it is also possible to do not reserve upstream bandwidth.

For example, OLT determines not yet to be dispatched to the second of the 2nd PON standards of standard upstream bandwidth in various PON standards Standard upstream bandwidth；OLT adjusts the 3rd of the 3rd PON standards of scheduled standard upstream bandwidth in various PON standards Standard upstream bandwidth.Through the above way, upstream bandwidth can be made full use of.

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

For example, registered under the scheduled PON standards to standard upstream bandwidth in the various PON standards of OLT detections The quantity of ONU；OLT is by the standard of PON standards that the quantity of registered ONU in various PON standards is zero Row bandwidth is defined as zero.By this way, needing a certain PON standards is offline from OLT, then only needing to this ONU under PON standards is all nullified, then the standard upstream bandwidth that can be distributed the PON standards is all reclaimed.

Again for example, OLT determines every kind of PON according to the quantity of the ONU under every kind of PON standards in various PON standards The standard upstream bandwidth of standard includes：It is scheduled to the 5th of standard upstream bandwidth in the various PON standards of OLT detections The quantity of the ONU worked under PON standards；The quantity of the ONU worked in various PON standards is zero PON by OLT The standard upstream bandwidth of standard is defined as preset value.By this kind of mode, the ONU under certain PON standard is completely in Off-line state, but these ONU can only reserve a up band for preset value not yet in the case of cancellation on OLT (for example, the minimum upstream bandwidth needed for carrying out uplink communication) wide gives these ONU；After ONU reaches the standard grade again, then Upstream bandwidth is redistributed according to online ONU, so as to improve the utilization rate of upstream bandwidth.

Alternatively, the access way of uplink and downlink can determine according to the uplink and downlink wavelength of PON standards, example Such as：

In the case of some or all of overlap of upstream wavelength of various PON standards, the ONU of various PON standards Worked using time division multiplexing mode in up direction；And/or

In the case of some or all of overlap of downstream wavelength of various PON standards, the ONU of various PON standards Worked using time division multiplexing mode in down direction；In the case where the downstream wavelength of various PON standards is mutually underlapped, The ONU of various PON standards is worked in down direction using wave division multiplex mode.

Through the above way, each ONU sends upstream data, same standard ONU in the upstream bandwidth for distributing to oneself The upstream data of transmission does not conflict mutually, and the upstream data that different systems ONU sends also does not conflict mutually.

By the embodiment of the present invention, when needing to reach the standard grade the ONU of the 2nd PON standards, OLT can be according to default Configuration or automatic bandwidth scheduling center, are that to carry out first stage standard up for the ONU of first and second PON standards Bandwidth allocation, the upstream bandwidth distribution function of first and second PON standards carries out the bandwidth allocation of second stage again, is it Under ONU carry out bandwidth allocation, so as in the time window for belonging to the 2nd PON standards receive the 2nd PON standards ONU registration, the ONU for completing the 2nd ONU standard reaches the standard grade.The ONU of the first PON standards is belonging to Communicated with OLT in the standard upstream bandwidth of the first PON standards, and the ONU of the 2nd PON standards is belonging to first Is communicated with OLT in the standard upstream bandwidth of PON standards, it is to avoid led due to up-downgoing overlapping wavelengths between different standard What is communicated between the ONU of cause influences each other；Also, during the reaching the standard grade of ONU of the 2nd PON standards, first The ONU of PON standards is without offline.Solve the problems, such as to realize the different standard smooth upgrade of ONU, realize The different standard smooth upgrade of ONU, improves the efficiency of ONU upgradings.

It should be noted that above-mentioned various PON standards can be standard under identical standard system, or not With the standard under standards system.Although the embodiment of the present invention is applied has more excellent effect under different standard upgrading scene, It is that the scheme that upgrading can also be provided using the embodiment of the present invention is carried out between the different systems in identical standard system.

A kind of ONU register methods are additionally provided in the present embodiment.Fig. 2 is ONU notes according to embodiments of the present invention The flow chart of volume method, as shown in Fig. 2 the flow comprises the following steps：

Step S202, in the case where OLT scheduled standard upstream bandwidth to other PON standards, OLT roots According to the quantity for being not yet dispatched to ONU to be registered under a PON standards of standard upstream bandwidth, a PON is determined First standard upstream bandwidth of standard；

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

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

By above-mentioned steps, standard upstream bandwidth is not yet dispatched in a PON standards, and under a PON standards When ONU will be registered on OLT, can be according to the quantity of ONU to be registered first for a PON standards dispatch standard Upstream bandwidth, and the open peace and quiet window on the standard upstream bandwidth being dispatched to, to realize the registration of ONU, solve The problem of the different standard smooth upgrade of ONU cannot be realized, the different standard smooth upgrade of ONU is realized, ONU is improved The efficiency of upgrading.

Alternatively, after the registration that OLT completes ONU to be registered in quiet window, OLT then can be first It is the ONU distribution upstream bandwidths of a PON standards in standard upstream bandwidth.

After OLT is in the first standard upstream bandwidth for the ONU distribution upstream bandwidths of a PON standards, OLT The number of the ONU under the every kind of PON standards on OLT in the scheduled PON standards to standard upstream bandwidth can be updated The uplink traffic of amount and/or ONU；Quantity and/or renewal of the OLT according to the ONU after being updated under every kind of PON standards The uplink traffic of ONU afterwards, determines the standard upstream bandwidth after every kind of PON standards renewal；OLT is by after renewal Standard upstream bandwidth is scheduled to corresponding PON standards.By this way, it is possible to achieve standard upstream bandwidth it is real-time, Flexible dispatching.

Alternatively, the quantity of the ONU after being updated under every kind of PON standards includes but is not limited at least one of：It is every kind of It is registered under ONU, every kind of PON standards to be registered under the ONU, the every kind of PON standards that are worked under PON standards ONU。

Alternatively, OLT is according to the upper of the ONU after the quantity of the ONU after being updated under every kind of PON standards and/or renewal Row flow, determine every kind of PON standards update after standard upstream bandwidth in：OLT can be detected under every kind of PON standards The quantity of the registered ONU after renewal；OLT is by the standard of PON standards that the quantity of registered ONU is zero Upstream bandwidth is defined as zero.By this way, the offline of PON standards is realized.

Alternatively, OLT determines every kind of PON according to the quantity of the ONU under every kind of PON standards in various PON standards In the standard upstream bandwidth of standard：OLT can detect the quantity of the ONU of the work after updating under every kind of PON standards； The standard upstream bandwidth of the PON standards that the quantity of the ONU of work is zero is defined as preset value by OLT.By the party Formula, improves the utilization rate of upstream bandwidth.
