Embodiment
Below in conjunction with drawings and Examples, embodiments of the present invention are described further.
A kind of core concept of configuration distributing method is among the present invention: in the PON network of considering in reality, the applied service of user is relatively more fixing relatively, therefore the configuration of most of ONU all is similar, therefore can in advance the identical ONU of configuration be divided in the group, configuration and configuration distributing for ONU all are that unit carries out with the group, thereby solve the resource cost that the loaded down with trivial details and system that disposes issues configuration.
A kind of configuration distributing method may further comprise the steps as shown in Figure 3 among the present invention:
Group under the ONU that step s101, OLT determine to succeed in registration is also added this ONU in group membership's tabulation that preserve this locality.
The PON chip of each PON mouth of OLT when OLT registers, distributes LLID (Logical Link Identifier, LLID) to ONU at ONU.Wherein the PON chip of each PON mouth is safeguarded the LLID that oneself distributes, and the LLID that same PON mouth distributes can not repeat.Simultaneously, can be on OLT according to each PON chip ability, divide the logic port of a plurality of ONU for the PON mouth of each OLT, each logic interfacing can insert an ONU.The corresponding relation of this logic interfacing and ONU can be bound when network configuration in advance, specific logic interfacing is distributed to specific ONU, for example with MAC (the Medium Access Control of logic interfacing and ONU, the medium access control) bind the address, or according to the business that ONU asked the ONU dynamic assignment is arrived specific logic interfacing.
Therefore for the OLT of many PON mouth, for each ONU is carried out unique identification, the group data structure of the ONU that OLT preserves in group membership's tabulation of this locality should comprise at least: the port-mark of ONU and the LLID of ONU.Wherein the port-mark of ONU is the logical port number of ONU, or when the MAC Address binding of the logic port of ONU and ONU, also can use the port-mark of the MAC Address binding of ONU as ONU, also can according to the MAC Address of ONU obtain the logical port number of ONU by binding relationship this moment.
With the port-mark of ONU is that the logical port number of ONU is an example, and at this moment, the group data structure of the ONU that OLT preserves in group membership's tabulation of this locality comprises the logical port number of ONU and the LLID of ONU.Wherein, the logical port number of ONU is corresponding to the PON mouth of OLT, and for example the PON mouth of OLT is represented with Pn, and each Pn comprises the logic port of a plurality of ONU, and then the logic port of ONU can be represented with Pn.m; The LLID of ONU is the LLID of the PON chip of ONU registration back OLT for its distribution.After the ONU registration, the LLID of this ONU is corresponding with the logic port of this ONU, thus each ONU unique identification that will insert OLT comes out.
Based on foregoing description, for the ONU group of each configuration, OLT can set up the member ONU information table of a shape such as table 1:
Table 1: member ONU information table:
| ONU logic port ID | The LLID of the ONU that OLT distributes |
For unified management, can be the form shown in the table 2 with the employed above-mentioned member ONU information table storage and uniform of different groups:
Table 2:ONU group membership tabulation:
| Group ID | ONU logic port ID | The LLID of the ONU that OLT distributes |
Table 2 is with the difference of table 1, has increased group ID item, for different groups, can directly be stored in the form and according to group ID and distinguish.Below be that example is described with the form of table 2 in each step with ONU group membership tabulation, simultaneously for convenience of description for the purpose of, with the list item in the table 2 with (group ID, ONU logic port ID, the LLID of the ONU that OLT distributes) expression.
Which kind of mode step s102, OLT judgement is adopted to dispose to OLT and is issued, and carries out step s103 when adopting mode of unicast, carries out step s105 when adopting broadcast mode.
In this step, OLT can select to dispose the mode that issues to OLT, and different modes is applicable to different scenes.
Concrete, mode of unicast is meant that OLT only issues configuration to certain specific ONU, can take this mode at new ONU after finishing registration, authentication on the OLT; Or be applied to the configuration restore of the ONU that starts in the PON system normal course of operation.
Concrete, broadcast mode is meant that OLT will issue configuration to a plurality of ONU simultaneously, when unification is configured OLT after the PON system topological is put up; Or when needing to restart OLT after the OLT system hardware and software upgrading, all can use broadcast mode to issue configuration.This mode can be utilized a broadcasting LLID (0x7FFF) who stipulates in MPCP (Multi-point controlprotocol, the Multi-point Control Protocol) agreement, simultaneously all ONU is issued configuration.
Step s103, OLT adopt mode of unicast to issue configuration to specific ONU.
OLT is according to this information of purpose ONU in ONU group membership tabulation that issues configuration, and the PON mouth to this specific ONU place issues configuration.This configuration that issues need encapsulate according to the MPCP agreement, carries the LLID of this purpose ONU in the process of encapsulation.
Step s104, ONU handle this message according to the LLID in the message and finish.
All ONU under the PON mouth at this specific ONU place can receive the message that this carries configuration.Whether ONU can discern by the LLID that message carries when receiving message is the message of oneself, if then receive this configuration and issue in this locality, if not then abandoning.Therefore according to the LLID that carries in the message, the specific ONU that only has this LLID just can handle this message.Thereby realized configuration distributing to specific ONU.
Step s105, OLT adopt broadcast mode to issue configuration to a plurality of ONU.
OLT need give when a plurality of members issue configuration in the group, according to the difference of member place PON mouth, for the different message that carries broadcasting LLID of each PON mouth configuration.For each specific PON mouth, with configuration information and the identification information that is used for distinguishing the group membership be encapsulated in message, and issue to this PON mouth after in message, adding broadcasting LLID.
Step s106, ONU handle this message according to the identification information in the message and finish.
At this moment, the broadcasting LLID that all ONU under this specific PON carry according to this message, this carries the message of configuration all can to receive processing.Further, each ONU judges according to the identification information that is used to distinguish the group membership that carries in this message whether self belongs to this group, then receives this configuration and issues in this locality if belong to, otherwise abandon.Concrete, this identification information that is used to distinguish the group membership can be group membership LLID tabulation or group id.
Application scenarios below in conjunction with concrete is further described embodiments of the present invention.
At first adopting mode of unicast to issue to specific ONU with OLT is configured to example, describes the method for a kind of configuration distributing among the present invention.
Suppose a certain moment in the PON system normal course of operation, the ONU1 that the PON mouth P1 of OLT exists down starts, professional or according to this ONU asked according to the MAC Address of pre-configured ONU and the binding relationship of logic port, the logic port of ONU1 is assigned as adds the logic port P1.10 that organizes G1.Tabulate to the structure shown in the last table 2 as if the ONU group membership,, in initial ONU group membership tabulation is answered, comprise following list item then for this ONU1: (G1, P1.10), wherein the LLID of the ONU of OLT distribution temporarily is empty.
When ONU1 after registration on the OLT is finished, suppose that OLT is 0x001E (30 in corresponding 10 systems) for the LLID of this ONU1 distribution; Then the list item in the ONU group membership tabulation is changed to: (G1, P1.10,0x001E).
After registration is finished, OLT need issue configuration to ONU1, then OLT constructs OAM (OperationsAdministration and Maintenance, Operations,Administration And Maintenance) message carries the configuration about group G1 that need issue to ONU1, and this message is issued to the PON chip of the PON mouth P1 at ONU1 place according to the ONU group membership tabulation of preserving.The PON chip of P1 carries out the MPCP protocol encapsulation to this message, and the LLID of interpolation ONU1 is 0x001E in the message of encapsulation.After this message was issued to all ONU under the P1, having only LLID was that the ONU1 of 0x001E can handle this message, and the configuration information that message carries is issued to this locality.
By said process, realized that OLT adopts mode of unicast to issue configuration to specific ONU.
Below adopt broadcast mode to issue with OLT to be configured to example, to describe the method for a kind of configuration distributing among the present invention to specific ONU.
Suppose to exist in the ONU group membership tabulation of OLT following list item:
The list item of ONU1: (G1, P1.10,0x001E);
The list item of ONU2: (G1, P1.20,0x001F);
The list item of ONU3: (G1, P2.10,0x001E);
The list item of ONU4: (G2, P2.20,0x001D).
In certain moment, OLT need organize specific being configured to for unit issues to specific group, is example to issue to group G1, can adopt following several broadcast mode to issue ONU1 from configuration to group G1 and ONU2:
Mode one:
OLT determines that according to the logic port information of ONU among the group G1 ONU1 and the ONU2 among the group G1 is positioned under the P1 mouth, and ONU3 is positioned under the P2 mouth.Then OLT will organize the configuration information of G1 and group membership LLID tabulation (LLID that comprises ONU1 and ONU2 here) and be packaged in the message together and carry broadcasting LLID, and afterwards, OLT issues this message to the P1 mouth; Simultaneously, configuration information and group membership LLID tabulation (LLID that comprises ONU3 here) that OLT will organize G1 are packaged in the message together, and carry broadcasting LLID, and afterwards, OLT issues this message to the P2 mouth.
When all ONU under the P1 mouth received this message, the broadcasting LLID that carries according to this message was judged as and receives this message, and whether comprised the LLID of oneself in the group membership LLID tabulation of further carrying in this message.For ONU1 and ONU2, judged result is the LLID that comprises oneself, then issues and is configured to this locality; For the ONU under other P1 mouths, judged result illustrates oneself not add this group for not comprising the LLID of oneself, abandons this message.
For all ONU under the P2 mouth, processing method has only ONU3 to issue and is configured to this locality with the processing method of all ONU under the P1 mouth, and this process is not described further at this.
Mode two:
After each ONU registration, OLT sends to ONU with the group ID under this ONU by mode of unicast, and it belongs to group G1 for example to send message informing to ONU1, ONU2 and ONU3, and it belongs to the G2 group to send message informing to ONU4.
Afterwards, OLT need needn't carry ONU group membership tabulation with specific configuration when group G1 issues, get final product and only have group ID.Be that configuration information and the group ID (here for group G1) that OLT then will organize G1 issues to P1 mouth and P2 mouth.
After ONU under the P1 mouth receives broadcasting LLID message, further or get its group ID that carries and local group ID contrast of preserving.For the message that carries group G1 sign, it is identical with the group ID of local preservation that ONU1 and ONU2 are judged as the group ID that message carries, and issues configuration set in this locality; It is different with the local group ID that preserves that other ONU under the P1 mouth are judged as the group ID that message carries, and abandons this message.
For all ONU under the P2 mouth, processing method has only ONU3 to issue and is configured to this locality with the processing method of all ONU under the P1 mouth, and this process is not described further at this.
By above-mentioned dual mode, realized that OLT adopts broadcast mode to issue configuration to specific ONU.
In addition, when after OLT is restarted, carrying out the configuration distributing of broadcast mode, because the situation that causes part group membership ONU also not succeed in registration before configuration distributing successively, may appear in the sequential of ONU registration, causes disposing and can't issue to these unregistered successful ONU.Therefore must there be interior each member of corresponding machine-processed assurance group can receive the configuration distributing message of group.Solution to the problems described above is: receive to postpone a period of time behind first member's logon message in the group (for example: the configuration set of 1s) broadcasting again issues.Consider to require the ONU of the EPON system hour of log-on should be less than 20ms in the prior art, the ONU registration process of therefore actual PON system be relatively short, and delay sending can assurance be organized most of member can finish configuration restore in broadcasting configuration set link.All the other group memberships that do not finish before the broadcasting configuration set carry out the configuration restore of unicast mode again.The method of this broadcasting, clean culture combination has been taken into account high efficiency and reliability.
The method that the application of the invention the foregoing description provides, identical ONU is divided in the group in advance with configuration, and is unit with the group all for configuration and the configuration distributing of ONU, has reduced the configuration file size, saves the memory space of system; In addition, the ONU configuration distributing time in the time of can shortening system upgrade effectively, saved system resource, reduced service disconnection.
