Abstract
The invention provides a method and device for configuring an optical network system and the optical network system. The method for configuring the optical network system is applied to the optical network system with at least one OLT managing multiple ONUs. The OLT comprises multiple PON chips and an ONU configuration module for issuing ONU tasks to the PON chips. The method includes the steps that the ONU configuration module sequentially issues each configuration item independently; after each configuration item is issued, an application layer module calls interfaces of a driving layer; the driving layer issues the issued configuration items in parallel to the ONUs in the optical network system. By the adoption of the technical scheme, each configuration item is issued independently, the issued configuration items are issued by the driving layer in parallel to all the ONUs, and therefore the configuration speed of the ONUs is increased.

Embodiment
As described in the background art, existing ONU configuration restore speed is excessively slow.Inventor is through research: cause ONU configured rate to mainly contain the reason of two aspects slowly.Be ONU Configuration Manager when performing a normally each ONU of poll, then issues all configurations; Another is that all configuration can only walk a collocation channel at driving layer, that is can only execute and could perform next PON mouth by a PON mouth at every turn, and all configurations of each PON mouth next one ONU execute the configuration that could perform next ONU.If ONU number ratio is more and quantity that is needs configuration is also very many, so, can only performs singly, so just considerably increase the time that configuration restore uses, have impact on configuration restore and obtain speed.
For the problems referred to above, the mode that the present invention adopts two modules to combine is optimized, ONU under ONU Configuration Manager adopts poll configuration item to be handed down to all PON mouths, layer is driven to adopt the much channel communication of each PON mouth collocation channel to be configured, such two modules are all to this has been optimization, effect after combining will be optimized relatively, thus the configuration restore of raising ONU full configuration obtains speed.
For enabling above-mentioned purpose of the present invention, feature and advantage more become apparent, and are described in detail specific embodiments of the invention below in conjunction with accompanying drawing.
Fig. 1 shows the schematic flow sheet of the collocation method of a kind of optical network system of the present invention.With reference to figure 1, the collocation method of described optical network system comprises:
Step S1, every configuration item issues separately by described ONU configuration module successively;
Step S2, application layer module, after every configuration item issues, calls the interface driving layer;
Step S3, drives layer to be walked abreast by every the configuration item issued the ONU be issued in described optical network system.
Particularly, the step that every configuration item carries out separately issuing by described Configuration Manager successively comprises:
To reach the standard grade process call back function at ONU configuration module registration ONU;
ONU configuration module travel through successively every configuration item, each PON slogan and each No. ONU to realize issuing successively of every configuration item.
In a particular embodiment, described ONU configuration module can travel through every configuration item, each PON slogan and each No. ONU respectively by three for circulation.
Correspondingly, described driving layer is that each PON mouth configures corresponding socket passage and issues to realize the parallel of every configuration item.
In the collocation method of optical network system provided by the invention, single channel is optimized for many socket passage and serial is optimized for executed in parallel by the mode utilizing socket to communicate, and in conjunction with the order of ONU Configuration Manager to ONU configuration distributing, realize improving the ability of multiple configuration restores of multiple ONU, so just greatly improve the configuration restore speed of ONU, save the reboot time of optical network system.
Fig. 2 shows the schematic diagram of a specific embodiment of the collocation method of optical network system of the present invention.With reference to figure 2, show optical network system detailed process to ONU recovery configuring when restarting in the present embodiment.
Particularly, first register ONU reach the standard grade process the configuration of call back function to ONU recover; Then, by three layers of for circulation, each configuration item of traversal ONU, then travel through PON slogan and finally travel through each ONU; Then, the configuration interface driving layer is called, for each PON mouth configures a socket collocation channel, to realize the parallel deployment to each ONU.
The present embodiment is in 8EPON system, when restarting OLT or ONU to the configuration restore of full configuration ONU, efficiency is replied in many ONU full configuration configuration that the method combined by application layer and driving layer optimizes OLT system, first be that ONU Configuration Manager is optimized for traversal every configuration item to process the ONU under all PON mouths, be exactly often configure a configuration item to be handed down to each ONU under all PON mouths, an ONU need not be waited to configure and just can carry out the next one; Its suboptimization driving layer module is the multichannel of each PON mouth passage by original single channel, combine like this and just can the configuration under 8 PON perform simultaneously, do not need can only to perform by single PON mouth as original, the configuration of other PON mouths performs waits for that previous PON mouth executes and could perform.Doing like this is obviously that serial operation by original is optimized for parallel work-flow, substantially increases the speed of configuration restore, decreases the time of whole OLT system configuration restore.
It should be noted that, the situation of 8 PON mouths has been shown in Fig. 2, but this does not limit protection scope of the present invention, in other embodiments, can also arrange the quantity of PON mouth according to actual needs.
Correspondingly, the present invention also provides a kind of inking device of optical network system, and with reference to figure 3, the inking device of described optical network system can comprise:
ONU configuration module 10, for issuing every configuration item separately successively;
Application layer module 20, for after every configuration item issues, calls the interface driving layer;
Drive layer 30, every configuration item for issuing walks abreast the ONU be issued in described optical network system.
Concrete, described ONU configuration module can comprise: registering unit and Traversal Unit.Described registering unit to be reached the standard grade process call back function for registering ONU; Described Traversal Unit, for travel through successively every configuration item, each PON slogan and each No. ONU to realize issuing successively of every configuration item.
In a particular application, described Traversal Unit can be circulated by for and travel through every configuration item, each PON slogan and each No. ONU.Described driving layer is that each PON mouth configures corresponding socket passage and issues to realize the parallel of every configuration item.
Correspondingly, the present invention also provides a kind of optical network system, and described system comprises: at least one OLT; The multiple ONU be connected with each OLT; And the inking device of aforesaid optical network system.
In technical scheme of the present invention, on the one hand by every configuration item being issued to separately in all ONU successively to ONU configuration module, optimize driving layer on the other hand, the configuration item issued can be walked abreast carry out, thus substantially increase the configured rate of ONU, save the reboot time of system.
Although the present invention discloses as above, the present invention is not defined in this.Any those skilled in the art, without departing from the spirit and scope of the present invention, all can make various changes or modifications, and therefore protection scope of the present invention should be as the criterion with claim limited range.
