Embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
EPON system requirements is supported the CTC of China Telecom protocol suite at present, CHINAUNICOM's protocol suite, the multiple OAM protocol suites such as the DPOE protocol suite of U.S. Cablabs, and in prior art for how to switch between multi-protocols collection, and in the time that system is used certain protocol suite, how adopting other protocol suite to operate etc. not yet has effective solution, for above problem, the invention provides the method for multiple OAM protocol suite compatibility in a kind of EPON of realization system, can support under the pattern of multiple OAM protocol suite in EPON system, realize multiple OAM protocol suite switching and compatible, various protocols stack can and be deposited on the OLT of an EPON system and dynamic load.
Particularly, as shown in Figure 1, the invention provides a kind of method that realizes multiple OAM protocol suite compatibility, for supporting the EPON system of multiple OAM protocol suite, described EPON system comprises optical line terminal OLT, optical network unit ONU and Optical Distribution Network ODN, and described method comprises:
In the time that optical network unit ODU reaches the standard grade, optical line terminal OLT is expanded to OAM and consult, obtain organization unique identifier OUI;
Whether inquiry optical line terminal OLT has been configured to support an OAM protocol suite of appointment;
In the time being configured to support an OAM protocol suite of appointment in optical line terminal OLT, optical line terminal OLT is adopted a described OAM protocol suite, as current OAM protocol suite, optical network unit ONU is carried out to OAM management;
In the time not being configured to support an OAM protocol suite of appointment in optical line terminal OLT, optical line terminal OLT is adopted the 2nd OAM protocol suite of described organization unique identifier OUI association, as current OAM protocol suite, optical network unit ONU is carried out to OAM management.
In the present invention, which kind of OAM protocol suite the OLT that configures EPON system by newly-increased order line supports, such as: on OLT, create an order, this command specifies OLT adopts the one in the OAM protocol suites such as CTC, DPOE, CUN, default value is ALL, adopts DPOE protocol suite, so as created command specifies OLT on OLT, EPON system is carried out this order, adopts DPOE protocol suite; And if the OLT of EPON system need to adopt other OAM protocol suite, as CTC protocol suite,, by create order on the OLT of EPON system, this command specifies OLT adopts CTC protocol suite, and so, EPON system carries out this order, switches and adopts CTC protocol suite; And in the time not configuring by order line on OLT or be configured to default value ALL, OLT, in the time that ONU reaches the standard grade, consults by expansion OAM, obtain and organize uniquely tagged symbol OUI, EPON system adopts the OAM protocol suite associated with organizing uniquely tagged symbol OUI.
By above-mentioned processing, EPON system is configured and is identified the organization unique identifier OUI that expansion OAM consults and realizes switching and the compatibility of multiple OAM protocol suite by order line, various protocols stack can and be deposited on the OLT of an EPON system; And, due to the OAM protocol suite type that adopts order line configuration OLT to support, can load the OAM protocol suite type that OLT supports by newly-increased order line, realize the dynamic load of OAM protocol suite in EPON system.
In addition, for OAM protocol stack compatible design, in the present invention, optical line terminal OLT adopts current OAM protocol suite optical network unit to be carried out in the process of OAM management, if when current OAM protocol suite is not supported an OAM bookkeeping of the appointment that OLT issues OUN, optical line terminal adopts default OAM protocol suite or specifies OAM protocol suite for subsequent use to carry out a described OAM bookkeeping.
By above-mentioned processing, certain property operations of the OAM that issues for OLT management, if current OAM protocol suite do not support, attempt using popular protocol collection to carry out this operation.Popular protocol collection refers to default OAM protocol suite or specifies OAM protocol suite for subsequent use.
Below in conjunction with accompanying drawing, describe a kind of embodiment of the present invention in detail.
As shown in Figure 4, realize in the method for multiple OAM protocol suite compatibility in EPON system of the present invention, specifically comprise the following steps:
OLT and ONU are connected to each other, and in the time that ONU reaches the standard grade, by expansion, OAM consults, and determines organization unique identifier OUI;
Whether inquiry specifies by order line a kind of OAM protocol suite of supporting in multiple OAM protocol suite on OLT, if, EPON system is carried out this order, adopts the OAM protocol suite (as DPOE protocol suite) of this appointment as current OAM protocol suite, and preserves corresponding scripts;
If OLT order line does not configure or be configured to default value ALL, EPON system adopts the OAM protocol suite of definite organization unique identifier OUI association through consultation as current OAM protocol suite;
The above-mentioned current OAM protocol suite that employing chooses carries out adaptation;
The current OAM protocol suite adopting at OLT is not popular protocol collection, and the current OAM protocol suite that OLT adopts is in the time carrying out certain property operations, if current OAM protocol suite is not supported this property operations, attempt with popular protocol collection stack, as stack for subsequent use, carrying out this property operations;
The current OAM protocol suite adopting as OLT is popular protocol collection, and the current OAM protocol suite that OLT adopts is in the time carrying out certain property operations, if current OAM protocol suite is not supported this property operations, directly returns to mistake.
It should be noted is that, in method of the present invention, no matter adopt which kind of OAM protocol suite, for each OAM management attribute operation, the script generating is all consistent with telemanagement data, can not cause because adopted OAM protocol suite is different the script and the inconsistent problem of telemanagement data that generate.In addition, in method of the present invention, there is respectively an adaptation layer in each OAM protocol suite, 0-1 alignment problem and the protocol fields inconsistence problems of adaptive each the OAM protocol suite of this adaptation layer.
A kind of equipment of realizing multiple OAM protocol suite compatibility is also provided in the present invention, and for supporting the EPON system of multiple OAM protocol suite, described EPON system comprises optical line terminal, optical network unit and Optical Distribution Network, and described equipment comprises:
