Description
Technical field
The present invention relates to a kind of PON(passive optical network) method that communication is realized in equipment, more particularly to a kind of rack
AgentX(extension agency is utilized in formula and frame PON equipment) realize the method communicated.
Background technique
Traditional SNMP(Simple Network Management Protocol, Simple Network Management Protocol) act on behalf of quilt
Referred to as one chip is acted on behalf of, without scalability, some management objects pre-defined of management that can only be fixed, and cannot be in pipe
Addition, deletion management object during reason operation.If the management object of managed network physically changes, it is with regard to necessary
It redesigns to realize that managed network physically manages the variation of content.
AgentX meets above-mentioned requirements, it is made of two class processing routines: a primary proxy and one or more son
Agency.Primary proxy follows AgentX and snmp protocol, it is responsible for safeguarding a table to provide sub-agent and its responsible MIB(pipe
Manage information bank) region corresponding relationship.Sub-agent directly operates managed device, and when sub-agent starts, it is to primary proxy
Register various mib areas.Since sub-agent does not know the SNMP even presence of other sub-agents, primary proxy is responsible for filial generation
All possible conflict is arbitrated between reason, and as a part of mediation service, primary proxy provides index distribution and services and solve
The certainly overlap problem of mib area registration.
The overall structure of AgentX extension are as follows:
SNMP engine: sending and receiving SNMP message, executes SNMP access control policy；
AgentX primary proxy and sub-agent engine: AgentX-PDU(extension agency-protocol Data Unit is sended and received)；
Manage register machine: primary proxy is that sub-agent creates session, registration MIB subtree OID(object identifier), index point
Match.
Manage and dispatch machine: the SNMP packet parsing received is converted into AgentX-PDU by primary proxy, and according to registration
The judgement of MIB subtree is sent to suitable sub-agent, and the AgentX-PDU to be sent is converted into SNMP message and transfers to SNMP
Engine is sent to NMS(Network Management System).
Management application processor: creation and revocation, the registration of MIB subtree and note of the sub-agent to primary proxy application session
Pin, index are distributed and are de-assigned.
From the above-mentioned AgentX overall structure extended it can be seen that SNMP module is coupled with AgentX module height,
The data of SNMP resume module include AgentX data structure, and SNMP receives the message of NMS after treatment, is sent to AgentX
Data be still SNMP data, AgentX-PDU is converted by SNMP data by the manage and dispatch machine of AgentX, in AgentX
Inside modules handle SNMP data, and the extension as SNMP realizes that NMS passes through management of the SNMP to PON equipment.It is real in this NMS
The mode now communicated relies only on the management of SNMP module and AgentX realization to PON equipment, cannot be using other functions
Module is managed PON equipment with AgentX realization.
In conclusion the prior art is to be implemented in combination with external equipment or system (such as by SNMP module and AgentX
NMS) to the management of some functional modules in PON equipment, and SNMP module is relied only on, and others can not be relied on
Functional module, therefore, there is no how to utilize leading between each functional module in AgentX realization PON equipment in the prior art

In extract the sub-agent title, and to the sub-agent extracted send one include the operational order the second solicited message；
Step 204, the sub-agent extracted handle second solicited message and the response message of acquisition are sent to this
Primary proxy；
After step 205, the primary proxy receive the response message that the sub-agent extracted is sent, determines to send and be somebody's turn to do
First solicited message constructs the second message data including the response message and is simultaneously transmitted to this to the functional module of the IDB
IDB, while deleting the mapping relations of current IDB request and AgentX request；
The response message in the second message data is transmitted to by step 206, the IDB sends first solicited message
Functional module.
Wherein, which further includes that describe character string, action type and codomain slow for object identifier, object name
Area is rushed, which includes object identifier, session id and current AgentX request ID.
Moreover, in step 202, which searches the corresponding registration information of the first solicited message in its registration area,
According to the integration of the operating parameter of the sub-agent in the registration information found and the operational order, constructing one includes son
The first message data of the operating parameter of agency and the operational order.
In step 203, which searches the corresponding registration information of first message data, root in its registration area
It is investigated that the operating parameter of the sub-agent in the registration information found, the mapping relations of creation IDB request and AgentX request, i.e. root
A specific sub-agent can be uniquely determined according to IDB request.
In the present embodiment, which receives the response message that the primary proxy is sent in a manner of TCP/IP.But this field
Technical staff know that the mode that the present embodiment IDB receives the response message is not limited to the mode of above-mentioned selection, ability
The technical staff in domain also can be used other communication modes such as message queue mode or pipe method and realize that the IDB believes the response
