Description

A kind of method that realizes that multi-standard management infor mation library of agent part merges

Technical field

The present invention relates to network management technology, relate in particular to the network management of SNMP.

Background technology

Along with the high speed development of network technology, (next generation network: Next Generaion Network) network has been walked out the laboratory to NGN, develops into the epoch of scale commercialization.In the NGN network, exist a large amount of terminal equipments, for example: HGW (home gateway: Home Gateway), IAD (integrated access device: Integrated Access Device) etc.Along with the scale operation of network, to effective problem of having managed of these equipment into necessary solution.Now SNMP (Simple Network Management Protocol: agreement Simple Network Management Protocol) is adopted in the management of these terminal equipments usually.As shown in Figure 1, the realization of snmp protocol is finished jointly by snmp management device 10 and SNMP proxy server 11.Snmp management device 10 and SNMP proxy server 11 shared MIB (management information bank: 12 information of describing SNMP proxy server 11 place equipment ManagementInformation Base), snmp management device 10 is communicated by letter with SNMP proxy server 11 by the GET/GET-NEXT/SET/GET-RESPONSE/ operation, and SNMP proxy server 11 uses TRAP (self-trapping) initiatively to communicate by letter with snmp management device 10.Snmp management device 10 is servers, and 11 of SNMP proxy servers are realized on by the terminal equipment of snmp management device 10 management.

Terminal equipment has characteristics, and that is exactly that environment for use is indefinite, such as a same IAD equipment, may be operated under the different network management environment, promptly works under different SNMP network managers, and each snmp management device has different MIB.Can problem have just occurred like this, when terminal equipment changes environment, require the webmaster environment also to change, support more MIB? the snmp management device is that operator safeguards in the actual environment, can the frequent upgrading because the equipment of being managed changes.Therefore in order to strengthen the adaptive capacity of terminal equipment, need act on behalf of side at SNMP and realize that many standard mibs merge network management environment.

Number of patent application is that the Chinese patent of CN200410009251.2 discloses a kind of " method that the MIB version is coordinated between snmp management station and the agency ", this patent has only proposed the way of sign MIB version, the MIB with various criterion merges, and can not reach a requirement with equipment support multiple network management environment of SNMP agency.

Number of patent application is the United States Patent (USP) " SYSTEM AND METHODFOR CONTROLLING TRAP GENERATION OF SIMPLE NETWORKMANAGEMENT PROTOCOL (SNMP) BY DEFINING AND USING A TRAPFLAG FIELD AND A TRAP PEER FIELD IN THE MANAGEDINFORMATION BASE (MIB) " of US6854011 B2, discloses a kind of method that produces TRAP by flag bit control.This patent has only proposed to produce the method for different TRAP, equally not with the MIB fusion of various criterion, can not reach a requirement with equipment support multiple network management environment of SNMP agency.

Summary of the invention

Technical problem to be solved by this invention provides a kind of method that realizes that multi-standard management infor mation library of agent part merges, and makes snmp management device and SNMP proxy server not need upgrading, and the SNMP agent equipment just can be operated in the different network management environment.

The invention provides a kind of method that realizes that multi-standard management infor mation library of agent part merges, may further comprise the steps:

(a) set up a plurality of standard mibs and merge the fusion management information bank that comprises all object identifier nodes of these standard mibs that obtains;

(b) each object identifier node with described fusion management information bank joins in the management information base tree of snmp agent device, and handles function G ET/SET for each described object identifier node provides;

(c) the management information library standard of supporting according to the network management environment of described proxy server needs work, configuration are used to identify the configuration item of the management information library standard of the current support of this proxy server;

(d) described proxy server is when the simple network management protocol management device reports Trap message, identify the management information library standard of current support according to the Configuration Values of described configuration item, the object identifier in this standard is tied to reports described manager in the Trap message.

Further, said method also can have following characteristics: in the described step (a), set up to merge management information bank and be by based on any one standard mib tree, object identifier node inequality adds to and realizes in this basic management information base tree during other standard mibs are set.

Further, said method also can have following characteristics: further comprising the steps of: described manager manages it by the operation of object identifier node that the own management information library standard of being supported in the described proxy server is comprised.

Further, said method also can have following characteristics: in the time of on described proxy server need being connected to the simple network management protocol management device of supporting another management information library standard, only need to revise the Configuration Values of the Configuration Values of the described configuration item of described proxy server for described another management information library standard of sign.

As from the foregoing, the inventive method makes terminal equipment strengthen the adaptability to network management environment greatly.When network management environment changes, only need the configuration item modification of the current mib standard of sign is got final product, do not need the updating terminal device version, do not need snmp management station upgraded version yet.

Description of drawings

Fig. 1 is existing snmp management device and SNMP proxy server course of work schematic diagram.

Fig. 2 is the structured flowchart of snmp management system in the embodiment of the invention.

Fig. 3 is the flow chart that the embodiment of the invention realizes many standard mibs fusion method.

Embodiment

Below in conjunction with the drawings and specific embodiments the present invention is further described.

Present embodiment is with the example that is fused to of two standard mibs, and the system that the system that Fig. 2 connects and composes same SNMP proxy server and snmp management device MANAGER_A and this SNMP proxy server and snmp management device MANAGER_B connect and compose is drawn on the figure and represents.The structure of snmp management system comprises snmp management device, SNMP proxy server and MIB module.Wherein:

The snmp management device needn't be done any variation.The MIB module should store the fusion mib file that comprises each standard mib, and this document comprises OID nodes all in each standard mib.And the SNMP proxy server merges in order to realize many standard mibs, needs to preserve each OID node that merges among the MIB_AB, and is that the GET/SET that each OID node adds handles function.Also need by a configuration interface, finish configuration the configuration item MIB_CFG_STANDARD of the mib standard that is used for identifying the current support of SNMP proxy server.In addition, SNMP should bind OID in this standard according to the mib standard of current configuration when sending TRAP message to the snmp management device.

Present embodiment is realized the method that two standard mibs merge, and as shown in Figure 3, may further comprise the steps:

Step 110 is set up standard mib _ A and standard mib _ B and is merged the MIB_AB file that obtains, and this MIB_AB file comprises all OID nodes of standard mib _ A and standard mib _ B;

Because MIB is a tree, (object identifier: Object Identifier) node adds in the MIB_B tree only to need the OID that do not have in the MIB_B tree in will the MIB_A tree during fusion, added in the MIB_B tree of back and comprised OID nodes all among MIB_A and the MIB_B, then MIB_B is the MIB_AB after the fusion.Be peer-to-peer between MIB_A and the MIB_B, the OID node that does not have in the MIB_A tree in the MIB_B tree added in the MIB_A tree, also the MIB_AB that can obtain merging.

Step 120 joins each OID node that merges MIB_AB in the MIB tree of SNMP proxy server, and handles function G ET/SET for each OID node provides;

Step 130, the mib standard of supporting according to the network management environment of SNMP proxy server needs work is used to identify the configuration item MIB_CFG_STANDARD of the mib standard that current SNMP proxy server supports by the configuration interface configuration;

When the SNMP proxy server is connected to snmp management device MANAGER_A and goes up, the Configuration Values of configuration item MIB_CFG_STANDARD is made as A_MIB, that represent that this snmp management device MANAGER_A uses is the MIB of MIB_A standard; When the SNMP proxy server is connected to snmp management device MANAGER_B and goes up, the Configuration Values of configuration item MIB_CFG_STANDARD is made as B_MIB, that represent that this snmp management device MANAGER_B uses is the MIB of MIB_B standard.

Step 140, snmp management device MANAGER_A or MANAGER_B manage it by the operations such as GET/SET of OID node that MIB_A or MIB_B in the SNMP proxy server are comprised;

In the present embodiment, the MIB_AB of fusion is transparent to the snmp management device, does not need the snmp management device is done any change.

When step 150, SNMP proxy server report TRAP to the snmp management device, identify the mib standard of current configuration, the OID in this standard is tied to reports the snmp management device in the TRAP message according to the Configuration Values of current MIB_CFG_STANDARD;

Step 160, in the time of on the SNMP proxy server need being connected to the snmp management device of supporting another mib standard, only need the configuration item MIB_CFG_STANDARD that revises the SNMP proxy server to get final product, certainly, the mib standard that this snmp management device uses should be the mib standard after merging.

For example, the SNMP proxy server was connected with snmp management device MANAGER_A originally, change into when being connected with snmp management device MANAGER_B, only the Configuration Values that need revise the configuration item MIB_CFG_STANDARD of SNMP proxy server by configuration interface is B_MIB, and the SNMP proxy server is operated in the network management environment of snmp management device MANAGER_B.

In another embodiment of the present invention, in the SNMP proxy server, set up the mib file that merges a plurality of standard mibs, because between each standard mib be the tree-like relation of equity, always can constantly synthetic one of the MIB of a plurality of standards be merged MIB, it is convenient feasible therefore merging a plurality of standard mibs.Correspondingly, in the present embodiment, the MIB_CFG_STANDARD configuration item also adopts a plurality of Configuration Values, identifies the MIB of a plurality of various criterions, and this SNMP proxy server can be worked in the network management environment of the snmp management device of the different mib standards of a plurality of employings.

In sum, adopt system and method for the present invention, when the SNMP proxy server was operated in the different network management environment, the Configuration Values that the SNMP proxy server only need change configuration item got final product, do not need SNMP proxy server or SNMP network manager the upgrading or restart.
