Technical field

The present invention relates to the network management technology field, relate in particular to the method and system of processing equipment information in network management system.

Background technology

In Simple Network Management Protocol V1 (SNMPV1 agreement), (Trap is the standard term of snmp protocol to Trap protocol Data Unit (PDU), and domestic part Chinese material is translated as " trap message ", but inaccurate.) be defined as follows shown in:

EnterpriseID

agent-addr

generic-trap

specific-trap

time-stamp

variable-bindings

As follows to wherein relevant field feature description:

1, for a kind of equipment, the EnterpriseID of all SNMP Trap that it reports (proper noun of snmp protocol can be translated into: enterprise indicates) is identical, can map out the device type that reports TRAP by the EnterpriseID field;

2, variable-bindings (variable binding) field is by carrying out the variable binding in the equipment development process as required, the variable-binding field is not stipulated to fill in which content and fill in order in snmp protocol, therefore for different equipment, following situation can appear:

(1) different types of equipment content difference of in Trap, filling in;

(2) different types of equipment content of filling in Trap is identical, but the order of the field difference that these contents are filled in.

Like this, network management system is when using SNMPV1 consultative management equipment, though agreement is identical, but the form of Trap may be different, network management system will be managed the Trap that these equipment just must report these equipment respectively and be resolved, like this for the Integrated Network Management System of managing a large amount of heterogeneous devices, when change takes place the agreement of a kind of new equipment of management or certain equipment, will affect greatly network management system, because must change to existing network management system code, this not only can give the exploitation of network management system, management causes great inconvenience, and workload is big, the cost height.

The PDU type

?RequestID

N

m

SysUpTime

snmpTrapOid

variable-bindings

Wherein relevant field is described as follows:

(1) different with SNMP V1 agreement, deleted the EnterpriseID field among the Trap PDU of SNMP V2c and SNMP V3 agreement, so device type that does not have this Trap of field identification to report, but in SNMPV2c and SNMP V3 agreement, increased SNMP TrapOid field, for the identical Trap of SNMP TrapOid, the field contents that its variable-bindings fills in is identical with order.

(2) for the different Trap of SNMP TrapOid, the content of its variable-bindings may be different with order.

When network management system is used SNMP V2 or SNMP V3 management equipment, exist the problem identical with SNMP V1.

Embodiment

The present invention isolates the influence of inhomogeneous SNMP Trap to network management system by low coupled modes, makes network management system under the situation that does not change original design, and the SNMP Trap that different equipment is reported handles.Below mainly adopting SNMP V1 agreement with network management system is that example describes.

In SNMP V1 agreement, the EnterpriseID field is that implication is clear and definite and explicitly call for the field that must fill in agreement, if a kind of equipment uses SNMP V1 agreement and network management communication, this field must be filled in SNMP Trap, and the SNMP Trap that reports for same kind equipment, this field is identical.Therefore can utilize this field as keyword, the SNMP Trap that different equipment is reported carries out different processing.

Inhomogeneous SNMP Trap for distinct device reports resolves SNMP Trap by plug-in dynamic base, the unified structural information that the structure after the parsing is determined when designing by network management system, and this structure all is identical to all dynamic base.The processing function of this dynamic base of processing SNMP Trap that pairing equipment reports is provided in the dynamic base, and this function is input as the original SNMP Trap that equipment reports, and is output as unified structural information.

Each dynamic base provides an export function, returns the corresponding relation of EnterpriseID and the function of the SNMP Trap that handles this EnterpriseID corresponding equipment in this export function.If the processing function of multiple SNMP Trap is provided in dynamic base, then need to return all corresponding relations in this dynamic base export function, this export function calls for main program.

Consult shown in Figure 1ly, network management system treatment S NMP Trap idiographic flow is as follows:

Step 10: network management system loads all SNMP Trap and resolves dynamic base when starting.

Step 20: call the corresponding relation that the dynamic base export function obtains equipment EnterpriseID and this kind equipment SNMP Trap processing function, and this corresponding relation is preserved in internal memory.

Step 30: behind the SNMP Trap that the network management system equipment of receiving reports, from SNMP Trap, obtain EnterpriseID.

Step 40: the processing function that from the corresponding relation that step 20 is set up, finds this kind SNMP Trap according to the EnterpriseID that obtains in the step 30.

Step 50:, resolve to the information of unified structure through this processing function with the processing function that finds in the SNMP Trap input step 40.

Step 60: network management system is handled the unified structural information that parses in the step 50.

Adopt above processing mode,, then only need to revise the dynamic base of this kind SNMP Trap correspondence, do not need to revise the network management system main program if the SNMP Trap form of network management system management equipment changes; If increase a kind of new equipment of management, only need provide the dynamic base that this kind equipment SNMP Trap is resolved, can not impact the network management system handling process yet, thereby effectively shield the influence of device protocol variation network management system.

In SNMP V2c or SNMP V3 agreement, removed the EnterpriseID among the SNMP Trap, but in SNMP V2c and SNMP V3 agreement, one class SNMP Trap can use SNMP TrapOid to identify, and SNMP TrapOid is the field that equipment must be filled in reporting SNMP Trap process process.Therefore for said method, need be SNMP TrapOid with the content modification of handling EnterpriseID only, this method be promptly applicable, and its processing procedure is identical.

According to said method and in conjunction with prior art, network management system that can accomplished said method.This system constitutes the well-known components except comprising processor and memory etc., also comprises:

Be used to provide the analytical function of the SNMP Trap that analyzing device reports, and first device that has corresponding relation between the identification marking of the SNMP Trap that resolved of analytical function and this analytical function of sign;

Be used for from first device obtain described corresponding relation and be stored in system second the device;

Be used for the SNMP Trap that slave unit reports and extract identification marking, utilize this sign from second device, to find the analytical function of resolving this SNMP Trap, and from first device, call the 3rd device that this function is resolved this SNMP Trap and the unified structural information of output; And

The 4th device that the unified structural information of the 3rd device output is handled.

Adopt the present invention, Integrated Network Management System can be effectively when the different equipment of management comes the design isolated of SNMP Trap protocol processes and network management system, like this when a kind of equipment of new management or the device protocol managed change, the design of network management system is not impacted.

Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
