Problems solved by technology

Therefore, for these two types of operations, the SNMP agent usually needs to traverse the MIB tree frequently. The traversal method of the MIB tree will greatly affect the speed at which the SNMP agent responds to the NMS request. When the number of leaf nodes in a table is particularly large, this Will cause relatively large algorithm overhead

Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] see figure 1 As shown, the first embodiment of the present invention provides a simple network management protocol proxy query method, the method includes the following steps:

[0031] S110. The Simple Network Management Protocol SNMP agent receives a GetNext or GetBulk request message from the network management system NMS for the managed object in the MIB.

[0032] S120. When there is no instance in the current MIB table searched by the SNMP agent, then skip the current MIB table, start searching from the first node of the next MIB table of the current MIB table, and return the search result, wherein, the current MIB table A table includes at least two leaf nodes.

[0033] Some MIB nodes include some MIB tables. A MIB table corresponds to a class of objects, and the table can contain each instance of the object, and each co...

Abstract

The invention discloses a query method for a simple network management protocol agent, a MIB tree traversal method and a system, and relates to the technical field of communication. This inquiry method comprises the following steps: simple network management protocol SNMP agent receives network management system NMS to the request message of GetNext or GetBulk of the managed object in the management information base MIB; , then skip the current MIB table, search from the first node in the next MIB table of the current MIB table, and return the search result, wherein the current MIB table includes at least two leaf nodes. The invention can reduce the processing algorithm overhead of the SNMP agent for the GetNext and GetBulk requests, bring optimization effect, and improve the response speed of the network equipment for the GetNext and GetBulk requests.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a simple network management protocol proxy query method, MIB tree traversal method and system. Background technique [0002] Simple Network Management Protocol (SNMP) is an application layer protocol based on TCP / IP, mainly used for the management of network devices. The SNMP protocol provides a unified cross-platform device management method. The Network Management System (NMS) can collect device information, modify device parameter values, and monitor device status through the SNMP protocol. The software module used to maintain various information data and respond to NMS operation requests on the managed device is called SNMP agent (SNMP Agent). Each SNMP agent has its own management information base (Management Information Base, MIB). The MIB is a hierarchical tree structure, and the nodes of the tree represent managed objects. The MIB provides the data structure of a c...
