Embodiment 1

[0022] Embodiment one, see figure 1 As shown, a heterogeneous redundant Snmp protocol multi-instance implementation system, a heterogeneous redundant Snmp protocol multi-instance implementation system, includes an Snmp agent unit, an Snmp protocol executive module, and a dynamic scheduling unit, wherein the Snmp agent unit, Responsible for receiving the Snmp protocol request from the network management terminal, copying and distributing the request message to the Snmp protocol execution body module; the Snmp protocol execution body module processes according to the type of Snmp protocol request, sends the processing result to the dynamic scheduling unit, and executes the Snmp protocol The body module includes N heterogeneous Snmp protocol executive units running in parallel; the dynamic scheduling unit maintains the heterogeneous Snmp protocol executive units, and arbitrates the calculation results of all the Snmp protocol executive units according to the majority optimization ...

Embodiment 2

[0024] Embodiment 2 is basically the same as Embodiment 1, except that: the Snmp protocol request types of the network management terminal include Snmpset messages and Snmpget messages.

[0025] The specific content of the majority selection mechanism is as follows: among multiple heterogeneous Snmp protocol executive units running in parallel, if the calculation results of more than two Snmp protocol executive units are the same, the calculation result with the most identical times will be used as the arbitration result. If the operation results of each Snmp protocol executive unit are different, the operation result of the Snmp protocol execution unit with the highest priority is used as the arbitration result.

Embodiment 3

[0026] Embodiment three, see figure 2 As shown, a heterogeneous redundant Snmp protocol multi-instance implementation method, based on the heterogeneous redundant Snmp protocol multi-instance implementation system described in Embodiment 1, specifically includes the following steps:

[0027] Step 1, the Snmp agent unit receives the Snmp request command of the network management terminal, establishes an internal Snmp session connection with a plurality of heterogeneous Snmp protocol executive units running in parallel, copies the Snmp request command and distributes it to each Snmp protocol execution through the internal Snmp session connection The body unit, the Snmp request command includes the Snmpset command and the Snmpget command;

[0028] Step 2, after receiving the Snmp request command, each SNMP protocol executive unit performs operations respectively, and notifies the operation result to the dynamic dispatching unit;

[0029] Step 3. The dynamic scheduling unit perf...

Abstract

The invention relates to a heterogeneous redundancy SNMP multi-case implementation system and method. The system comprises an SNMP proxy unit, an SNMP executor module, and a dynamic scheduling unit, wherein the SNMP executor module comprises N heterogeneous SNMP executor units which are run in parallel; the heterogeneous SNMP executor units are simultaneously run in parallel; and the dynamic scheduling unit judges operation results of the SNMP case execution units through a majority and preferential selection mechanism, and outputs a judged configuration result to a routing control plane and a data plane or sends a judged search result to a network management terminal. The system and method provided by the invention has the advantages that the problem in the prior art that the single SNMP invalidity in a router causes abnormality of a router management plane is solved, the installation and deployment are simple, the deployment is flexible, and the fault tolerance is high.

Description

technical field [0001] The invention belongs to the technical field of Snmp protocol realization in network communication technology, and in particular relates to a heterogeneous redundant Snmp protocol multi-instance realization system and a realization method thereof. Background technique [0002] As a core component of network infrastructure, routers are facing increasingly severe security situations. The SNMP protocol, as an important part of the router management plane, realizes the configuration management, query and alarm notification functions of the router, and its security situation is not optimistic. The SNMP protocol mainly faces attacks from loopholes or backdoors. Traditional routers respond to attacks based on known vulnerabilities or backdoors by patching the vulnerabilities of the Snmp protocol and adding additional security mechanisms, but they are helpless against unknown vulnerabilities or backdoors. Solve the vulnerability of SNMP protocol and Mib info...
