Network topological graph generation method and system

Abstract

The invention provides a network topological graph generation method and system. The method is applied to the network management operation environment of a simple network management protocol SNMP. The method comprises the steps that the management information base MIB of each network node in a target network is accessed, and whether border gateway protocol autonomous system BGPLocalAS information exists in the MIB is judged; the BGPLocalAS information and BGP peer table information are acquired under the condition that the BGPLocalAS information exists, and the neighbor relationship of the network nodes is stored in the BGP peer table information; whether the acquired BGPLocalAS information is correct is judged; network node icons corresponding to the BGPLocalAS are drawn according to the BGPLocalAS information under the condition that the acquired BGPLocalAS information is correct; and the connection relationship between the network node icons is established according to the BGP peer table information so as to complete a BGP network topological graph. Therefore, it can be seen from the BGP network topology based on the SNMP that the BGP visualized information can be provided according to the topological graph, visualization of BGP management can be realized, and effective management can be provided for network management and operation and maintenance and the operation and maintenance efficiency can be enhanced.

Description

technical field [0001] The invention relates to the management field of Border Gateway Protocol (BGP), in particular to a method and a system for generating a BGP network topology diagram. Background technique [0002] In the current network, Border Gateway Protocol (BGP) is frequently used. BGP is an exterior gateway routing protocol (or inter-domain routing protocol) designed for the TCP / IP (Transmission Control Protocol / Internet Interconnection Protocol) Internet, and is used between multiple autonomous domains AS (Autonomous System). BGP is a distance vector routing protocol, but it is neither based on a pure link state algorithm nor a pure distance vector algorithm. In the Internet, the main function of BGP is to exchange network reachability information with BGP of other ASs. Wherein, each autonomous domain AS may run different interior gateway routing protocols. Among them, the BGP update information includes the paired information of network number / autonomous doma...
