A method and system for generating a network topology map

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 present invention relates to the field of Border Gateway Protocol (BGP) management, and in particular to a method and system for generating a BGP network topology map. Background technique [0002] In the current network, the Border Gateway Protocol (BGP) is frequently used. BGP is an external 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 domain ASs (Autonomous Systems). 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 in other autonomous domains. Among them, each autonomous domain AS can run different internal gateway routing protocols. Among them, the BGP update information includes the paired information of the net...

[0003] In traditional network management, for example, the network management supported by Simple Network Management Protocol (SNMP) (Simple Network Management Protocol, which is composed of a set of network management standards), wherein, SNMP uses the information table ifTable and IP address table ipAddrTable in RFC-1213 And the manufacturer's private SNMP information for management, focusing on the physical level, but lacking the means for BGP protocol management
