Network topology construction method based on SNMP

Abstract

The invention discloses a network topology construction method based on SNMP. The network topology construction method comprises topological information acquisition, information extraction, information filtration and topology construction, and is high in construction efficiency, low in network load, and reasonable in topological layout.

Description

technical field [0001] The invention relates to a method for constructing a computer network topology, in particular to a method for constructing a network topology based on the SNMP protocol. Background technique [0002] In recent years, with the expansion of the network scale, it is very cumbersome and difficult to update the topology manually. The automatic construction method of network topology has been developed rapidly. There are many researches on topology construction methods at home and abroad, but many researches are based on local range. The current network topology construction method can be divided into single management domain and multi-management domain according to the construction scope, can be divided into network layer topology construction and link layer topology construction according to the construction protocol level, and can be divided into passive detection and active detection according to the construction method. At present, the automatic constr...

Problems solved by technology

The traditional method of manually constructing network topology mainly has the following disadvantages: topology construction efficiency is low, topology update is not timely, topology construction is prone to manual errors, and complex topology planning and construction is difficult; based on ICMP protocol, RIP protocol, DNS and The topology construction method based on the OSPF protocol makes the network load higher, which may cause local network congestion, and is not suitable for networks with huge network data traffic
