Embodiment 1

[0022] Example 1. A network topology construction method based on SNMP protocol, the construction method includes topology information collection, information extraction, information filtering and topology construction.

[0023] The aforementioned topology information collection is to use a multi-thread mode to simultaneously collect the SNMP information stored in real time in the MIB library of the SNMP protocol of the router in the topology network to be constructed, and the SNMP information includes device port IP address information, port information and system information. SNMP information is stored in a MySQL database.

[0024] The aforementioned topology information collection adopts the passive collection of SNMP information. In this way, according to the characteristics of many nodes in the network, far-distributed nodes and high information transmission delay, the multi-thread mode can be used to collect SNMP information on each router at the same time, so as to impr...

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...
