Problems solved by technology

However, it does not give users an intuitive interface display, which is not easy to manage
The LSAR component of the above-mentioned monitoring system collects all LSAs. According to the OSPF protocol, there is a large amount of redundancy in all the above-mentioned LSAs, which is a waste of storage space; and each topology change information generated by LSAG is only contains a time stamp, therefore, it is difficult to obtain topology information at a certain historical moment only from these topology change information: for example, a router with "RTR UP" appears at time t0, it is difficult to know whether it still exists at time t1, solve The only way is to traverse all topology change information from time t0 to time t1

Embodiment Construction

[0024] The invention provides a route monitoring device.

[0025] Inter-domain route monitoring is the monitoring of BGP routes. Currently, the most commonly used external gateway protocol is BGP-4 (Border Gateway Protocol Version 4, Border Gateway Protocol Version 4). BGP-4 is a complex distributed dynamic routing protocol used between autonomous systems. The main function of BGP-4 is to exchange network reachability information between systems implementing the BGP-4 protocol. These network reachability information include a list of autonomous systems traversed by a route, which is used to establish a graph representing the connection state, so as to solve the routing loop problem and make routing selection based on AS (Access Server, access server) strategy is possible.

[0026] After the two BGP-4 Speakers establish a TCP connection, they negotiate parameters and start exchanging routing information after reaching an agreement. In this initial situation, the two BGP-4 spe...

Abstract

The present invention provides a rout monitoring apparatus which mostly includes: data acquisition module for collecting network rout information, and transmitting collected network rout information to data storage module; data storage module for generating topological information, network affair according to rout information from data acquisition module; storing the rout information, topological information, network affair; data-processing module for executing analyze and process storage data of data storage module, monitoring routing action of network, obtaining routing action data information of network, judging node and circuit of network fault; interface display module for displaying obtained network fault node and circuit information of data-processing module through interface. Using the invention can judge defective node and circuit accurately, and execute effectually monitoring to fault of wireless communication network.

Description

technical field [0001] The invention relates to the communication field, in particular to a routing monitoring device for a communication network. Background technique [0002] The routing monitoring system in the computer network is divided into the monitoring of the routing within the autonomous domain and the monitoring of the routing between the autonomous domains. The monitoring of routes in the autonomous domain mainly refers to the monitoring of OSPF (Open Shortest Path First, Open Shortest Path First) routes. The monitoring of inter-autonomous domain routes mainly refers to the monitoring of BGP (Border Gateway Protocol, Border Gateway Protocol) routes. [0003] For link-state based routing protocols, each router maintains a global network topology database within its routing domain. Any network fault will be reflected by the change of the topology database, and by analyzing the relationship between the network fault and the change of the topology database, the net...
