Embodiment Construction

[0082] In order to make the object, technical solution and advantages of the present invention clearer, the following describes in detail a BGP network anomaly monitoring system and method of the present invention in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0083] Please refer to figure 1 , which is a flow chart of a BGP network abnormality monitoring method of the present invention. A method for abnormality monitoring of a border gateway protocol network of the present invention comprises the following steps:

[0084] Step S100, use a collector to simulate a router, and establish a BGP adjacency relationship with a specific BGP node (autonomous system) in the BGP network, so that the collector can pass through the specific BGP A node is connected to all BGP nodes in the BGP network, that is, the union o...

Abstract

The invention relates to computer network technology and discloses a system and a method for monitoring the abnormity of a border gateway protocol (BGP) network. The method comprises the following steps: collecting BGP advertisement update messages in the BGP network, constructing a character string v corresponding to each collected BGP update message, adding the character strings v to a character string assembly V, searching a character substring vsub with the highest appearance frequency as the position where the BGP network abnormity occurs, and speculating the reason inducing the BGP network abnormity according to the content of the character substring vsub following a routing behavior analysis method. The invention can more effectively monitor BGP network abnormity and analyzing abnormity reason, with remarkably improved accuracy and simplicity.

Description

technical field [0001] The invention relates to computer network technology, in particular to an abnormality monitoring system and method of a border gateway protocol network. Background technique [0002] In the Internet (internet) architecture, a router is a network device used to connect multiple networks or network segments. It can "translate" data information between different networks or network segments so that they can communicate with each other. Read" to understand each other's data, thus forming a larger network. People divide numerous routers into autonomous systems (ASs), and each autonomous system is a group of routers and networks under the control of a management organization. The interior gateway protocol (IGP) is run inside the autonomous system, and the exterior gateway protocol (EGP) is run between autonomous systems. Currently, the Border Gateway Protocol (BGP) is the de facto standard protocol for routing between autonomous systems. Therefore, the ope...
