Example Embodiment

[0042] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] The Border Routing Protocol is a network inter-domain protocol, also known as the Border Gateway Protocol (BGP). As a distance vector type routing protocol, it is used to complete the routing selection between ASs. By monitoring the BGP routing change messages, the routing changes of the entire network can be obtained, and then the topology changes can be presented and managed. According to the network routing changes, the performance of the network can be evaluated, network configuration can be optimized, and network performance can be improved.

[0044] See figure 1 , The system of the present invention is composed of one or more monitoring nodes A distributed in each AS of the monitored network, figure 1 Only one monitoring node A is shown, and the moni...

Abstract

Route monitoring and analytic system among internet domain consists of one or more of monitoring node configured in AS of monitored network, which includes routing change information acquisition module, routing change message processing module, route topology management and whipping presentment module, and routing change information data base. Each monitor node is connected with network border route reflector neared router, to make node capable of being used as route reflector client-side to receive and monitor neared router issued route update information, through monitor route variation message in each AS to monitor domain route performance, and presenting each node route topology variation status and integrated all network topology variation status, to provide in time accuracy data for network operation and maintenance.

Description

technical field [0001] The invention relates to an Internet inter-domain route monitoring and analysis system and a working method thereof, belonging to the technical field of network interconnection communication. Background technique [0002] With the exponential growth of the Internet scale, its bandwidth capacity and underlying topology have undergone tremendous changes, the network structure has become increasingly complex, and network capabilities have been continuously enhanced. Today's IP network not only carries a large number of traditional data services such as HTTP and FTP, but also stream media services such as VOIP and IPTV continue to grow at a high speed. As we all know, the robustness and reliability of network operation are closely related to efficient and stable routing. In a large-scale operation network, especially when the network is under heavy traffic pressure, it is necessary to monitor the frequency of link status changes and unstable routing. real...
