Research And Implementation Of Dynamic And Stable Routing Exception Analysis System

The network can be divided into IP level network,routing level network,and AS level network.Routing level network plays a connecting role.The performance of the routing network is related to data transmission efficiency and network security.Routing network is the core of the whole Internet.Understanding the routing network is a crucial step to understand,use and manage the Internet and improve cyberspace security.It can effectively improve the communication speed,reduce the load of the network system in the communication,save the resources of the network system,improve the smoothing rate of the network system,and make the network system play a more significant economic benefit.But if a routing network suddenly fails,it will directly lead to the local network's severe paralysis.If the backbone routing network,its affected degree will be greater,caused by the economic loss is difficult to estimate.In the routing network,the routing has the characteristics of large quantity,dynamic and changeable.The rapid growth of networks leads to the increasing complexity of network structure and frequent routing abnormal events.Therefore,this system is needed to quickly recognize the network structure and how to analyze and discover the routing anomaly events.This system will combine the two characteristics of the network: dynamic and stability for analysis.Dynamics is proposed to understand end-to-end delay,packet loss rate,and path changes,which can be obtained through IP-level analysis.The instability of the network will be directly displayed on the BGP,which is obtained through the analysis on the AS level.So when routing configuration errors directly affect the dynamics of IP level and AS level on the stability of combining with dynamic and stability characteristics,therefore,this paper designed a dynamic and stability-oriented routing anomaly analysis system,and to rapid cognitive network,hence the need for routing node topology construction.The main research contents of this paper are as follows.(1)Dynamic characteristics analysis The parameters such as accessibility,length transformation,and path change are analyzed.An optimization method of routing IP anomaly location based on the similarity between backbone network and delay is proposed.Then the exception is analyzed at the IP level.(2)Routing stable analysis Eleven common and important abnormal features were summarized,including the active degree of the prefix,the life cycle of the prefix,the frequency of repeated declaration,and the frequency of redundant revocation.The BGP anomaly system was constructed,and the anomaly detection of BGP UPDATE messages was carried out.Routing exceptions in this module are analyzed at the AS level.(3)Topology construction Since the routing level is mainly analyzed,the main task is to solve the problem of anonymous nodes and transform IP-level networks into the routing-level network.Therefore,this paper proposes an anonymous node fusion method based on the clustering idea,reducing the error of the non-simultaneous acquisition delay curve.Physical and logical typologies are presented.
