一种基于数据层的BGP网络前缀分类研究

摘要

Boarder Gateway Protocol (BGP) has been a critical part of Internet routing system and drawn attention from many researchers. With the exhausting of IPv4 addresses and growing number of routing table size, researchers ifnd it important to ensure BGP routing system's security. To get better understanding for how BGP network operates, the classification for reasons which generates BGP preifxes becomes a vital work. In this paper a new method was proposed by utilizing data from data panel. Analyzing with data extracted from Traceroute program, preifx span is created to help get better classiifcation result for BGP preifxes.%边界网关协议(Boarder Gateway Protocol, BGP)是互联网路由的核心系统,一直受到研究者们的高度关注.随着IP地址的枯竭、核心路由器的路由表持续增加,如何确保BGP路由系统的安全成为了研究人员关注的问题.对BGP消息的产生原因进行分类,是理解BGP路由系统的工作原理,并探究现有骨干网网络环境,保障BGP安全的重要工作.文章提出的基于路由数据层的BGP网络前缀分类方法,对数据层Traceroute搜集到的拓扑数据进行分析,划分出网络前缀活动期,对网络前缀的产生原因进一步分类.
