BGP前缀劫持下的通信研究与实现

摘要

针对当前互联网上发生的BGP前缀劫持事件,分析BGP前缀劫持检测系统的通信方式,为解决BGP前缀劫持发生后产生的通信困局提供方法支撑,从而为分布式的BGP前缀劫持检测系统消息通告设计与实现提供参考.文章以当前BGP前缀劫持检测系统为背景,基于前缀劫持中受害者AS、感染者AS和未受感染者AS的通信关系,提出几种旨在打破通信困局的启发式消息宣告机制并对其各种机制的特点进行了分析.%Analyzing the communications in BGP Prefix Hijacking detecting systems and designing a cooperative message transfer method will help to cope with the communication dilemma in Prefix-Hijackings. Based on the relationships among victim Ases, infected Ases and non-infected Ases, this paper proposed several message distributing mechanisms, including broadcasting, unicasting and predicted unicasing to solve the communication problems and their performances are evaluated at the end of the paper.
