IPv6中Neighbor Discovery协议及其测试

Neighbor Discovery Protocol and its Test in IPv6

IPv6协议是下一代互联网协议,NeighborDiscovery(邻居发现)协议是IPv6协议的一个重要组成部分,RFC2461是邻居发现协议的标准文本。为了检查各个生产厂家的实现是否与标准文本相一致,文章提出了一种协议一致性测试的方法,并开发了一个进行IPv6一致性测试的系统。该文提出了逻辑测试结构和虚拟测试器的概念,并在这个测试系统中应用了这两种测试结构和概念,还给出了一个邻居发现协议的测试实例。最后,给出了笔者对一种UNIX系统上实现的邻居发现协议进行一致性测试得到的结果,并对其与标准文本不一致的部分进行了分析说明。

Neighbor Discovery for IPv6is a main part of IPv6protocol.In order to assure the new protocol implementation to be consisstent with the standard and in turn to assure the interoperability between different IPv6implementations,an IPv6protocol conformance test system is developed.This paper proposes a logical testing architecture and the concept of virtual testers and presents the test method in the system.Also a test case example is given and the test results for a UNIX IPv6ND protocol implementation are discussed.
