协议一致性测试是验证计算机网络协议实现与其国际标准是否一致的关键技术。３Ｘ协议是公用分组交换数据网中一组应用十分广泛的协议标准，对其进行一致性测试是十分重要的。本文首先对３Ｘ协议及其应用进行介绍，然后从测试角度对被测系统进行分析，最后给出一种基于数表组合表述法ＴＴＣＮ（ＴｈｅＴｒｅｅａｎｄＴａｂｕｌａｒＣｏｍｂｉｎｅｄＮｏｔａｔｉｏｎ）的３Ｘ协议一致性测试组织
Protocol conformance testing is to verify the computer network protocol to achieve its international standards are consistent with the key technologies. 3X protocol is a widely used set of protocol standards in public packet-switched data networks. It is very important that the 3X protocol performs conformance testing. This paper first introduces the 3X protocol and its application, and then analyzes the system under test from the perspective of testing. Finally, we present a 3X protocol conformance testing organization based on TTCN (TheTreeandTabularCombinedNotation)
