摘要： 在TTCN-3测试系统的实现过程中，需要划分系统中与被测相关和无关的部分。分析与被测相关部分的编解码器和TRI中与协议相关的功能函数，并讨论它们的实现方法。以DHCPv6协议为例给出相关函数的实现算法，通过测试系统各部分的协作图阐述测试系统的工作过程。

Abstract: During the processing of implementation of TTCN-3 test system, there are requirements to divide the test system into protocol related part and System Under Test(SUT) unrelated part. This paper analyzes Coder/Decoder(CD) and Test Runtime Interface(TRI) functions of protocol related part. The implementation approach is discussed. As an example, DHCPv6 related algorithms are given. And the working process of the test system is interpreted by the collaboration diagram of TTCN-3 test system component.

Key words: test, protocol, implementation
