1.2 - Application of a TTCN Based Protocal Integrated Testing System on the Transmission Control Protocal Authors: Xia Yin and Jianping Wu Univ/Comp: Tsinghua Univ., P.R.C. Presenter: Xia Yin - yxia@csnet1.cs.tsinghua.edu.cn ******** Abstract: This paper presents the conformance testing of Transmission Control Protocol using an integrated test system PITS. With reasonable modulate design in system architecture and TTCN based test execution, PITS could test both the OSI and Internet protocols. Conformance testing of TCP is one of the successful applications in PITS. In this paper, we discuss test method for testing TCP and the design of TTCN based TCP test suite in detail.
