Research Of The Key Technologies Applied In Conformance Testing Of Mobile IPv6 Protocol Based On TTCN-3

With the rapid development of the computer, the Internet, and the mobile communications technology, cell phones, laptops, PDAs and other mobile communications equipment has been widely used. Internet is gradually going out of its original military, scientific research and educational fields, and then penetrating into people's daily life. Therefore, people want to access the Internet even in movement. The Working Group of Mobile IP, which is under the IETF (Internet Engineering Task Force), developed the first standard Mobile IP (Mobile IPv4) in the 1990s. With the gradual transition from IPv4 to IPv6, the IETF has started drawing up a new mobile IPv6 protocol.The Mobile IPv6 (or MIPv6) protocol has become an important component of the IPv6 protocol cluster. With the booming development of MIPv6 technology, the Conformance Testing of MIPv6 implement must also be followed. Conformance Testing, a kind of Protocol Testing that based on the protocol described in text form, is used to test whether the protocol implement is according with the standard protocol. TTCN-3(Testing and Test Control Notation 3^rd version) is a new standard established by ETSI (European Telecommunications Standards Institute), which is designed for protocol and software testing. It has powerful functions and a wide range of applications. This issue involved the research of the conformance testing of MIPv6 based on TTCN-3, which can be a useful attempt.In this thesis, several key technologies that applied in conformance testing of MIPv6 based on the TTCN-3 are introduced. By analyzing the characteristics of the project, one testing system's structure is proposed; the problem of communication technology is solved by improving and fixing the Jpcap functions; the testing system's adapter is designed and implemented; and one Parallel Testing technology is proposed. MIPv6 conformance testing is conducted by combing these and ATS (Abstract Test Suite) in corresponding test environment, and the expected test results are presented in the thesis. The research on the topic can play a positive role in promoting the testing and popularization of MIPv6 products.
