Design And Implementation Of The Conformance Test System For IPv6Translation Transition Technology

Following the growing number of Internet users, the Internet users appeal for the multi-services support and better safety and mobility performance. The study of next-generation network based on IPv6is imminent. But because of the complicacy and broad coverage of the nowaday IPv4network environment, the transition from IPv4to IPv6will be a long process. It is extremely important for the transition technology working with a stable transition device. Protocol conformance test can ensure the interconnection of transition devices. Because the technique of IPv6translation transition technology conformance testing belongs to a new research field, so has not been seen in other studies in the literature.This thesis is based on IPv6translation transition technology study, deep analysis of four different translation transition technologies, combined with conformance testing standards, designs and manages conformance test set with modular and tree models, realizes four kinds of IPv6translation transition technology conformance test.The paper first analyses the research background, introduces the existing IPv6transition technology and IPv6protocol conformance test. Then we make a detailed introduction of the three IPv6transition technologies, including dual stack technology, tunnel technology and IPv6translation transition technology.Combined with protocol conformance testing theory, refers to IPv6protocol conformance test model, this thesis presents a unique form of modular and tree models to design IPv6translation transition technology conformance test suit. Based on these models, this thesis introduces the process of the design.Based on the construction of conformance test suits, this thesis implements IPv6translation transition technology conformance test system with three key modules, the interpreter subsystem, actuator subsystem and interface subsystem. Finally, we run the four translation transition test cases to testify the availability and validity of this system.This thesis offers a powerful tool for IPv6translation transition technology conformance test. It will ensure the interconnection between transition equipments.
