Research And Implementation Of IPv6 Conformance Testing

Being the most important one of internet protocols in the next generation,IPv6 is rapidly spreading in use. At the same time, it is very important that the IPv6 products of producers'are whether or not conformable to RFCs to be safe and reliable in communications. Therefore,as the method to justify that the IPv6 products are conformable to RFCs or not,IPv6 conformance testing is playing an important role in the progress of IPv6.This thesis makes a deep research in conformance testing theory around IPv6 conformance testing,and surveys the recent development in the state-of-the art of conformance testing. Then the test generation methods in the area of communication are investigated and the merits and shortcomings of the methods are analyzed. All above this,to solve the problem that the state map of IPv6 protocol generated with FSM method is too scattered,a new test generation method called B-U method is proposed. By rebuilding the state map to cover more state in one map,this method make the problem well solved and that is more simpler and understandable. This thesis also introduced a test system with the test suite produced by B-U method. It describes every module of the system and some programs in detail. In the last part of the thesis, Linux host, Quagga and a kind of router were tested by this system. By analyzing the test result, we can see that this test system is stable and reliable and the B-U method is effective.
