IPv6 is the core technology of the next generation Internet, and network protocol testing is a powerful tool to ensure the smooth operation of the network. Zheng Hongxia's master thesis studies the conformance testing of IPv6 protocol, focusing on the design method of test cases, and its topic selection has important practical value.

On the basis of summarizing and analyzing the previous work, combined with the scientific research background, this paper selects the key work and puts forward a new design method of IPv6 protocol conformance test cases. By applying this method, the generation of test sequence of pre-test step and post-test step can be optimized, and a simple test case structure composed of pre-test step and test body can be obtained.

The evaluation index and calculation method of test cases are put forward, and the advantages of the new test case design method are analyzed quantitatively. Using the test case design method proposed by the author, the test sets of ICMPv6 protocol, IPv6 PMTU protocol, addressing protocol, IPSec protocol and conversion mechanism protocol are designed. In the test practice, it is verified that the new test case design method can simplify the test sequence, shorten the test execution time and improve the test efficiency.

The work of this paper shows that the author has mastered the basic theory and professional knowledge in related fields, has strong scientific research ability, and has achieved some innovative and practical research results in the design of network protocol conformance test cases.

The paper is clear in organization, clear in description, concise and fluent, and well combined with theory and practice. Reach the academic level of master's degree thesis and agree to defend the thesis.
