Design Of HINOC2.0 MAC Protocol Conformance Testing System

HINOC2.0 is a broadband access technology with independent intellectual property rights in China.HINOC2.0 technology can make full use of the existing CATV network to provide users with Gigabit high-speed broadband access.In March 2016,HINOC2.0 protocol was officially released as broadcast television industry standard,and the first commercial chip of HINOC2.0 was released at the same time.In June 2017,HINOC testing network was deployed on a large-scale in Jiangsu province,marking the phased achievements of the industrialization of HINOC2.0.With the continuous industrialization of HINOC2.0,more and more equipment manufacturers will participate in the research and development of HINOC2.0 devices.In order to ensure the interconnection and interoperability between HINOC2.0 devices produced by different manufacturers,these devices must be tested for protocol conformance before entering the network,that is,to test whether the external behavior of these devices is in conformity with the HINOC2.0 protocol specification.Therefore,the research of HINOC2.0 MAC protocol conformance testing system is of great significance for the industrialization of HINOC2.0.The main content of this thesis is to study the design and implementation of HINOC2.0 MAC protocol conformance testing system.Firstly,the protocol of HINOC2.0 and the basic theories of conformance testing is introduced,including the networking mode,protocol stack,acceptance and maintenance mechanism,as well as the TTCN-3 language.Secondly,the requirements of the HINOC2.0 MAC protocol conformance testing system are analyzed in detail,based on the understanding of the HINOC2.0 MAC protocol and the conformance testing theory.Then,the overall structure of the testing system is proposed according to the conformance testing model.Thirdly,based on the in-depth analysis of the time delay of the testing system,the time delay compensation method is designed.Also,the software development environment(TITAN based conformance testing development platform)and development process of the testing system are introduced.Then,the modules of the testing system were designed based on the fully understanding of the requirements of the testing system,including the testing system interface,HINOC transceiver platform,abstract test suite,as well as the codec entity and system adapter of the automated testingplatform.Finally,the function of each module of the testing system is verified in detail,and the conformance testing is performed on the prototype machine.The test results verify the correctness and effectiveness of the HINOC2.0 MAC protocol conformance testing system designed in this thesis,which lays the foundation for the follow-up HINOC2.0 device conformance testing.
