Design And Implementation Of Multidimensional Reconfigurable Protocol Conformance Test System

Protocol standard described in natural language is the basis of network research, and different understanding of protocol standards may lead to differences in Protocol Implementation. Protocol Testing can achieve the accuracy and validity of Protocol Implementation. Among them, Conformance Testing is the key, which can find problems at the beginning of deployment, so as to reduce the waste of time, manpower and financial resources. In recent years, research on mobile Internet, cloud computing, CCN, and SDN, results in a large number of new protocol standards. Existing Protocol Conformance Test System when adapting new protocols is a long development cycle, lower quality, high maintenance costs, etc. Therefore, protocol conformance test system must be able to rapidly and efficiently adapt to new protocols.Firstly, by analyzing needs of Conformance Test System, Protocol Conformance Testing Implementation is summarized into four dimensions:header Type dimension, test Procedure dimension, variable Parameter dimension and test Case dimension. Then, according to Extensible Modular Conformance Test Language, the paper designs and develops the three components:Test Data Generation Component, Test Execution with Evaluation Component and Test System Interface Component, in order to achieve multidimensional reconfigurable test system of scientific and correct. Finally, the paper complete the OSPFv3protocol conformance testing by refactoring four dimensions of test system, and check OSPFv3conformance test suites.Multidimensional reconfigurable test system technical difficulties are:1) the structure of the components and interfaces is easy to add, select, assembly and integration;2) packets organizational processes and linked list processing mechanism;3) test actions organizational process and multithreading management mechanisms;4) system interface operating logic and test report format design.Multidimensional Reconfigurable Protocol Conformance Test System provides an open architecture and multidimensional reconstruction program, which established a good foundation for the new information technology or new Internet protocol architecture.
