Design of Broadband PLC Conformance Testing System Based on TTCN-3

Protocol conformance test plays a necessary and important role in guaranteeing that broadband PLC (Power Line Communication) devices to meet the standards and achieve interoperability. A broadband PLC Conformance Testing System is designed based on TTCN-3 framework. The implementation scheme for conformance testing platform is proposed and the module mechanisms as well as key techniques are described. Test suite are designed according to broadband PLC testing requirements, and finally test cases are executed based on testing environment constructed. The work is of significance for promoting the broadband PLC standardization and interoperability.
