The orthodox test methods defined in ISO 9646, i.e. LTM (Loop-back Test Method) and TTM (Transverse Test Method) are not catered for such router testing. Performance testing for high-speed routers demands high-efficiency in testing as well as synchronization among multi-ports. All these have spurred the research activities at Sichuan Network Communication Key Laboratory (SC-Netcom Lab), which are represented by the novel test method called DMSP-TTM (Distributed Multi-port Synchronized Parallel – TTM) and development of MPR-DCTS (Multi-Port Router – Distributed Concurrent Test System). The distributed multi-port concurrent test system under development at SC-Netcom Lab takes a two-layer structure: the upper layer formed of the Router Multi-Port Test Manager (RMPTM) and the lower layer composed of multiple “Router Two-Port Testers (RTPT)”. RTPTM deals with multi-port test issues such as RTPT configuration, test case distribution, and synchronization among multiple RTPTs. RTPT on the other hand, supports both LTM and TTM and acts either as an independent test device or the low-layer device of the MPR-DCTS. The work presented in this dissertation is f
