Design and Implementation of Load-Balanced Multipath Self-routing Switching System

In order to ensure high quality of service (QoS) for Next Generation Network (NGN), we construct a new LoadBalanced Multipath Self-routing Switching Structure which consists of the same two multipath self-routing fabrics. The result of simulation is inspiring for achieving 100% throughput and no delay or jitter. For this reason, we start on the implementation on an Altera StratixIV FPGA. And the whole FPGA system is designed into two collaborative components: the UDP system and the register system. With two algorithms around input and output two stages, incoming traffic is transformed into uniformity and then to their final destinations. During the later period debugging, software simulation platform and automated test platform are built, which contribute to our work very much. At last, we carry out several experiments to test and verify our system. The report of the test result accords with what we expected.
