Yiwen Wang, Yunyi Li, Xiaoting Wang, Zhao Xiaohui · 2015
Traffic generator is a key component in the verification and test platform for network switches.It can produce packets for different network protocols, and the generated traffic can simulate the real internet traffic.A novel traffic generator, different from general traffic generator structure, is implemented by software and hardware co-design methodology, which using software to generate the complex traffic types and hardware to generate corresponding packets.The proposed traffic generation solution is able to meet the requirements of the today's high-speed, high-load, complex network.The traffic generator is developed based on Xilinx Virtex-5 FPGA development board with Uniform, Poisson and MMPP traffic models at Gbps line rates, and verified on test platform.
