Benchmark of high performance network devices relies on high throughput traffic generator. The traffic generators are software based or dedicated hardware based. The software based traffic generators are usually running on relatively cheap commercial computer in a flexible, low cost way but suffering from poor performance. The hardware based generators can provide more precisely measured heavy traffic load but for complex traffic generation the replay mode is usually adopted. The replay mode is stateless without real interactive procedures and status verification. In this paper, a many-core processor based Traffic Multiplier working with complex stateful traffic source(s) is presented to generate pseudo-stateful heavy traffic load with normal interactive procedures. The simulated traffic pattern can be changed flexibly by adopting corresponding traffic source(s) to fit the workload diversification for the device under test. The benchmark results of many-core processor based Traffic Multiplier proofed that it can multiply complex traffic with high fidelity.
