Many-Core Processor Based High Performance Traffic Multiplier

Performance benchmark of telecommunication core network 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 can only perform limited scenarios without real interactive procedures and status checking. In this paper, a many-core processor based traffic multiplier working with real applications is presented to simulate heavy traffic load with normal interactive procedures. The simulated traffic behavior can be dynamically changed to fit the workload diversification in the network. The benchmark of many-core processor based traffic multiplier proofed that it can multiply complex traffic with high fidelity.
