Description
Summary:Evaluating the performance of high-speed networks is a critical task due to the lack of reliable tools to generate traffic workloads at high rates. The current open-source software tools are not suitable to deal with high-speed networks as they present poor performance in terms of generated frames per second and scarce timing/rate accuracy in traffic generation. These issues are due to the intrinsic limitations of the PC architecture, for which these tools are designed. This paper proposes a different approach based on the Intel Network Processor IXP2400. The design aims to maintain the high flexibility of PC solutions while outperforming them in terms of throughput and packet rate. This is obtained by combining a general-purpose PC with the processing units of a network processor.
