Network Performance Evaluation Based on Three Processes

Network performance evaluation has traditionally been done following the client/server model, using two processes to carry out the evaluation. In this paper we present a different approach. We propose an enhancement to the classical performance evaluation by using three processes: client, server, and a middle process that reports additional gauges which allow users to more accurately and rapidly detect network anomalies. For this third process we wrote two versions: one for PC-based routers, and the other for off-the-shelf wireless routers. The former version was presented in one of our previous works. In this paper, we present our experience in writing and porting our application to wireless routers. Additionally, we perform different experiments to validate the correctness of the results reported. Furthermore, we present additional experiments that illustrate another possible uses for our tool.
