Large Scale Gigabit Emulated Testbed for Grid Transport Evaluation
Résumé
Evaluating the performance of Grid applications running on high performance platforms interconnected by high speed and long distance networks with new transport services and protocols is highly required. This paper presents the eWAN integrated environment enabling large scale grid emulation at gigabit speed. It discusses features provided to control key characteristics (topology, round trip time, packet size, drop rate, link capacity) of an evaluation scenario. A method to increase the accuracy of rate control under various delay configuration is proposed and some experimental results are detailled.
