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 net- works with new transport services and protocols is highly required. This paper presents the eWAN inte- grated environment enabling large scale grid emula- tion 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.
