Abstract : The Grid aims at expanding the cluster based parallel computing paradigm toward large scale distributed systems based on IP networks. To validate grid algorithms, evaluate their performance and to study transport and coordination protocols and grid network services, a well controlled environment is required, allowing to precisely manage the experience conditions. One of the most important issue is to emulate the potentially very high speed wide area network interconnection. This paper presents a software and hardware tool for configuring and programming a large PC cluster in a wide area network emulation instrument. High performance, fine parameter tuning and a great utilization flexibility are the main proposed features of this experimental tool. This article discusses the eWAN design principles and the first experimentations that have been done on a prototype deployed over the Grid5000 cluster at the ENS Lyon. Some usage scenarii are also proposed.
