eWAN

Presentation

eWAN is an high performance network environment emulator written by Cyril Otal, Olivier Glück ans Pascale Primet.
It take places in the research effort on computer grids, aggregations of computer ressources inter-connected by a wide area network. eWAN offers an emulation framework needed by experiments in this field, bringing a great flexibility, a high level of performances and a precise control. It can be divided into two main parts: an interface for creation of simple topologies and an engine deploying every sort of topologies. A research paper is available here
