Abstract : It is now quite agreed that the IP layer should provide more sophisticated services than the simple best-effort service to meet the application's quality of service requirements. Different proposals for improving the IP stack have been proposed but their deployment on experimental network shows different scaling problems. In this paper we present a new differentiated service scheme called ``Equivalent Differentiated Services''. The main features of the EDS scheme is that it allows to differentiate an arbitrary number of traffic classes without giving an absolute better service to any. EDS is simple, robust and scalable and provides no absolute guarantees in delay or loss rate to individual flows or aggregates. EDS acts as a network layer protocol and needs some adaptation done by an end-to-end transport layer. We present the EDS model, then we examine the implementation, simulation and validation issues.
