QoS Required by a DIS Application in a New Generation Internet

In order to distribute new multimedia applications on a high scale, the mostly used and analyzed wide area networks (WAN) are the Internet on one side and ATM based networks on the other side. One of the current research activities in the networking area consists in trying to federate the Internet new mechanisms / protocols (IP new Generation : IPnG) and the ATM ones, in order to allow applications to be guarantied with an end to end Quality of Service (QoS). Study which is presented in this paper dills with this specific activity and has been realized within a project implying a French Industrial (Dassault Electronique) and three French research Laboratories (LAAS-CNRS, LIP6) and Institute (INRIA Sophia Antipolis) ; the general goal of the project was to specify and then perform the QoS required by a distributed interactive simulation (DIS application) in an heterogeneous WAN environment : IPnG and ATM (national MIRIHADE platform, today SAFIR). Results exposed in this paper are mainly related to the QoS characterization a DIS application has to require so as to be distributed in a WAN environment ; a shorter part of the paper is dedicated to the end to end communication architecture defined within the project in order to provide a QoS matching DIS applications requirements. 1 LAAS-CNRS : Laboratoire d’Analyse et d’Architecture des Systèmes du Centre National de la Recherche Scientifique LIP6 : Laboratoire d’Informatique de l’Université de Paris VI INRIA Sophia Antipolis : Institut National de Recherche en Informatique et en Automatique de Sophia Antipolis
