Testing and deploying mobile wireless networks and applications are very challenging tasks, due to the network size and administration as well as node mobility management. Well known simulation tools provide a more flexible environment but they do not run in real time and they rely on models of the developed system rather than on the system itself.(More)
In this paper, we address the problem of a temporal signature c onservation, arising in multimedia communications. Speciically, we are interested in the problem of the ow reconstitution and variable end-to-end delay compensation at the receiver end-system. Requirements and algorithm associated w i t h t h i s d e s i g n are described. The proposed(More)
In this paper we present the basic principles of a general architecture for distributed multimedia applications support over ATM-based networks. The architecture is aimed a t p r oviding the services, the mechanisms and the interactions required by multimedia applications. The architecture i s b ased on the quality of service and communication management(More)
This paper describes an enhancement of content access Quality of Service in peer to peer (P2P) networks. The main idea is to use an erasure code to distribute the information over the peers. This distribution increases the users' choice on disseminated encoded data and therefore statistically enhances the overall throughput of the transfer. A performance(More)
This paper deals with the improvement of transport protocol behaviour over the DiffServ assured forwarding (AF) class. The assured service (AS) provides a minimum throughput guarantee that classical congestion control mechanisms, like window-based in TCP or equation-based in TCP-friendly rate control (TFRC), are not able to use efficiently. In response,(More)
This study addresses the end-to-end congestion control support over the DiffServ Assured Forwarding (AF) class. The resulting Assured Service (AS) provides a minimum level of throughput guarantee. In this context, this paper describes a new end-to-end mechanism for continuous transfer based on TCP-Friendly Rate Control (TFRC) originally proposed in [11].(More)
This article proposes the Implicit Packet Meta Header (IPMH) as a standard method to compute and represent common QoS properties of the Application Data Units (ADU) of multimedia streams using legacy and proprietary streams' headers (e.g. Real-time Transport Protocol headers). The use of IPMH by mechanisms located at different layers of the communication(More)
This paper presents a novel e-learning platform called IREEL. IREEL is a virtual laboratory allowing students to drive experiments with real Internet applications and end-to-end protocols in the context of networking courses. This platform consists in a remote network emulator offering a set of pre-defined applications and protocol mechanisms. Experimenters(More)
A Partial Order and partial reliable Connection (POC) is an end-to-end transport connection authorized to deliver objects in an order that can differ from the transmitted one. Such a connection is also authorized to lose some objects. The POC concept is motivated by the fact that heterogeneous best-effort networks such as Internet are plagued by unordered(More)
