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 at providing the services, the mechanisms and the interactions required by multimedia applications. The architecture is based on the quality of service and communication management(More)
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 conservation, arising in multimedia communications. Speci cally, 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 with this design are described. The proposed algorithm is quickly(More)
The design and development of a complex system requires an adequate methodology and efficient instrumental support in order to early detect and correct anomalies in the functional and non-functional properties of the tested protocols. Among the various tools used to provide experimental support for such developments, network emulation relies on realtime(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. The service that this connection provides is also authorized to lose a number of objects. The POC approach establishes a conceptual link between both connectionless best-effort (CL)(More)
The study and the implementation of an adaptive service for multimedia streams based on Partial Order and partial reliability Connections (POC) is presented in this paper. A POC connection provides a service authorized to support both bounded losses and bounded disorder. Such parameters can be used to accurately define the range of conditions over which an(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)
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 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)
