Eecient Multicasting for Interactive Multimedia Applications
نویسندگان
چکیده
A speciic class of multimedia applications is expected to be of importance for future communication networks: Multi-Party Interactive Multimedia (MIM). Based on the isolation and characterization of MIM applications, concrete network support requirements are derived in this paper. The varying degree of connectivity, the vastly diierent sizes in terms of participants and the reliance on a guaranteed Quality of Service make MIM support a diicult problem. Starting with the deenition of mul-timedia communication abstractions, principles of solutions are sketched. For an important subclass of applications a particularly eecient and practicable alternative implementation based on half-duplex channels is introduced. Finally, interfaces at both the transport and network layers are considered.

متن کاملA Review on QoS Multicast Routing Protocols for MANETs & Internet
Multicasting is a technique used for distributing data packets from one or more sources to a set of receivers on interconnected networks. Currently developing network applications bring specific quality of service (QoS) requirements like bounded delay, minimum bandwidth, and maximum data loss rate. Providing the required quality of service addresses routing and resource reservation concepts. In...
متن کاملReview of Multicast QoS Routing Protocols for Mobile Ad Hoc Networks
A Mobile Ad hoc NETwork (MANET) is consisting of a collection of wireless mobile nodes, which form a temporary network without relying on any existing infrastructure or centralized administration. Since the bandwidth of MANETs is limited and shared between the participating nodes in the network, it is important to efficiently utilize the network bandwidth. Multicasting can minimize the link ban...
