Abundant content, data type and diverse members’ interests naturally lead to preference heterogeneity within a multicast session requiring frequent communication within subgroups of members sharing common interests/requirements. In this paper, we propose a topology-sensitive subgroup communication (TSC) mechanism to support efficient subgroup communications in large-scale multicast applications...

Abstract Linear broadcasting services, with a scheduled programming, constitute paramount telecommunication service for today’s society. Although the existing technology is mature, current linear broadcast systems have serious limitations when providing to moving users or placed in areas complex orography and poor signal quality. To overcome these limitations, 3GPP 5G standard has included work...

In order to enhance multicast communication, it is important to investigate effects of network coding which can be a typical application of active network. In this paper, we study the feasibility of network coding based multicast architecture from performance aspect. We first show that the network coding based multicast has not only high transmission capacity with the max-flow, which is an orig...

This paper describes the design, implementation, and evaluation of MiMaze, a distributed multiplayer game on the Internet. The major contribution of this work is to have designed and implemented a completely distributed communication architecture based on IP multicast. MiMaze uses multicast communication system based on RTP/UDP/ IP, and a distributed synchronization mechanisms to guarantee the ...

Recall that group communication provides a model of communication whereby a process can send a single message to a group of other processes. When such a message is sent to a predefined group of recipients (as opposed to all nodes on the network), we refer to the communication as multicast. Since a multicast is sent out to a specific group, it is important to have agreement on the membership of ...

Reliable multicast transport protocols support dissemination communication and their through-puts are either limited by the sender or by intermediate nodes that consolidate acknowledgements and retransmissions. RMSP is a portable reliable multicast protocol that supports collaborative communication at the session-layer level and provides higher throughput by maintaining two transport connection...

The growth in network application such as video conferencing, video on demand system real time protocol system, online shopping gamming, stock exchange and so on has generated new requirements for one-tomany or multicast communications. As the application involved in multicast communication is mostly multimedia, they require quality of service (QoS) requirements such as low end to end delay. Th...

A multicast communication is a significant operation in multicomputers and can be used to support several other collective communication operations. 2D torus network has become increasingly important to multicomputer system design because of its many features. This paper presents an efficient multicast wormhole deadlock-free algorithm that Balance Traffic Load on 2D torus network; hence the nam...

Investigate granularity, feedback rate, and feedback channel design trade-os and interactions. Fraud detection protocol Investigate alternatives for fraud detection protocols. Investigate use of existing communication channels be...
