Multicast based audio/video collaboration system is one of representative applications in next generation internet. Adopting multicast technique could save bandwidth for multipoint-to-multipoint audio/video communication. Lack of ubiquitous native multicast limits the application, and current multicast based A/V collaboration systems lack effective control mechanism. This paper introduces one c...

Multicast communication is a signiicant operation in multicomputer systems and can be used to support several other collective communication operations. Hardware implementation is a viable solution to develop a low latency multicast algorithm. In this paper , we present a new multicast routing algorithm for two-dimensional meshes. The algorithm uses worm-hole routing mechanism and can send mess...

Group communication in wireless multimedia networks must consider the Quality of Service (QoS) parameters for efficient and quality aware multicast route computation. QoS parameters such as bandwidth, channel reliability, buffers, delays, jitters, etc. play a vital role in wireless multimedia networks. Multicast tree development for group communication must press for more than one or two QoS pa...

OMG has published an unreliable multicast specification for distributed applications developed in CORBA (UMIOP). This mechanism can be implemented based on IP Multicast, a best-effort protocol, which provides no guarantees about the message delivery. However, many fault-tolerant or groupware applications demand more restrictive agreement and ordering guarantees (for instance, reliable multicast...

Reliable multicast protocols are becoming an essential element in distributed applications such as interactive distance learning applications. However, the existing implementations of reliable multicast protocols are not sufficient to satisfy the group communications requirements of some distributed applications. Our experience of using number of multicast protocols in IRI distance learning app...

A multicast communication source often needs to securely verify which multicast group members have received a message, but verification of individually signed acknowledgments from each member would impose a significant computation and communication cost. As pointed out by Nicolosi and Mazieres [NM04], such cost is minimized if the intermediate nodes along the multicast distribution tree aggrega...

RSVP version 1 has been designed for optimally support multicast. However, in reality multicast is being used much less frequently than anticipated. Still, even for unicast (one sender, one receiver) communication, full−fledged multicast−enabled RSVP signaling must be used. As pointed out in the NSIS requirement draft, multicast would not be necessarily required for an NSIS signaling protocol. ...

In this work, we propose a Two-tier OverlayMulticast Architecture (TOMA) to provide scalable and efficient multicast support for a variety of group communication applications. In TOMA, Multicast Service Overlay Network (MSON) is advocated as the backbone service domain, while end users in the access domains form a number of small clusters, in which an application-layer multicast protocol is use...

The importance of computer applications and telecommunication services relying on eecient multi-destination communication is growing rapidly. It is now likely that a signiicant portion of the overall traac in future communication environments will be of the multi-destination type. At the same time, lightwave technology is emerging as a promising candidate for implementing the next generation of...
