Server—based local recovery for reliable multicast will perform efficiently only when sufficient processing and buffering resources are available at the servers. In this paper we examine the buffer requirements of servers for reliable multicast. We show ...

Multicast is an efficient communication technique to save bandwidth for group communication purposes. A number of protocols have been proposed in the past to provide a reliable multicast service. Briefly classified, they can be distinguished into sender-...

The use of proxies for local error recovery and congestion control is a scalable technique used to overcome a number of well-known problems in Reliable Multicast (RM). The idea is that the multicast delivery tree is partitioned into subgroups that form ...

Recently, several schemes have been proposed that address the problem of scalable reliable multicast using router assistance. These include LMS, PGM, AIM and OTERS, among others. While these schemes (arguably) achieve significantly better performance ...

Several architectures have been recently proposed to support IP mobility. Most studies, however, show that current protocols, in general, fall short from satisfying the performance requirements for audio applications. In this study, we propose a ...

In this paper, we address the geocasting problem for cellular mobile networks. The crucial components to support geocasting services are, the geolocation mechanism, dispersion of the geolocation information, and geocast message routing and delivery. We ...

We describe Fair Layered Increase/Decrease with Dynamic Layering (FLID-DL), a new multi-rate congestion control algorithm for layered multicast sessions. FLID-DL generalizes the receiver-driven layered congestion (RLC) control protocol introduced by ...

Multicast flow (congestion) control establishes a data rate for a multicast session based on prevailing bandwidth availability given other network traffic. This rate is dictated by the sender's path to the slowest receiver. This level of performance, ...

This work deals with the multicast transmission of data using multiple multicast groups. One reason to use multiple groups is to address the potential heterogeneity of receivers. But there is a risk that some of the groups are not used and sending data ...

Deployment of multicast routing services in corporate networks and Internet Service Providers is still tentative. Among other problems, there is a lack of monitoring and management tools and systems. Previous work in multicast management has failed to ...

Replication is known to offer high availability in the presence of failures. This paper considers the case of a client making invocations on a group of replicated servers. It identifies attributes that typically characterise group invocation and replica ...

We examine the use of a hop-limit constraint with techniques to provide survivability for connection-oriented ATM group communications. A hop-limit constraint is an approach that has evolved from solving point-to-point routing problems but has not been ...

Delivering data to on-line game participants requires the game data to be “customized” in real-time to each participant's characteristics. Using multicast in such an environment might sound contradictory. But multicast is a very efficient communication ...
