Load Balancing for Reliable Multicast

New applications emerge along with the rapid growth of the Internet. Many functionalities other than packet forwarding are being proposed to be added into routers for supporting those new applications. Those functionalities significantly improve the performances of the applications, but they incur overheads on routers at the same time. It...

Scalability and Robustness of Virtual Multicast for Synchronous Multimedia Distribution

A simple UDP packet reflector for virtual multicast multimedia transfer is extended to form a distributed system of active elements that solves the scalability problem of otherwise centralistic approach. The robustness of such virtual multicast delivery system is also discussed and shown to be better than the native multicast can...

MTCP: Scalable TCP-Like Congestion Control for Reliable Multicast

The paper presents MTCP, a congestion control scheme for large-scale reliable multicast. Congestion control for reliable multicast is important, because of its wide applications in multimedia and collaborative computing, yet nontrivial, because of the potentially large number of receivers involved. Many schemes have been proposed to handle the recovery of...

Hybrid Reliable Multicast With TCP­XM

Much work has been done on attempting to scale multicast data transmission to hundreds or thousands of receivers. There are, however, many situations where an application might involve transmission to just ten or twenty sites. The European Space Agency, for example, carries out regular multi-gigabyte bulk data transfers to a...

Enhancing Cellular Multicast Performance Using Ad Hoc Networks

Although multicast communication is well-suited to shared wireless links, receiver heterogeneity impedes the use of multicast in wireless networks. This paper examines an approach that addresses the receiver heterogeneity problem in cellular multicast with the help of an additional IEEE 802.11 ad hoc network. The basic idea is to allow...

MAC Layer Multicast in Wireless Multihop Networks

Many applications in wireless ad-hoc networks require multicast communication. In order to provide efficient multicast, various multicast routing protocols have been designed in recent years to facilitate formation of routes between multicast senders and receivers. There has also been some work to develop a suitable MAC protocol to improve efficiency...

Addressing Heterogeneity, Scalability, and Privacy in Layered Multicast Congestion Control

Multicast is attracting a resurgence of interest because it has a potential to address the explosively growing need for efficient streaming of large-volume Internet content. However, to realize the potential, large-scale multicast distribution requires effective congestion control. This paper designs SIM, a protocol that combines three distinct mechanisms (Selective participation,...
