This book examines multicast technology and will be a key text for undergraduate engineering students and master students in networks and telecoms. However, it will be equally useful for a wide range of professionals in this research field. Multicast routing was introduced with the advent of multiparty applications (for example, videoconferencing on the Internet) and collaborative work (for example, distributed simulations). It is related to the concept of group communication, a technique introduced to reduce communication costs. The various problems of multicast routing on the Internet are examined in detail. They include: group membership management, quality of service, reliability, safety, scalability and transport. Throughout the text, several protocols are introduced in order to analyze, compare and cover the various aspects of multicast routing.

The Internet is quickly becoming the backbone for the worldwide information society of the future. Point-to-point communication dominates the network today, however, group communication--using multicast technology--will rapidly gain importance as digital, audio, and video transmission, push technology for the Web, and distribution of software updates to millions of end users become ubiquitous. Multicast Communication: Protocols and Applications explains how and why multicast technology is the key to this transition. This book provides network engineers, designers, and administrators with the underlying concepts as well as a complete and detailed description of the protocols and algorithms that comprise multicast. * Presents information on the entire range of multicast protocols, including, PIM-SM, MFTP, and PGM and explains their mechanisms, trade-offs, and solid approaches to their implementation * Provides an in-depth examination of Quality of Service concepts, including: RSVP, ST2, IntServ, and DiffServ * Discusses group address allocation and scoping * Discusses multicast implementation in ATM networks * Builds a solid understanding of the Mbone and surveys the successes and current limitations of real multicast applications on the Internet such as videoconferencing, whiteboards, and distance learning

This volume aims to document the authors' prescription for the architecture, the way the component services are fitted together to provide collaborative tools for video, audio and shared workspaces. The authors have decided to take a new approach to the field by using a prescriptive rather than descriptive style. The text is aimed at technical readers such as developers, undergraduate or postgraduate (MSc) courses on multimedia and networking, and professionals. The subjects covered include the network requirements, the media encoding techniques including basic compression techniques, the protocols (rtp/rtcp, rsvp etc.), the distributed algorithms for synchronization, reliability, security and so on.

In the first part of the thesis, we address the optimization of multimedia applications such as videoconferences or multi-player games in which user-dependent information has to be sent from the users to a core node to be chosen, and then global information has to be multicast back from the core node to all users. For a given communication network, this optimization seeks a core node under two potentially competing criteria, one being the sum of the distances the users, the other being the cost of connecting this core node and the users with a multicast (or Steiner) tree. We first consider the problem of minimizing a weighted sum of the two criteria and propose a heuristic which rapidly computes a solution guaranteed to be within a few percent of the optimum. Then we characterize the worst-case trade-offs between the two criteria and show that there always exists a core location for which each criterion is close to its minimum value. The second part concerns the protection of multimedia streaming applications against packet losses. By adding redundancy within blocks of consecutive data packets, losses can be recovered by the receiver unless long bursts of packets are lost inside the network. It has thus been observed that splitting packet streams onto several paths typically decreases the probability of an irrecoverable loss. Whereas current approaches rely on an exact computation of the probability and are consequently restricted to very small network instances, we propose to approximate this probability by measuring the impact of the chosen routing on the peakedness of the received packet stream. The peakedness of a stream may be seen as a measure of how packets are spread over time within the stream. Numerical experiments are presented and show that our method yields good approximations of the probability of irrecoverable loss.
