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 book proposes representations of multicast rate regions in wireless networks based on the mathematical concept of submodular functions, e.g., the submodular cut model and the polymatroid broadcast model. These models subsume and generalize the graph and hypergraph models. The submodular structure facilitates a dual decomposition approach to network utility maximization problems, which exploits the greedy algorithm for linear programming on submodular polyhedra. This approach yields computationally efficient characterizations of inner and outer bounds on the multicast capacity regions for various classes of wireless networks.

Whereas unicast routing determines a path from one source node to one destination node, multicast routing determines a path from one source to many destinations, or from many sources to many destinations. We survey multicast routing methods for when the set of destinations is static, and for when it is dynamic. While most of the methods we review are tree based, some non-tree methods are also discussed. We survey results on the shape of multicast trees, delay constrained multicast routing, aggregation of multicast traffic, inter-domain multicast, and multicast virtual private networks. We focus on basic algorithmic principles, and mathematical models, rather than implementation level protocol details. Many historically important methods, even if not currently used, are reviewed to give perspective on the evolution of multicast routing.
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.
This book discusses the fundamental concepts that are essential to understanding IP multicast communication. The material covers the well‐known IP multicast routing protocols, along with the rationale behind each protocol. The book starts with the basic building blocks of multicast communications and networks, then progresses into the common multicast group management methods used, and finally into the various, well‐known multicast routing protocols used in today’s networks. IP multicast provides significant benefits to network operators by allowing the delivery of information to multiple receivers simultaneously with less network bandwidth consumption than using unicast transmission. Applications that can benefit greatly from multicast communications and multicast‐enabled networks include audio and video conferencing, collaborative computing, online group learning and training, multimedia broadcasting, multi‐participant online gaming, and stock market trading. This book’s goal is to present the main concepts and applications, allowing readers to develop a better understanding of IP multicast communication. IP Multicast Routing Protocols: Concepts and Designs presents material from a practicing engineer’s perspective, linking theory and fundamental concepts to common industry practices and real‐world examples. The discussion is presented in a simple style to make it comprehensible and appealing to undergraduate‐ and graduate‐level students, research and practicing engineers, scientists, IT personnel, and network engineers. It is geared toward readers who want to understand the concepts and theory of IP multicast routing protocols, yet want these to be tied to clearly illustrated and close‐to‐real‐world example systems and networks.
The papers comprising Vol. I and Vol. II were prepared for and presented at the International Conference on Information Networking 2002 (ICOIN 2002), which was held from January 30 to February 1, 2002 at Cheju Island, Korea. It was organized by the KISS (Korean Information Science Society) SIGIN in Korea, IPSJ SIG DPE (Distributed Processing Systems) in Japan, the ITRI (Industrial Technology Research Institute), and National Taiwan University in Taiwan. The papers were selected through two steps, refereeing and presentation review. We selected for the theme of the conference the motto “One World of Information Networking”. We did this because we believe that networking will transform the world into one zone, in spite of different ages, countries and societies. Networking is in the main stream of everyday life and affects directly millions of people around the world. We are in an era of tremendous excitement for professionals working in many aspects of the converging networking, information retailing, entertainment, and publishing companies. Ubiquitous communication and computing technologies are changing the world. Online communities, e commerce, e service, and distance learning are a few of the consequences of these technologies, and advanced networking will develop new applications and technologies with global impact. The goal is the creation of a world wide distributed computing system that connects people and appliances through wireless and high bandwidth wired channels with a backbone of computers that serve as databases and object servers. Thus, Vol.
