A tutorial and complete description of the core concepts and real-world applications of IP multicast, one of the most effective solutions alleviating network congestion. The author, one of the key technologists in multicasting, describes a series of multicast applications and shows how they can be used to improve business processes and information dispersal without causing network infrastructure overload.

Get a clear picture of IP Multicast applications for delivering commercial high-quality video services This book provides a concise guide to current IP Multicast technology and its applications, with a focus on IP-based Television (IPTV) and Digital Video Broadcast-Handheld (DVB-H) applications—areas of tremendous commercial interest. Traditional phone companies can use IP Multicast technology to deliver video services over their networks; cell phone companies can use it to stream video to handheld phones and PDAs; and many cable TV companies are considering upgrading to IP technology. In addition to applications in industries seeking to provide high-quality digital video and audio, there are numerous other practical uses: multi-site corporate videoconferencing; broad distribution of financial data, stock quotes, and news bulletins; database replication; software distribution; and content caching (for example, Web site caching). After an introduction that gets readers up to speed on the basics, IP Multicast with Applications to IPTV and Mobile DVB-H: Discusses multicast addressing for payload and payload forwarding Covers routing in a variety of protocols, including PIM-SM, CBT, PIM-DM, DVMRP, and MOSPF Discusses multicasting in IPv6 environments and Multicast Listener Discovery (MLD) Features examples of IP Multicast applications in the IPTV and mobile DVB-H environments Includes reference RFCs and protocols placed in the proper context of a commercial-grade infrastructure for the delivery of robust, entertainment-quality linear and nonlinear video programming This is a concise, compact reference for practitioners who seek a quick, practical review of the topic with an emphasis on the major and most often used aspects of the technology. It serves as a hands-on resource for engineers in the communications industry or Internet design, content providers, and researchers. It's also an excellent text for college courses on IP Multicast and/or IPTV.

Your best source for powering up your network with IP multicast applications Videoconferencing, video broadcasting, collaborative applications, push technologies . . . these and other new-wave networking applications are changing the way business is done. And it's your job to make sure that your company's network is equipped to handle them. This comprehensive guide gets you quickly up to speed on all technical aspects of IP multicasting-the key to delivering high-performance multimedia applications. In IP Multicasting, author Dave Kosiur clearly describes the differences between unicasting and multicasting, how multicasting works, and how it can be used to deliver the new generation of business applications. He explains the protocols and systems associated with multicasting, tells you how to prepare your network for multicasting, and what to look for when buying and upgrading network infrastructure equipment and software to ensure optimal performance. He also arms you with: * Proven implementation strategies * Everything you need to know about routing for IP multicasting * All about RTP, RTCP, RTSP, and other transport protocols * Expert guidance on integrated network services and QoS * Critical reviews of the latest multicasting software and applications. IP Multicasting is your best source for the technical know-how you need to provide your users with the sophisticated networking capabilities they demand.

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

Next-generation Internet providers face high expectations, as contemporary users worldwide expect high-quality multimedia functionality in a landscape of ever-expanding network applications. This volume explores the critical research issue of turning today’s greatly enhanced hardware capacity to good use in designing a scalable multicast protocol for supporting large-scale multimedia services. Linking new hardware to improved performance in the Internet’s next incarnation is a research hot-spot in the computer communications field. The methodical presentation deals with the key questions in turn: from the mechanics of multicast protocols to current state-of-the-art designs, and from methods of theoretical analysis of these protocols to applying them in the ns2 network simulator, known for being hard to extend. The authors’ years of research in the field inform this thorough treatment, which covers details such as applying AOM (application-oriented multicast) protocol to IPTV provision and resolving the practical design issues thrown up in creating scalable AOM multicast service models.
