This complete interdomain multicast deployment guide has proven solutions and configuration examples that make it a valuable reference tool. The solutions can be applied to a variety of service provider and enterprise networking professionals.

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.

The definitive guide to designing and deploying Cisco IP multicast networks Clear explanations of the concepts and underlying mechanisms of IP multicasting, from the fundamentals to advanced design techniques Concepts and techniques are reinforced through real-world network examples, each clearly illustrated in a step-by-step manner with detailed drawings Detailed coverage of PIM State Rules that govern Cisco router behavior In-depth information on IP multicast addressing, distribution trees, and multicast routing protocols Discussions of the common multimedia applications and how to deploy them Developing IP Multicast Networks, Volume I, covers an area of networking that is rapidly being deployed in many enterprise and service provider networks to support applications such as audio and videoconferencing, distance learning, and data replication. The concepts used in IP multicasting are unlike any other network protocol, making this book a critical tool for networking professionals who are implementing this technology. This book provides a solid foundation of basic IP multicast concepts, as well as the information needed to actually design and deploy IP multicast networks. Using examples of common network topologies, author Beau Williamson discusses the issues that network engineers face when trying to manage traffic flow.Developing IP Multicast Networks, Volume I, includes an in-depth discussion of the PIM protocol used in Cisco routers and detailed coverage of the rules that control the creation and maintenance of Cisco mroute state entries. The result is a comprehensive guide to the development and deployment of IP multicast networks using Cisco routers and switches.

Practical throughout, this book provides not only a theoretical description of Internet routing, but also a real-world look at theory translated into practice. For example, Moy describes how algorithms are implemented, and shows how the routing protocols function in a working network where transmission lines and routers routinely break down.

A guide to using and defining MPLS VPN services Analyze strengths and weaknesses of TDM and Layer 2 WAN services Understand the primary business and technical issues when evaluating IP/MPLS VPN offerings Describe the IP addressing, routing, load balancing, convergence, and services capabilities of the IP VPN Develop enterprise quality of service (QoS) policies and implementation guidelines Achieve scalable support for multicast services Learn the benefits and drawbacks of various security and encryption mechanisms Ensure proper use of services and plan for future growth with monitoring and reporting services Provide remote access, Internet access, and extranet connectivity to the VPN supported intranet Provide a clear and concise set of steps to plan and execute a network migration from existing ATM/Frame Relay/leased line networks to an IP VPN IP/MPLS VPNs are compelling for many reasons. For enterprises, they enable right-sourcing of WAN services and yield generous operational cost savings. For service providers, they offer a higher level of service to customers and lower costs for service deployment. Migration comes with challenges, however. Enterprises must understand key migration issues, what the realistic benefits are, and how to optimize new services. Providers must know what aspects of their services give value to enterprises and how they can provide the best value to customers. Selecting MPLS VPN Services helps you analyze migration options, anticipate migration issues, and properly deploy IP/MPLS VPNs. Detailed configurations illustrate effective deployment while case studies present available migration options and walk you through the process of selecting the best option for your network. Part I addresses the business case for moving to an IP/MPLS VPN network, with a chapter devoted to the business and technical issues you should review when evaluating IP/MPLS VPN offerings from major providers. Part II includes detailed deployment guidelines for the technologies used in the IP/MPLS VPN. This book is part of the Networking Technology Series from Cisco Press®, which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.
