BGP4: Inter-Domain Routing in the Internet

BGP4 (Border Gateway Protocol version 4) is the de facto standard inter-domain routing protocol deployed in the Internet today. Free download BGP4 books collection in PDF, EPUB, FB2, MOBI, and TXT formats. As the means by which Internet destinations are communicated between subscribers and service providers, BGP4 provides a critical function for Internet operations. Whether you are associated with an Internet service provider or are a system administrator at an organization whose business depends heavily on the Internet, a background in BGP4 is essential. BGP4: Inter-Domain Routing in the Internet provides a practical introduction to the TCP/IP protocol suite and to routing in general. This concise guide describes the BGP protocol in clear terms and explains messages and rules for processing information through the protocol. Best deals ebooks download BGP4 on amazon.In addition to illustrating low-level details of the protocol, the author examines the conceptual way that BGP works in practical networks, the way that BGP4 interacts with other parts of a network, and other details important to its operation. This book also covers the many extensions that have been made to the original specification to increase the protocols' usability and scope of operation. Specifically, you will find coverage of such key topics as: * IP base protocol, including the packet formats, addressing and routing, and other protocol rules * Autonomous systems and the distinction between IGPs and EGPs * Distance Vector versus Link State Routing Protocols * CIDR and how it relates to BGP4 * Operational details essential to using BGP * BGP message types, path attributes, and the route selection process * Singly homed and multihomed subscribers * BGP interaction with IGP * Internal BGP scaling * TCP MD5 authentication * Other extensions to the protocol In addition, this book offers a revealing look into how large ISPs work with BGP4, including a discussion on aggregation, filtering transit customers, and public interconnect points. Numerous real-world examples throughout the book demonstrate concepts and implementation techniques. 0201379511B04062001Since its introduction in 1993, the Border Gateway Protocol (BGP) has been used extensively to allow network routers to optimize the transmission of Internet Protocol (IP) packets across the Internet. As Internet Service Providers (ISPs) and corporations seek to make their network infrastructures faster and more reliable, more administrators need to get acquainted with BGP (now in version 4). John Stewart's BGP4: Inter-Domain Routing on the Internet provides a short, authoritative guide to how Internet routing works generally, along with the specifics of the BGP4 protocol. Early sections introduce the IP protocol, the foundation of the Internet, including a concise description of IP header structure. Routing basics are also discussed, including External Gateway Protocols (EGPs) and Interior Gateway Protocols (IGPs). The book presents protocols used to determine routing efficiency, including distance-vector and linking-state routing protocols. Next, Stewart covers the Bridging Control Protocol (BGP) itself and includes discussion of BCP sessions and the message types used to send routing information between routers in BGP. A particular strength of this text is that it explains networking infrastructure with clear examples of hypothetical configurations for your ISP or organization, all using BGP. The author explains both single homing and multihoming (both with a single ISP and multiple ISPs) and explains the strategies that BGP uses to filter routing information efficiently. The book closes with new extensions to BGP, including the notion of BGP communities. This handy introduction to one of the most important--and slightly mysterious--Internet protocols is a must for any networking professional who deals with Internet routing. --Richard Dragan BGP4: Inter-Domain Routing in the Internet with free ebook downloads available via rapidshare, mediafire, 4shared, and hotfile.
