IP Switching and Routing Essentials: Understanding RIP, OSPF, BGP, MPLS, CR-LDP and RSVP-TE (Paperback)

Product Description
The only complete source of information on IP switching and routing technologies
A master at distilling complex need–to–know networking technologies into a clear, to–the–point narrative, proven author Stephen Thomas now tackles IP switching and routing––the backbone of all Internet communications. He presents all the relevant technologies in the context of real–world applications, offering concise explanations and over 150 illustrations that make complex topics easy to understand. An invaluable resource for network managers and service provider professionals, this book delivers complete coverage of routing technologies––distance vector, link state, and path vector––as well as the full roster of Internet standard routing protocols: Routing Information Protocol (RIP), Border Gateway Protocol (BGP), and Open Shortest Path First (OSPF). The text then documents advances that enable Multi Protocol Label Switching (MPLS), including the MPLS architecture, its interaction with standards routing protocols, Constraint–Based Label Distribution Protocol (CR–LDP), and traffic engineering extensions to the Resource Reservation Protocol (RSVP–TE).

The most complete source of information on IP switching and routing technologies

The job of delivering data efficiently over the Internet can be very complex and requires a sound understanding of the network routing protocols. This invaluable resource delves into the heart of the Internet, uncovering how this network delivers data from one location to another. Stephen Thomas explores all of the relevant technologies behind IP switching and routing, offering concise explanations and nearly 300 illustrations to help make the material easier to understand.

The book begins with an introduction to the basic concepts that are critical to the Internet and takes an in–depth look at the Internet Protocol (IP) and the UDP and TCP transport protocols, including recent advances such as differentiated services forwarding and explicit congestion notification. This is followed by an examination of the Internet′s three standard routing protocols: Routing Information Protocol (RIP), Border Gateway Protocol (BGP), and Open Shortest Path First (OSPF). Thomas also provides detailed coverage on how these protocols are actually used in real networks, as well as their syntax and semantics. He then shifts to IP switching, describing the latest advances that enable Multi Protocol Label Switching (MPLS); coverage includes label switching over ATM, frame relay, and generic networks, interaction with standard routing protocols, Constraint–Based Label Distribution Protocol (CR–LDP), and the Resource Reservation Protocol with Traffic Engineering extensions (RSVP–TE).

An essential manual for network managers and service provider professionals, this book:
∗ Delivers complete coverage of routing technologies including distance vector, link state, and path vector
∗ Discusses the full roster of Internet standard routing protocols
∗ Provides complete coverage of label switching and MPLS, including network performance gains and traffic engineering applications
∗ Examines the two common alternatives for exchanging label information: LDP and RSVP–TE

Nowhere do we find discussion of how addresses are allocated. You get a (good) summary of a number of RFCs about routing protocols, but you don't get the bit that makes it all work between the protocols - the configuration of addresses, link weights, policy etc. At all levels, the book is incredibly terse about explaining both the fundamentals and the practicalities of addressing and configuration at every level. How does an interface know its link layer address even before it can tell other nodes (ARP isn't even mentioned, let alone MAC address allocation to manufacturers)? How does an interface know its IP address? For those of us that have configured machines it's obvious, but a book is meant to explain how it works? How does a node know its AS number or the area it's in, how do we ensure uniqueness of all these identifiers? The relevance of IP address prefix summarisation isn't explained in the context of routing (CIDR isn't mentioned). Yes, all these types of addresses are mentioned, but the depth required in the context of the particular routing protocols that depend on them is completely missing in the body of the book. Yes, he explains that IP addresses identify interfaces, but he doesn't explain the significance of this in routing terms - distinguishing a hop across the interfaces of a machine against one between the ends of a link, for instance. In describing the OSPF protocol, we are told one of the router's interface addresses identifies the router, but not whether it always has to be the same one, or why. We are told the link state ID uniquely identifies each link in the OSPF protocol, but not how all other nodes identify whether two nodes at either end of a link are talking about the same link even though they may use completely different types of addressing for it. We are told that OSPF messages are within IP datagrams, but not how these IP datagrams are routed in a network that is using these messages to work out how to route IP. We are told nodes can see all ASs on a BGP path so they can apply policy about any AS, but not how I know which network operator each AS no. represents (the RIPE database etc isn't mentioned). It isn't explained how label switched look-ups know what to put in the destination link layer address of the frame being forwarded (again the link layer is hardly mentioned - strange for a book on routing). Each chapter of the book is divided into a high level explanatory half, then an introduction to the protocol format under discussion. This isn't enough. The protocol description needs supporting by prior discussion of configuration and what processing the protocol causes. By the end of the book the protocol descriptions just degenerate to lists of explanation of the options in numerical order, with little attempt to even group the explanation into meaningful order or to link them back to the higher level explanation. The book is certainly comprehensive in its coverage, but at the expense of half explaining everything. At least I now know what I need to know more about.
