Switching in IP networks - Bruce S Davie|Paul Doolan|Yakov Rekhter

Label switching, an economical and efficient technique for message forwarding in IP networks, is fast becoming a widely deployed solution for improving performance, scalability, and functionality. Written by leading experts in the field, this guide explores the underlying technology of label switching and provides a detailed analysis and comparison of approaches developed by Ipsilon, Cisco, Toshiba, and IBM. It also compares label switching with conventional routing, culminating in a discussion of the Multiprotocol Label Switching (MPLS) standard now being developed by the Internet Engineering Task Force (IETP). This book-the result of a rigorous review process by key designers-is an invaluable resource to network engineers and designers for evaluating the use of label switching in their own networks.;Content Highlights Explains the benefits and limitations of label switching technology Compares performance, scalability, and robustness of IP Switching, Tag Switching, Cell Switching Router (CSR), and Aggregate Router-based IP Switching (ARIS) Reveals how label switching simplifies IP over ATM integration problems Presents the latest snapshot of the MPLS standard, which incorporates the strengths of several of the approaches discussed "An outstanding overview and comparison of technologies that will form the foundation for the next evolution in network architecture." -Christine Heckart, Vice President, TeleChoice "A clear and authoritative review of a major advance in networking, written by some of the pioneers." -Dr. John M.
