Résumé
Multiprotocol Label Switching (MPLS) is now a widely
deployed technology, which addresses a variety of issues,
including traffic engineering, Quality of Service, Virtual
Private Networks, and IP/ATM integration. MPLS: Technology
and Applications is the first book that provides a detailed
analysis of the architecture, protocols, and application of
MPLS.
Written by experts who personally authored key parts of the standard, this book will enable network operators and designers to determine which aspects of networks would benefit from MPLS. It is also a definitive reference for engineers implementing MPLS-based products.
Features:
- Covers major applications of MPLS: traffic engineering, VPNs, IP/ATM integration, and QoS
- Describes all the major protocols that comprise MPLS, including LDP, RSVP, and CR-LDP
- Goes beyond the RFCs to explain how and why key design decisions were made
- Provides a complete discussion of constraint-based routing
