Multi Protocol Label Switching (MPLS) is a breakthrough that can simplify routing and enhance network performance in a wide variety of applications, notably VPNs, traffic engineering, and Quality of Service applications. Cisco Systems, IBM, and Toshiba are a few of the companies currently committed to support MPLS as a switching standard. This is the first complete, real-world guide to implementing MPLS. Written by a leader of the MPLS Forum standards community, it will be an invaluable resource for everyone charged with deploying or evaluating the technology. Discover how MPLS simplifies routing, helping network managers avoid congestion hot spots and build networks with lower latency and greater scalability. Gray reviews MPLS system architecture and shows how MPLS can be used in diverse network environments, including ATM, Frame Relay, SONFT, and Ethernet. Learn how to leverage MPLS in delivering real-world applications. The accompanying CD-ROM contains an HTML version of the book, animations to augment the diagrams in the book, as well as internet drafts and RFCs to illustrated the ideas in the text.
