MPLS: Implementing the Technology
MPLS: Implementing the Technology is a how-to handbook for network engineers and managers charged with implementing this exciting new switching technology to build high-speed, scalable network infrastructures.
In this detailed deployment guide, networking authority Eric W. Gray explains the history of the Multi-Protocol Label Switching standard
and its relationship to existing switching protocols. This book details how MPLS provides solutions to traffic engineering routing problems and how it can also provide support solutions for virtual private networks (VPNs). Providing detailed information on the MPLS framework and its implementation, Gray??s guidebook is the ideal self-contained reference for MPLS technology.
MPLS: Implementing the Technology provides network engineers, architects, and managers with all of the material necessary to implement and deploy the technology, including:
* An in-depth survey of the ideas embodied in the technology, including label switching, label swapping and comparisons to alternate routing technologies
* An explanation of the MPLS system architecture and applicability of specific MPLS encapsulation and signaling approaches
* A comparison of MPLS and alternative approaches to solving common network problems and how MPLS is supported by technologies, including ATM, Frame Relay, Packet-on-Sonet (POS), and Ethernet
* Descriptions of how services such as QoS, traffic engineering, and virtual private networks are enhanced using MPLS
* How MPLS interacts with other technologies, including routing protocols, link-layer, and network layer technologies
* Specific deployment considerations, including tunneling, encapsulation, label distribution and loop mitigation, detection and prevention
The accompanying CD-ROM contains the entire text of the book with hypertext links, diagrams, and animations that illustrate the ideas presented in the book.
Filled with detailed information and an extensive glossary (complete with acronym definitions), MPLS: Implementing the Technology provides turnkey solutions for moving information rapidly across today??s congested networks.
