Fault-Tolerant IP and MPLS Networks

Rating:
Summary: Comprehensively Covers a Major Point of Failure
Review: This book should be of great interest to network engineeers, system engineers, and technical managers who want to understand the fault-tolerent aspects of packet-switched networks and how they can effectively design and deploy high-availability IP/MPLS networks.

The cost of low availability is well known. Amazon announced that on one day just before Christmas they had averaged approximaely 30 orders per second. A minute of down time on their system would then have resulted in the loss (hopefully just a delay) of about 200 orders.

This book is concerned not with the basic processing elements of a system, but with the edge and core routers that connect between the external communications system and the processing elements. It describes the theory, the accepted standards, and the practical aspects of designing a system that will continue to function despite failure of hardware or software components in the system.
