Multipath Routing Scheme for Link Failures in Broadband Communications

Free registration required

Executive Summary

Broadband communications are concerned with various types of failures, varying from single link failures such as fiber cuts, inline equipment breakdown to multiple network failures which significantly affects the backbone of the Internet. Alternative routing schemes and backup methodology is needed to recovery from link failures. In this paper, the authors propose a multipath routing schemes for various levels of link failures such as single link failures, multi-link failures, server and major link failures. They propose the various recovery methods for link failures in different types of networks such as Ethernet, ATM, to improve the QOS of Telecommunication.
