A Novel Loop-Free IP Fast Reroute Algorithm SpringerLink

WebPreliminary numerical evaluations conducted on real IP network topologies suggest that rLFA significantly improves the level of protection, and most networks need only 2 - 3 new links to be added to attain 100% failure case coverage. Up to not so long ago, Loop-Free Alternates (LFA) was the only viable option for providing fast protection in pure IP and … WebFast Reroute provides link protection to LSPs. This enables all traffic carried by LSPs that traverse a failed link to be rerouted around the failure. The reroute decision is completely controlled locally by the router interfacing the failed link.

WebJun 7, 2024 · This document describes how Loop-Free Alternate (LFA) mechanism provides fast reroute of traffic in network. It also discusses two types of LFA protection- Link protection and Node protection and their applicability in order to provide minimum disruption to services because of a link or node failure. Prerequisites Requirements WebIn this paper, we present SWIFT, a fast-reroute framework which enables routers to restore connectivity in few seconds upon remote outages. SWIFT is based on two novel techniques. First, SWIFT deals with slow outage notification by predicting the overall extent of a remote failure out of few control-plane (BGP) messages.
