Improving the Resilience of Fast Failover Routing
Oliver Schweiger, Klaus-Tycho Foerster, Stefan Schmid · 2021
Today's communication networks have stringent availability requirements and hence need to rapidly restore connectivity after failures. Modern networks thus implement various forms of fast reroute mechanisms in the data plane, to bridge the gap to slow global control plane convergence. State-of-the-art fast reroute commonly relies on disjoint route structures, to offer multiple independent paths to the destination.
