Fast Convergence and the Fast Reroute Network reliability is an important design aspect for deployability of time and loss sensitive applications. When a link, node or SRLG failure occurs in a routed network, there is inevitably a period of disruption to the delivery of traffic until the network reconverges on the new topology.
MPLS Traffic Engineering Fast Reroute Link Protection – I will explain it in plain English and the most important point of MPLS TE FRR Link Protection among other Fast Reroute mechanisms.
Fast Reroute , Fast Convergence , WRED and WFQ. You may think that why Orhan is putting all these mechanisms together. I will give you an analogy. Those who participate my talks., know that I love using analogies.
