ECMP fast convergence on path failure using objects in a switching circuit

Abstract:

A switching circuit includes circuitry configured to manage a plurality of Equal Cost Multiple Paths (ECMPs) through a plurality of shared protection group objects, wherein each of the plurality of shared protection group objects is connected to two paths in the ECMPs, and wherein a number of shared protection group objects equals a number of next-hops, cause distribution of packets based on a setting of the shared protection group object for each next-hop, and responsive to a failure of a next-hop, change the setting of the shared protection group object for the failed next-hop
