Abstract:
1. A method of offlining a switching component within a routing system having a switch fabric in which a set of distributed switching components provide a plurality of paths between a set of ingresses and a set of egresses of the switch fabric, the method comprising: concurrently computing adjusted spray weights for each of the switching components positioned along multiple paths in an order from the switching component to be offlined to a plurality of the switching components coupled to the ingresses of the switch fabric, wherein the adjusted spray weights are respectively computed in order at each of the switching components along the respective path of the multiple paths, and wherein the adjusted spray weights control proportions of packets to be forwarded to outputs of the switching components; applying the adjusted spray weights with the switching components along the multiple paths in a respective opposite order from the ingresses of the switch fabric to the switching component to be offlined; and switching packets through the switch fabric with the distributed switching components in accordance with the applied adjusted spray weights.
