Abstract:
1. A system comprising at least one of: a manager component of a network having programmed therein alternate routes for a destination address, such that upon failure of a first node of the network to which the destination address is initially routed, the manager component selects one of the alternate routes to route the destination address to a second node of the network; a first switch of the network having a port for each of at least a third and a fourth node of the network, such that upon failure of the third node, the first switch remaps a destination address initially mapped to the port for the third node to the port for the fourth node; a second switch of the network having an input port for each of at least a fifth and a sixth node of the network, and a visible output port and one or more other output ports to receive an expanded port range from an assigning manager component, such that upon failure of fifth node, the second switch uses the expanded port range to remap a destination address initially mapped to the input port for the fifth node to the input port for the sixth node; and wherein the expanded port range comprises an expanded location identifier (LID) mask count (LMC) range.
