Title:
METHOD AND SYSTEM FOR AUGMENTING A COMMUNICATIONS NETWORK WITH SPARE CAPACITY
Document Type and Number:
WIPO Patent Application WO1999000913
Kind Code:
A3
Abstract:
A method and system for augmenting a communications network with spare components to efficiently re-route network traffic following a failure of one or more network components. The provisioning system of the present invention identifies components that are not configured into the communications network, but that could be configured into the communications network. The provisioning system identifies restoral routes to bypass a failed network component assuming that each of the identified components were configured into the network. The restoral routes are identified based on cost assigned to the identified components and the component currently configured into the network. The provisioning system then selects those identified components that are frequently used in the restoral routes to be configured into the communications network.
