Abstract
At least one substitute path is provided in place of a plurality of existing paths of a network to reallocate traffic carried by the plurality of existing paths. The total bandwidth needed to carry the traffic of the plurality of existing paths is determined. A proposed route is generated from the available links in the network. A portion of the bandwidth of a proposed route may be allocated to the needed bandwidth when the bandwidth of a proposed route is greater than or equal to the needed bandwidth. When the bandwidth of the proposed route is less than the needed bandwidth, at least one further route is generated, and the needed bandwidth is divided among the proposed route and the at least one further route such that a minimum number of further routes are generated.
