Abstract
A system and method for selecting a route, from within the set of network routes between the source and destination end-points, for retransmission of information initially sent via a suspected failed route such that the selected route has a minimum number of network components in common with the suspected failed route. In one aspect, the routes between source and destination end-points are grouped into a route set and placed in order in a circular list by the destination end-point. When the source end-point deems it necessary to retransmit information sent via a suspected failed route, it selects the next acceptable route following the suspected failed route from the circular list. The circular list order is determined such that adjacent routes have few common network components.
