Abstract

A system for maintaining routing tables at each router in a computer network. The system is based on (a) a feasibility condition that provides multiple loop-free paths through a computer network and that minimizes the amount of synchronization among routers necessary for the correct operation of a routing algorithm, and (b) a method that manages the set of successors during the time it synchronizes its routing-table update activity with other routers, in order to efficiently compute multiple loop-free paths, including the shortest path, through a computer network.
