5321815Route selection using cached partial trees in a data communications network
A process for selecting a least weight path between two nodes in a data communication network uses partial trees created and cached in prior route selection operations. All root nodes on possible paths between the two nodes are identified. Any cached tree...

5253161Method for routing data in a near-optimal manner in a distributed data communications network
A method to produce near-optimal routes for the flow of data between clusters in a distributed data communications network. A backbone traffic matrix and a backbone topology at the cluster level are used to produce minimum hop routes, minimum delay routes...

5031093System for establishing route by selecting minimum of time-independent link parameters of incremental values
A routing matrix for fixed routing is derived for a communications network having a plurality of nodes interconnected by links each having a link parameter. A second node which can be reached from a first node by a single hop is determined, and a third no...
