Olivier Bertin, Jean Paul Chobert, Olivier Maurel, Alain Pruvost: Method for preempting connections in high speed packet switching networks. International Business Machines Corporation, November 11, 1997: US05687167 (184 worldwide citation)

High speed network nodes can establish new connections by preempting existing ones when insufficient bandwidth is available in the network. Numerous preemption priorities are arranged in a limited number of groups and a median priority level is defined within each group. This median, stored in the t ...

Olivier Bertin, Olivier Maurel: Method and system for improving the processing time of the path selection in a high speed packet switching network. International Business Machines Corporation, Gerald R Woods, February 4, 1997: US05600638 (119 worldwide citation)

The routing paths between origin and destination nodes in a packet switching network are selected more efficiently by reducing the total number of links potentially visited by the routing algorithm. The path selection technique involves two phases, the first phase for principal links identification, ...
