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, ...

Currently, routing algorithms compute all the available paths in the network, from a source node to a destination node before selecting the optimal route. The route computation is often time and resource consuming. Some paths are not acceptable due to the particular geographical configuration of the ...

A method for operating a node in a computer network is disclosed, where the network is made up of nodes connected by links. The method has the steps: determining an alternate path for one or more links; reserving resources for the alternate path; and rerouting traffic on the alternate path in case o ...

Olivier Bertin, Claude Galand, Olivier Maurel: Dynamic bandwidth reservation for control traffic in high speed packet switching networks. International Business Machines Corporation, Daniel E McConnell, January 4, 2000: US06011804 (38 worldwide citation)

A method and system for reserving dynamically and in priority for each link of the network the exact amount of bandwidth necessary for the transmission of the network control traffic. An evaluation of the expected control traffic on each link of the network is performed in order to allocate a suffic ...
