ABSTRACT:
A transformation method for network conference connections where the network operations are determined based on stored information defining the original connection and stored information defining the target connection thus affording the opportunity to advantageously reuse existing paths. The paths to be deleted and the paths to be added to effect the transformation are determined such that no path is both deleted from and added to any switch. The connection information may be stored either in a central control entity or an intra-switch path information in the individual switches of the network. In the latter case, the individual switches determine their own intra-switch path additions and deletions in a distributed fashion.
