Transformation method for network conference connections
First Claim
1. A method comprisingestablishing an original connection among an original plurality of user stations through a communication network,storing information defining said original connection through said network,determining a target connection among a target plurality of user stations through said network, where the union of said original and target pluralities of user stations includes at least two user stations not included in the intersection of said original and target pluralities of user stations, and where said intersection includes at least one user station,storing information defining said target connection through said network,based on said stored information defining said original and target connections, determining a set of operations on said network to transform said original connection into said target connection, andeffecting said set of operations on said network.

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.

1. A method comprising
establishing an original connection among an original plurality of user stations through a communication network, storing information defining said original connection through said network, determining a target connection among a target plurality of user stations through said network, where the union of said original and target pluralities of user stations includes at least two user stations not included in the intersection of said original and target pluralities of user stations, and where said intersection includes at least one user station, storing information defining said target connection through said network, based on said stored information defining said original and target connections, determining a set of operations on said network to transform said original connection into said target connection, and effecting said set of operations on said network.

21. A method comprising
establishing an original connection effecting an original connectivity pattern among a plurality of user stations through a communication network, storing information defining said original connection through said network, determining a target connection effecting a target connectivity pattern among said plurality of user stations through said communication network, where said target connectivity pattern differs from said original connectivity pattern, storing information defining said target connection through said network, based on said stored information defining said original and target connections, determining a set of operations on said network to transform said original connection into said target connection, and effecting said set of operations on said network.

24. A method comprising
storing information defining an original connection among an original plurality of user stations through a communication network, determining a target connection among a target plurality of user stations through said network, where the union of said original and target pluralities of user stations includes at least two user stations not included in the intersection of said original and target pluralities of user stations, and where said intersection includes at least one user station, storing information defining said target connection through said network, and based on said stored information defining said original and target connections, determining a set of operations on said network to transform said original connection into said target connection.
