RESOURCE MANAGEMENT OF AN ATM CONNECTION

摘要

Techniques of managing resource requirement of a connection in an ATM network are disclosed. The techniques add a new information element in the existing "setup" message and add a new signalling message to complement the existing Q.2725.2/Q.2963.2 (connection modify) message which is generated by the connection originating user. When a circumstance requiring a change in the resource requirement for an active connection is encountered, any network element of the network provider and the called user sends a resource change indication message to the connection owner who upon receiving such a message initiates the Q.2725.2/Q.2963.2 (connection modify) procedures, calls clearing procedures or rerouting procedures.
