Abstract

A method for establishing and maintaining data communication between communication devices including at least one sender communication device and a receiving communication device of a multicast group which are interconnected by a communications network of switching nodes that involves determining when there is a change in the state of the multicast group. The receiving communication device normally maintains a resource reservation in response to data being substantially continuously received at the switching nodes unless there is a change in the state of the multicast group. Upon determination of the state change in the multicast group, the inventive method changes the resource reservation even while data is being continually received at the switching nodes.
