Patent ID: 7079535

Claim:
An improvement in a method for communication in a computer network to a plurality of receivers comprising: terminating a multicast session at an official release time associated with a multicast message with every member of a multicast group, including a sender and every intended receiver, by letting a receiver decide at the official release time that a multicast session has been successfully completed when all of the following conditions are met: (i) neither the receiver nor a local communication manager has received any fault detection report from local or remote fault detectors, or where the receiver or local communication manager has received fault detection reports from the local and/or remote fault detectors, but judged that the faults detected could not have impacted the correctness of the multicast; and (ii) the receiver has received the multicast message and returned an ACK-message; and (iii) the receiver has not received any cancellation notice from the sender.
