Abstract
A protocol for achieving atomic multicast in a parallel or distributed computing environment. The protocol guarantees concurrency atomicity with a maximum of m-1 message passes among the m server nodes of the system. Under one embodiment of the protocol, an access component message is transferred to the server nodes storing data to be accessed. The first server node of the plurality generates a token to be passed among the accessed nodes. A node can not process its request until it receives the token. A node may pass the token immediately upon ensuring that it is the current expected token.
