Abstract:
1. A method of topology propagation in a distributed computing environment, said method comprising: repeatedly sending group connectivity messages from at least one group leader to identified nodes of at least one group of nodes within the distributed computing environment; discontinuing said sending of group connectivity messages during a time period of no topology change within the distributed computing environment; reinitiating repeated sending of group connectivity messages from the at least one group leader upon identification of a topology change within the distributed computing environment; wherein said discontinuing comprises for each group leader discontinuing said sending of group connectivity messages when a number of messages sent from the group leader to the identified nodes of the at least one group of nodes reaches a set limit after identification of the topology change within the distributed computing environment, and wherein the set limit is greater than one; and implementing said sending, said discontinuing, and said reinitiating without employing acknowledgement messages during said topology propagation.
