Abstract
A group communication service is adapted for multi-point to multi-point communication. Identical message streams are received by a tier of processing servers from a tier of sources. The processing servers deliver the message streams to a tier of destinations. The group communication service enables the processing servers to deal with newly added message streams and deleted message streams while preserving total ordering.
