Abstract
A method is disclosed for providing likely updates to views of group members in unstable group communication systems. A group message is received from a sender associated with a sending node in a network. The group message includes a message view having a counter and an acknowledgment set. The acknowledgment set identifies one or more receiving nodes to which the group message is directed. Issuance of an acknowledgment of the group message to the sending node is deferred. The group message is delivered to the receiving nodes. An acknowledgment of the message is received from one of the receiving nodes. The message view is updated by removing each receiving node that issues an acknowledgment from the acknowledgement set. The updated message view is provided to the sender.
