Research output: Patent


A method for distributing messages among a group of member computing entities, which are mutually-linked in a distributed computing system. The members communicate in accordance with a communication protocol, which delivers a sequence of full-group multicast messages to all of the members in the group in an order that is uniform among all of the members. A sub-group is defined from among the members in the group, and a sub-group message is distributed to the members in the sub-group, such that the sub-group message is delivered to all of the sub-ground members in a uniform position with respect to the order of the full-group multicast messages, as well as with respect to other sub-group messages.
