Abstract

In one embodiment, a method generates interaction skeletons for a plurality of participating computers to inter-operate based on a multi-party interaction protocol. The method includes creating an Interaction Protocol based on an interaction process of how the plurality of participating computers interact with each other. The Interaction Protocol uses multiple Interaction Activities and multiple Transition Relations to describe the interaction process among the plurality of participating computers. The method then determines an interaction skeleton by generating multiple Participating Activities and their Transition Relations for each participating computer in the plurality of participating computers based on corresponding Interaction Activities and their Transition Relations in the Interaction Protocol. The interaction skeleton is converted into executable interaction modules. One of the interaction modules is loaded into each participating computer in the plurality of participating computers, and the plurality of participating computers use the interaction module to communicate messages.
