Abstract
A method for coordinating recursive requests and responses in the peer-to-peer processing of a distributed application across a synchronous request/response interface. The method utilizes, on each side of the interface, a decision table and a local LIFO stack of generated and received requests, responses, and input from the application. The local stack is run in a push-pop manner and assists the local decision table in conducting the peer-to-peer processing until the LIFO stack becomes exhausted. A fault on either side of the interface results in undoing the processing by unwinding each stack back to a predetermined point. If one side operates as a persistent server, its application program environment is saved from one request to another by a dynamic save and simulated return to the application. Lastly, a request/demand is substituted for a demand/request by the server so as to change the server and requester roles of either side of the interface.
