Abstract

Mechanism for two portions of an application to communicate so as to facilitate a transition from synchronous to asynchronous communication. In order to prepare for a possible transition, data flow is monitored between the two portions of the application, each portion interacting with a different hardware entity. The data flow between the first portion and the second portion of the application is recorded. If the second hardware entity is not available at the time, the recorded data flow from the first portion may be replayed by the second portion of the application for the benefit of the second hardware entity. If the second portion of the application is to be reassigned to another hardware entity, the target hardware entity may be sent the second portion of the application, as well as the recorded information. This allows the target hardware entity to replay what has happened thus far for context.
