Abstract

The present invention provides a virtual network, sitting “above” the physical connectivity and thereby providing the administrative controls necessary to link various communication devices via an Access-Method-Independent Exchange. In this sense, the Access-Method-Independent Exchange can be viewed as providing the logical connectivity required. In accordance with the present invention, connectivity is provided by a series of communication primitives designed to work with each of the specific communication devices in use. As new communication devices are developed, primitives can be added to the Access-Method-Independent Exchange to support these new devices without changing the application source code. A Thread Communication Service is provided, along with a Binding Service to link Communication Points. A Thread Directory Service is available, as well as a Broker Service and a Thread Communication Switching Service. Intraprocess, as well as Interprocess, services are available. Dynamic Configuration Management and a Configurable Application Program Service provide software which can be commoditized, as well as upgraded while in operation.
