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.

Claims

1. A method to selectively use an Application Process to both access information, and to access and interact with Minor Services that have not been referenced in the representation of the application program for the recorded Application Process comprising the steps:

a) registering Minor Services and communication primitives;

b) selecting said registered Minor Services and said registered communication primitives by chosen criteria;

c) determining which selected Minor Services and communication primitives are presently loaded;

d) loading said selected Minor Services and said selected communication primitives that are not already loaded; and

e) connecting said Application Process with said loaded minor services using said loaded communication primitives, when the Application Process requires interaction with said selected Minor Services.

2. A method to selectively use an Application Process to both access information and to access and interact with Minor Services that have been referenced in the representation of the application program for the recorded Application Process comprising the steps:

a) selecting registered Minor Services and registered communication primitives by chosen criteria;

b) determining which selected Minor Services and communication primitives are presently loaded;

c) loading said selected Minor Services and said selected communication primitives that are not already loaded; and

d) connecting said Application Process with said loaded minor services using said loaded communication primitives, when the Application Process requires interaction with said selected Minor Services.
