Abstract

A network for transferring information among a plurality of digital devices (12) includes a plurality of switching nodes (11) interconnected by communication links (13). Each of the digital devices is connected to one of the switching nodes over additional ones of communication links (13). Each communication link transfers information in a predetermined one of a plurality of types of communications services, with the network including at least one communication link of each service type. The digital devices and switching nodes transfer information through the network over virtual circuits, with each virtual circuit extending from one digital device, as an originating digital device, to another digital device, as a terminating digital device. Each virtual circuit defines a unitary virtual circuit path extending through at least one switching node over a plurality of the communication links without regard to the service type of the ones of the communication links included in the virtual circuit path.
