Abstract:

The Data and Voice Integration ATD is a four year program managed by the Naval Research Laboratory NRL with a goal of demonstrating integrated communication services using low bandwidth, tactical communication channels. At present, Phases I and II of a three phase demonstration have been completed. Phase I integrated real-time voice and non-realtime data services over a single link, low capacity, tactical circuit. Phase II demonstrated these services over a tactical broadcast network. Phase III will demonstrate datavoice integration with internetworking and multicast routing capabilities. This report focuses on two of the major areas of development critical to the success of this ATD. The first area is the development of voice management protocols for half and full duplex operation. The second is the development of a DataVoice Integrator DVI. The DVI design includes a Subnetwork Provider Interface SNPI, an interface to a Red Link Controller RLC, queue management, a multiplexing scheme, and a software design. The multiplexing protocol creates a unique form of link-sharing, e.i., the ability to dynamically divert bandwidth that is reserved but not currently being used to support other services.
