Abstract : The Naval Research Laboratory (NRL) has designed and developed a flexible, low data rate network voice terminal application and a set of novel network integration techniques for supporting real-time packet voice over limited bandwidth wireless networks. The NRL Interactive Voice Exchange (IVOX) network voice application was developed to support low data rate (600-2400 bps) voice calls over a connectionless network. IVOX has been further modified to use a quality-of-service application programming interface (API) developed under the Data and Voice Integration Advanced Technology Demonstration (DVI ATD). Through use of the API, the network voice application can negotiate, establish, and maintain virtual circuit connection service for real-time, guaranteed delivery of network datagram traffic. Additional networking enhancements developed to support packet voice include: User Datagram Protocol Internet Protocol (UDP/IP) header compression, variable rate voice coding, and class-based queuing concepts. The DVI ATD Phase 2 effort demonstrated these advanced, integrated networking concepts over a constrained bandwidth wireless network to support simultaneous real-time and asynchronous datagram services.
