Research Topics


The Army has identified the need for open standards based multimedia terminals that integrate voice, video and data to implement multimedia applications for battlefield environments. H.323 is expected to be one of the predominant terminal standards for implementing such applications over the Army's integrated services networks of the future. Two major technical challenges that must be addressed to enable the deployment of battlefield multimedia applications over such networks are: 1) the development of end-to-end security mechanisms for multimedia streams, including authentication and privacy (encryption), to support the requirements of multimedia applications from SBU through Top Secret levels; and 2) the development of mechanisms for bandwidth-efficient transport of real-time multimedia (video, audio, data) streams with predefined QoS requirements over the rt-VBR services of a bandwidth-constrained ATM backbone network. The Phase 1 SBIR effort successfully designed and established the feasibility of building network services, called SMARTS (Secure Multimedia over ATM Real-Time Services), to address these requirements. The Phase II effort will build a functioning prototype of SMARTS by embedding its functions within commercially available implementations of the H.323 protocol stack, Gatekeeper, and Gateway. This prototype implementation of SMARTS- enhanced H.323 software will then be transitioned into a commercial product during Phase III. BENEFITS: SMARTS-enhanced H.323 software products address the requirements of Army programs such as WIN-T. This software product can be integrated within the evolving WIN architecture to enable end-to-end security and bandwidth-efficient operation of multimedia application within WIN. Non-DoD users of SMARTS range from law enforcement agencies to banks.
