  Reference Implementation of BHTML based on DASE (Lee & Saadawi)

  Reference Implementation of Data Carousel based on DASE (Lee & Saadawi)

The DASE architecture consists of multiple layers of services: from the top, application, APIs, resources and their management, networks, platform-dependent engines, and hardwares. We propose to develop and prototype the reference implementation of BHTML part of DASE application presentation engine. Specifically it consists of two parts: (1) development APIs based on BHTML following the definitions by DASE, and (2) proof-of-concept implementation of data carousel using BHTML for  DASE-compliant DTV receivers.

 

3) US. CECOM/Telcordia : 1999-2001

            Bandwidth Brokers for QoS Support in IP-based Networks for Integrated Desktop            Teleconferencing   (Saadawi & Lee)

It is proposed to use Bandwidth Brokers for providing assured QoS to voice/video over IP networks. This scalable approach is based on the Differentiated Services (DS) model. It enables the classification and differential treatment of aggregated flows through the IP network. It involves reservation of aggregate network resources on a per-domain basis using a sequence of Bandwidth Brokers, and using a combination of traffic marking, policing, shaping and scheduling mechanisms at edge and intermediate nodes for ensuring that end-hosts and domains do not violate traffic agreements and that in-profile traffic receives the desired QoS. The Bandwidth Broker architecture will be modular and will possess a uniform interface, which will enable its usage with applications other than MGCP/H.323.

Factor 2: Tactical/Strategic Interoperability

The Army must interface heterogeneous networks across tri-service, multinational boundaries and into the strategic base. Because the strategic base is primarily a commercial network, the tactical/strategic interface implies interconnection into commercial networks. As a result, the Army intends that all its communications will inter-operate with international communications standards. Research is needed into formal methods, protocols, and gateways for unambiguously specifying the necessary interfaces to ensure seamless interoperability among all Army and joint networks. Ultimately it would be desired to have fully integrated model of the battlefield communication network which through simulation would provide capability for the identification of potential bottlenecks, scenarios for potential algorithms failure of performance degradation, and also provide an environment for parameter studies for network performance optimization.

Factor 3: Information Distribution

Personnel in the Army must be able to access heterogeneous, multimedia information systems over wired and wireless communications channels with performance times that are acceptable to the situation at the echelon needing the information. This research area explores application level mechanisms to make more efficient use of the constrained communications channels while delivering the essential information to the warfighter in time.

Factor 4: Multimedia Concept

The Army’s multimedia communications requires integration of real-time and non-real-time traffic for point-to-point and multipoint applications. Research is needed in data compression, quality of service, resource allocation, data integrity, and synchronization problems for video, voice, graphics, and images over a mixture of tactical and strategic base communication networks.

  • Secure and Reliable Multimedia over Heterogeneous Networks (Saadawi & Lee)

 

Factor 5: Defensive Information Warfare

This technical factor evolved from the opportunity to conduct additional innovative research relevant to the scope of the ATIRP Technical Research. Particular attention was paid to high-risk research activities or those projects that have application across all technical factors. Foremost among these was defensive information warfare, which is investigating ways to protect communication networks and the information carried by them from attack. The focus of the ATIRP Defensive Information Warfare researches to protect battlefield information and tactical networks by ensuring their availability, integrity, authentication, confidentiality, and non-repudiation. This includes providing for the survivability of tactical information systems by deploying protection, detection, and response capabilities.
