Managing information dissemination by satellite broadcast

An important element of the non's approach to Battlefield Digitization is the development of new systems that disseminate information by direct broadcast satellite (DBS). The Global Broadcast Service (GBS) is the premiere program providing new capabilities for data broadcasting. Techniques for enabling legacy applications to transmit data over GBS also provide guidance for developers of new information systems and providers of commercial DBS services. Unique network management requirements arise from the need to apportion communication resources to optimize the availability of critical information for the end-user. To obtain peak performance, applications that transfer data by DBS will need support to accommodate scheduling of broadcast transmissions with appropriate qualities of service. This paper describes reference models and architectures for designing DBS communication services that realize the benefits of managing access to the data broadcast. New and legacy applications are able to use standard protocols to communicate with the help of broadcast management clients that set np DBS communication sessions using mete-signaling techniques, The concepts outline how to define a broadcast service that transparently converts point-to-point application data streams into point-to-multipoint streams.
