SELECTIVE BROADCAST DATA DISTRIBUTION-SYSTEMS

This paper describes a two tier architecture for high speed data distr ibution. The architecture consists of a database interlace network whi ch distributes information from a central database to a number of serv ers, and a user interface network which distributes information from t he servers to the user terminals. The database interface network uses the Selective Broadcast technique to distribute data on a high speed c hannel. Analytical results and design examples showed that Selective B roadcast technique can provide an order of magnitude smaller response time under normal traffic conditions when compared to the nonselective broadcast technique such as the Datacycle(TM) system.
