The use of broadcast techniques on the universe network

Abstract

The Universe network is being used to explore broadcasting techniques in a highly integrated computer communications experiment connecting local area networks via a broadcast satellite channel. The broadcast protocol which has been devised within the Project provides a versatile framework in which different types of broadcast applications can be carried out. The requirements and definition of this protocol are described, and details are given of how the broadcast satellite channel is used and the implementation of the protocols in the system which provides satellite access from each site. Experimental use of the protocol is also described, in particular its use for file distribution. The paper also aims to show how the protocols could be used for more advanced applications.
