This paper describes the implementation of a broadcast service as a basic service of the JRC packet switched network. In order to lay the basis for the remainder of the paper, the implementation of the network itself is briefly described. This already contains novel features, such as the establishment of logical paths between the nodes using a multiline protocol. As well as introducing the algorithms used to implement the service itself, the way in which the service is used by the network will also be described. This use is a first step towards making the network transparent to a terminal user, and the broadcast can make the packet switched network logically compatible with local area and satellite networks. The interface that the service gives towards applications programs is then presented. To give some idea of the power of such a service, the current use of it by applications programs is then described. This includes such areas as load sharing for multiple access to the same time sharing system. Finally, some of the plans for exploitation of this service in the near future are described.
