Ein breitbandiges lokales Netz mit kombinierter Ring-Stern-Struktur

This paper presents a new system architecture for a wideband local area network (LAN) which consists of a combination of a ring-structured local area network and a star-shaped centrally-controlled wideband switching unit. The bit rate is 98 Mbit/s. The system uses a hybrid access scheme suitable for both circuit and packet switched communication. It incorporates a fast packet channel using the FDDI token ring protocol. The function of the station controller and the central control units are described. The system functions as a local area wideband network for high speed data communication and for the transport and switching of many high-bit-rate video channels (e.g. 34 Mbit/s).
