ABSTRACT:
A system for receiving data which is destined for station facilities on a ring-topology network includes a forwarding data channel for establishing data communication between the ring-topology network and the facilities. A station memory for selectively holding data to be transmitted from the facilities over the forwarding data channel and onto the network is also connected to the channel. Additionally, a processor, which generates and continually updates an instruction data frame with address information about the facilities is connected to the station memory. A switch interconnects the forwarding data channel with the ring-topology network to selectively receive data onto the station's channel from the network. A content addressable memory (CAM), which is also connected with the forwarding data channel, receives instruction data frames from the processor, via the station memory over the channel, to control the switch in accordance with address information contained in the instruction data frame.
