Register insertion bus (RIB) is a high-speed fiber optic network that uses a folded-bus topology and a medium access interface. The protocol is implemented with stations containing two buffers that allow packets in the network to be temporarily stored to avoid conflicts. Access to the network is gained via active taps at each station. Results show the access scheme to efficiently utilize the network without requiring the overhead associated with a train-type protocol. The protocol is scalable in both transmission speed and packet length. An increase in transmission speed results in a proportional increase in throughput. RIB favors upstream stations at high loads. Thus, extensions to the RIB access scheme that use an increased buffer size and information gathered from the network to provide a fair distributed access scheme for all loads are presented. The control is based on increasing or decreasing the time between transmissions, based on a count of network packet transmissions. Results demonstrate that a fair access to the network is achieved for all loads
