Interconnected ring networks: a performance study

The authors investigate the performance of multiple ring networks interconnected via bridges to a backbone ring. The networks use the IEEE 802.5 protocol. The model characterizes the behavior of the IEEE 802.2 protocol used at the logical link control layer. The primary performance measures are throughput and delay. The network carries only interring traffic. The model considers homogeneous traffic environments. It is shown that the protocol throughput is critically dependent on the window size and the buffer size at the intervening bridges
