Performance analysis of FDDI network under frequent bidding requirements

A bidding scheme is described for the fibre distributed data interface (FDDI). An analysis is presented for the throughput performance of an FDDI network under the assumption of heavy load, which allows the target token rotation time (TTRT) to be bid for and adjusted frequently as and when the access time requirements of synchronous traffic change. The authors´ results show that better throughput performance is achievable under the new bidding scheme. It is also observed that although re-bidding is desirable, escalating and uncontrolled bidding intensity may incur undue overheads that results in unacceptable throughput degradation.
