This article investigates the unfairness and throughput deterioration phenomena in distributed queue dual bus (DQDB) with slot reuse (DQDB-SR), and then proposes a bandwidth control method to prevent the phenomena. DQDB-SR is generally implemented by introducing erasure nodes which divide the network into multiple segments. When the offered load exceeds the maximum throughput level of DQDB-SR, requests from downstream segments begin to flow towards their upstream segments. This request overflow incurs a segment unfairness which forces stations on the upstream segments to be starved in access to the network. The efficiency of slot reuse will then decline, which leads to a throughput deterioration. We apply the bandwidth balancing mechanism and the access protection scheme (APS) used in DQDB to overcome these problems, and compare their performance under various workload types. Simulation results show that the APS is quite suitable for the bandwidth control to improve the performance of DQDB-SR at overload conditions.
