The authors discuss an approach for fairness improvement in distributed queue dual bus (DQDB) network, which is a draft standard for IEEE 802.6 metropolitan area network (MAN). The DQDB medium access mechanism may be unfair for some realistic situations where both throughput and delay are dependent upon the geographic location of each node in the network. The authors analyze the asymmetric access property of DQDB and propose an approach called reservation capacity priority control (RCPC), which is both more efficient and fair for sending the segments. The RCPC allows the system to operate more uniformly and has a high degree of fairness in bandwidth sharing. The simulation results show that RCPC approach is more fair than bandwidth balancing mechanism under all traffic conditions.<
