Abstract

This paper presents a study of the DQDB network when one of its stations has a role of a gateway. Under this contest, some of the segments generated by each station are destined to another network. These segments are switched in the gateway, which is a DQDB station. In particular we study the effect of the physical location of the gateway on the performance. We present the traffic workload and positioning policies for the gateway for two cases. The first deals with a case of constant gateway utilization, while the second considers variable gateway utilization. In the latter case, we define a performance measure, which is shown to be optimized by utilizing our policy. Simulation results show that the performance measure is reasonable and bad positioning leads to unfairness conditions
