Adaptive Circuit Access Control for Network Resource Management

概要

論文の詳細を見る
Circuit access control is a traffic control technique of rejecting calls arriving at a group of specified circuits to make the group free at a target scheduled time so that the capacity may be dynamically reallocated to serve other traffic demand. This technique plays an important role for resource allocation control in state-of-the-art capacity reconfigurable networks as well as for switching calls on a reserved basis in the ISDNs. In this paper, we present a novel adaptive scheme for circuit access control in order to overcome the inefficiency of the conventional deterministic scheme. The presented scheme is based only on knowledge about service time and bandwidth characteristics of calls. The transitional behavior of the circuit group under the scheme is analyzed, and the gain in utilization achieved by the adaptive scheme is examined. We treat a model of the circuit group shared by multi-slot calls with different service times, and describe the results of the transient analysis and the approximation method for evaluating the gains.
