Hierarchical approach for the bandwidth allocation, management and control in B-ISDN

This paper adopts a hierarchical multilayer/ multilevel approach for the allocation, management and control of B-ISDN resources. This approach seems appropriate to present a vertical decomposition of control layers, having different time-scales in addition to a horizontal decomposition, derived from the geographical distribution of control units. The paper outlines the layers proposed and explains the integrated structure derived. For virtual path allocation and management a Linear Programming model is derived. For connection admission control we suggest schemes which can handle connection types having different quality of service requirements. In addition, as fast and a fair dynamic cell-rate control scheme is presented.
