Work-conserving WRR-CSVP resource allocation in ATM networks

Abstract

This thesis investigates resource allocation at an output port of an Asynchronous Transfer Mode (ATM) switch. The resources considered are buffer space and link capacity. The objectives are to provide efficient use of resources to obtain better cell loss performance, to guarantee a minimum amount of resources to protect well-behaved traffic, and to be feasible. To this end, the Complete Sharing with Virtual Partition (CSVP) resource allocation strategy introduced by Wu and Mark [WM95] is applied to both buffer space and link capacity allocations to constitute the Work-conserving Weighted Round Robin-Complete Sharing with Virtual Partition (WRR-CSVP) resource allocation mechanism.
