Abstract

The paper addresses the issue of reserving resources at each ATM switch along the path of a flow that requires a hard (deterministic) bound on end-to-end delay. The switches are assumed to be using Packet-by-packet Generalized Processor Sharing (PGPS) schedulers for each outgoing link. An algorithm for call admission control of these flows is proposed. Different policies for mapping the end-to-end delay requirement into service rates to be assigned at each scheduler are suggested and analyzed.
