Abstract

Scheduling mechanisms and admission policies play an important role in optimizing resource allocation in networks offering integrated services. The scheduler mediates the low-level contention for service between cells of different classes, while admission control regulates the acceptance or blocking of incoming traffic on a connection-by-connection basis. These two levels of control are of course closely related in the sense that if too much traffic is allowed to enter the network by an overly lax admission control policy, then no scheduler will be able to provide the requested Quality of Service (QoS) for all traffic classes. A functioning admission control is a prerequisite for any guarantee of cell-level QoS while its merit is to guarantee QoS efficiently and fairly. We focus on a DQDB and an ATM switch to demonstrate these principles.
