Abstract: | Provision of Quality‐of‐Service (QoS) guarantees is an important and challenging issue in the design of integrated‐services
packet networks. Call admission control is an integral part of the challenge and is closely related to other aspects of networks
such as service models, scheduling disciplines, traffic characterization and QoS specification. In this paper we provide a
theoretical framework within which call admission control schemes with multiple statistical QoS guarantees can be constructed
for the Generalized Processor Sharing (GPS) scheduling discipline. Using this framework, we present several admission control
schemes for both session‐based and class‐based service models. The theoretical framework is based on recent results in the
statistical analysis of the GPS scheduling discipline and the theory of effective bandwidths. Both optimal schemes and suboptimal
schemes requiring less computational effort are studied under these service models. The QoS metric considered is loss probability.
