An Approach to Service Provisioning with Quality of Service (QoS) Requirements in ATM Networks

Abstract -

We present an approach to service provisioning with Quality of Service (QoS) requirements in ATM networks.

The ATM network provides a set of services. It offers its resources (bandwidth and buffers) directly for rent, and users purchase freely these resources to meet their QoS requirements defined by the maximum call loss and the maximum end-to-end delay for each type of service. The network sets prices for its resources and users make decisions (request resources) based on these prices, their own traffic parameters, and their QoS requirements. The above procedure is iterative and is shown to converge to a resource allocation that optimizes a social welfare function consisting of the network revenue and the users' surplus.

Our approach has the following features: (i) it does not require the network to know the userUs traffic and QoS requirements; and (ii) users can determine resource requests using only their private information and the prices for resources announced by the network.

The results of this talk have been obtained in collaboration with Mr. Panagiotis Thomas.
