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.

Engineering from the University of Patras, Patras, Greece,
and his M.S., E.E., and Ph.D. degrees, all in Electrical
Engineering, from the Massachusetts Institute of Technology,
Cambridge, Massachusetts. His research interests are in
stochastic control, decentralized systems, queueing and
communication networks, stochastic scheduling and resource
allocation problems, mathematical economics, and discrete
event systems.
