Abstract
When traffic of connectionless best effort protocols such as IP is carried over connec­
tion oriented protocols with guaranteed bandwidth, such as CBR connection in ATM,
the interface layer between the protocols (i.e., AAL ­ the ATM Adaption Layer) need
to specify the bandwidth requirement and the duration of the bandwidth reservation.
The purpose of this paper is to develop policies for deciding and for adjusting the
amount of bandwidth requested for a best effort connection over such networks. Our
aim is to develop such policies that achieve a good trade off between latency and
utilization. The performances of the different policies are compared by an empirical
evaluation.
1 Introduction
While connection oriented high speed networks (e.g. ATM) are expected to become
the major networking infrastructure, most applications are still based on the Internet
Protocol (IP). In order to lower entrance barriers for high speed networks, it would be
