ABSTRACT: Asynchronous Transfer Mode (ATM) has been
recommended and has been accepted by industry as the transfer mode for
Broadband network. Currently, large scale effort has been undertaken both in
the industry and academic environment to design and build high speed ATM
networks for corporate bodies. These networks are meant to support both
real-time and non-real time applications with different quality of service
(QoS) requirements. The resources to support the applications QoS requirements
are typically limited and therefore the need to dynamically allocate resource
in a fair manner becomes inevitable. In this work, an evaluation is carried out
on the performance of enterprise-wide network that its backbone is based on
leased trunk. The performance of the leased trunk is evaluated when loaded with
homogeneous and heterogeneous traffic. The evaluation is carried out in order
to determine the exact effect of traffic overload on resources-trunk
transmission capacity and buffer. The aim is to define the optimum loading
level and the associated QoS parameter values. A typical network was adopted,
modeled and simulated in MATLAB environment by using Simulink tool and the
results obtained were analyzed by using Microsoft Excel.
