| The deployment of gigabit networks and
broadband services has started to support multimedia
applications, however, these gigabit networks are rarely
saturated since only a few applications are stable to stress the
network. We consider a future scenario where the use of
multimedia applications, such as audio and video teleconferencing
in a multi-user environment, is expected to grow rapidly.
Therefore, both customers and network providers, need to foresee
the performance and behavior of the network and the applications
in this scenario. From the customer's point of view, it is
important to develop procedures to perform traffic measurements
and to be able to test the local ATM equipment. In this paper we
propose a method to introduce heavy load into an ATM switch and
at the User Network Interface (UNI) for studying the performance
and forecast evoloved scenarios. In the experiments we use local
equipment (ATM switch and workstations), local network management
applications and diagnostics software. The emulated load is
generated in a workstation, introduced into the ATM switch and
intensified by replicating and re-circulating the cells. The
method presented is an easy and affordable way of performance
testing and an alternative to traffic modeling. Several
experiments have been performed and the measurements obtained are
presented. |
