Abstract
Asynchronous Transfer Mode (ATM) promises to be the ultimate internetworking technology.
Its high bandwidth uniform switching can transfer Video, Audio and text generated by a wide
variety of applications, at higher speed than available today. Because of high speed and wide
application range.; problems facing ATM is different from problems that faced conventional data
networks. Congestion is one of the major concerns facing implementation of ATM Switches as it
can cause degradation of the Quality of Services provided by the application. Congestion control
can be done by many ways and on di fferent layers of networking. examples are proper
assignment of resources(buffer and bandwidth), tuning the service Scheme, policing sources that
violate their declared traffic behavior .
In this thesis we try to control the congestion by proper design and tuning of buffering and
service scheme. A simulation Program was developed to enable LIS to simulate different
buffering and service schemes . The simulation results were used to lind how different
parameters affect both Quality of Service ( QoS) and the Utilization of A™resources. the
results were used to set the rules and requirements of the control scheme. The results expressed
the need for system capable of finding the right control parameters that will provide the required
and only the required QoS.
We proposed the use of an intelligent technique to implement this controller the requirements for
that controller were stated and an implementation was proposed . The design was tested and
enhanced to ensure its compliance to the requirements .
