A New Framework for Classification and Comparative Study of Congestion Control Schemes of Atm Networks Thesis

Congestion and Congestion control in packet switch networks has been an active area of research for a long time. Congestion is defined as loss of network performance when a network is highly loaded. The problem of congestion control in ATM (Asynchronous Transmission Mode) has assumed a different dimension, because of the gigbit speed provided by ATM networks. Congestion control algorithms of packet switching networks, generally use the feedback information provided by the destination end system to control congestion. But in ATM networks, since the cell and compare various congestion control algorithms of ATM networks. In our work, we have proposed a new framework for the classification and comparative study of ATM congestion control schemes. The different aspects on which we have classified the algorithms are control theoretic approach, action and congestion notification. These three aspects present of the classification present a coherent framework on which congestion control algorithms are to be classified. Such an classification will also help in developing new algorithms. V" ACKNOWLEDGEMENTS I am thankful to Dr. C. Q. Yang for the support and guidance he gave me during my Master's thesis. I am very greatful for the oppurtunitv to work and learn under him. I also thank the Department of Computer Science for the financial support. members.
