This article reviews different congestion control strategies in ATM networks. Towards this goal, we have described the problem, presented a summary of the overall congestion control strategies, and discussed the basic capabilities that could be used in the overall congestion control of a network. The set of mechanisms that constitute a general framework for congestion control consists of admission control, UPC, relative cell delay/loss priority, and flow/reactive control mechanisms. Depending on their service scenarios, the overall congestion control schemes of different networks may consist of different combinations of these mechanisms. Furthermore, different networks may realize the same mechanism (e.g., admission control, UPC, etc.) through the use of different algorithms and implementations. Therefore, it may be neither desirable nor practical to expect that standards forums arrive at agreements on the structure and algorithm for each one of the mechanisms described in the general framework. What is needed is a set of basic requirements that enables each network provider to use an appropriate subset of the general framework that suits the service scenario of its network and can smoothly interwork with other networks. The issues with solutions constituting the set of basic requirements for traffic/congestion control in ATM networks are [63]: the traffic descriptor and QOS parameters of a VC/VP, the specification of the CLP field, and the means of BCN and FCI.
