Congestion avoidance in computer networks with a connectionless network layer: concepts, goals and methodology

The authors compare the concept of congestion with that of flow control and congestion control. A number of possible alternatives for congestion avoidance are identified. From these a few are selected for study. The criteria for selection and goals for these schemes are described. In particular, the authors wanted the scheme to be globally efficient, fair, dynamic, convergent, robust, distributed, configuration-independent, etc. They model the...
