Congestion Control and Resource Management in Diverse ATM Environments

Large propagation-bandwidthproducts and diverse traffic characteristics have made traditional network congestion control and bandwidth management schemes less effective in high speed networks such as ATM. Furthermore, heterogeneities in ATM network size and the services offered must be considered in the development of effective congestion and resource control disciplines. New mechanisms for traffic and resource control must necessarily be adopted if high speed networks are to operate in an efficient manner. Various congestion and resource control schemes are surveyed and evaluated from the perspectives of high speed local area and wide area networks. They are also evaluated from a service perspective.
