Abstract :
This paper is about the conflicts between two multiservice network architectures and to some extent, the data transfer perspective for congestion control, in the context of an Internet with some (or most) paths provided by underlying ATM. In the limit, we believe that networks will have excess capacity, and that this will be the model for all traffic control-hence traffic control is about finding the operating point for a fair share of the network. The conflicts between the emerging multiservice model for the Internet, which could operate in this future, and that for ATM, which address a bandwidth limited scenario, arise because we foresee a period during which ATM available bitrate will be used as part of Internetwork paths, the rest of whose hops will either be best effort, or some new sub-service of integrated services internet, but that each is being designed with a view to being the all pervasive model, and not running recursively above the other
