Integrated Service (IntServ) can provide powerful QoS on a per flow basis but it requires routers to perform per flow admission control and maintain per flow state. Differentiated Service (DiffServ) model is more scalable, but cannot provide service that is comparable to IntServ. To achieve scalability and a strong service model, we believe that DiffServ equipped with scalable admission control is a possible solution. This paper examines some fair intelligent admission control schemes over the enhanced DiffServ [1]. Specifically, we propose two admission control schemes: random early dropping admission control and random early remarking admission control. We apply these admission control schemes to address traditional DiffServ problem concerning fairness. The simulation results demonstrate our schemes can offer a class-based fair resource sharing. Such admission control schemes can also help enforce the desired service assurances. © Springer-Verlag Berlin Heidelberg 2003.
