The proportional differentiation model is receiving a lot of attention recently as an effective solution for quantitative service differentiation in IP networks, we introduce the proportional differentiated service and its general framework. This general framework for proportional differentiated service in an IP network consists of three major modules at routers: the packet dropper, the packet scheduler, and the proportional policy unit. In this paper, we propose an extended framework for the proportional differentiated service based on the combination of TCP congestion control (TCC), active queue management (AQM), and packet scheduling to provide a unified, simple, robust, and scalable framework. In our opinion, an appropriate combination of the packet dropper and packet scheduler at intermediate router and the TCC reaction at source/sink system would provide an effective solution for the proportional differentiated service. © Springer-Verlag Berlin Heidelberg 2005.
