Uncooperative congestion control

—Traditionally uncooperative rate control schemes have implied open loop protocols such as UDP, CBR. In this paper we show that closed loop uncooperative rate control schemes also exist and that the current AQM proposals cannot efficiently control their mis-behavior. Moreover, these proposals require that AQM be installed at all routers in the Internet which is not only expensive but requires significant network upgrade. In this paper we show that management of uncooperative flows need not be coupled with AQM design but can be viewed as edge based policing question. In this paper we propose an analytical model for managing uncooperative flows in the Internet by re-mapping their utility function to a target range of utlity functions. This mapping can be achieved by transparently manipulating congestion penalties conveyed to the uncooperative users. The most interesting aspect of this research is that this task can be performed at the edge of the network with little state informati...
