Active queue management and global fairness objectives

We present an active queue management policy and we study its ability to steer, in a distributed fashion, an entire TCP/IP network into global max-min fairness of its long-lived flows. A previously proposed technique, initially applicable to circuit-switched networks and feedback-based flow control networks is adapted to the realities of packet-switching and TCP flow/congestion control, together with a per-hop policy, called FairShare. The proposed solution is evaluated using several example topologies, including linear, loop, and irregular topologies as well as dynamic load fluctuations.
