Understanding TCP fairness over Wireless LAN

Saar Pilosof, Ramachandran Ramjee, Danny Raz, Yuval Shavitt and Prasun Sinha

Yet another performance imparement due to the .11/TCP combination. In this case, the culprit is the AP buffer limited size. Discarding a downstream data packet has a greater impact than discarding a (down-going) ACK of an upstream flow.

The anomaly is observed, analyzed and simulated. A solution is also suggested, involving the manipulation of the TCP packets.
