AntiECN marking: A marking scheme for high bandwidth delay connections

In this paper we describe a simple scheme that uses feedback from underutilized high capacity links to allow a TCP connection to aggressively increase its sending rate. The feedback is in the form of a single bit in the packet header and is given per packet. The scheme uses aggregate information to provide feedback and does not require the routers to maintain per flow state. We show through simulations that such a scheme allow TCP connections to efficiently utilize high capacity links without increasing the implementation complexity at the routers.
