A combined adaptive approach for congestion control in the transmission control protocol

Due to the fundamental end-to-end design principle of the TCP/IP for which the network cannot supply any explicit feedback, today TCP congestion control algorithm implements an additive increase multiplicative decrease (AIMD) algorithm. It is widely recognized that the AIMD mechanism is at the core of the stability of end-to-end congestion control. In this paper we describe a new mechanism. The key concept of the adaptive decrease mechanism is to adapt congestion window reductions to the bandwidth available at the time the congestion is experienced.
