Sally Floyd, Matthew Mathis, Jeffrey Semke and Jamshid Mahdavi's TCP response function.


$$BW < \frac{MSS \times C}{RTT \times \sqrt{p}}$$


Where, for the TCP connection, $BW$ is the maximum bandwidth that can be reached, $MSS$ is the maximum segment size, $RTT $is the mean roundtrip time and $p$ the packet loss probability of the link. $C$ is a constant which value is $\sqrt{(3/2)}$ when the receiver acknowledges any received packet, and $\sqrt{(3/4)}$ when the receiver uses delayed acknowledgment, i.e., an ACK is sent every other received packet. This function bounds the maximum bandwidth throughput that a TCP connection can reach.

  * buffer size (in bytes)
  * packet size
  * ACKs
