This document describes a possible congestion control mechanism for
acknowledgement (ACKs) traffic in TCP. The document specifies an
end-to-end acknowledgement congestion control mechanism for TCP that
uses participation from both TCP hosts: the TCP data sender and the
TCP data receiver. The TCP data sender detects lost or Explicit
Congestion Notification (ECN)-marked ACK packets, and tells the TCP data
receiver the ACK Ratio R to use to respond to the congestion on the reverse
path from the data receiver to the data sender. The TCP data receiver
sends roughly one ACK packet for every R data packets received. This
mechanism is based on the acknowledgement congestion control in the
Datagram Congestion Control Protocol's (DCCP's) Congestion Control
Identifier (CCID) 2. This acknowledgement congestion control mechanism
is being specified for further evaluation by the network community.
