TCP's congestion window controls the number of packets a TCP flow may have in the network at any time. However, long periods when the sender is idle or application-limited can lead to the invalidation of the congestion window, in that the congestion window no longer reflects current information about the state of the network. This document describes a simple modification to TCP's congestion control algorithms to decay the congestion window cwnd after the transition from a sufficiently-long application-limited period, while using the slow-start threshold ssthresh to save information about the previous value of the congestion window.

TCP Westwood with Limited Congestion Window
ICACC '09: Proceedings of the 2009 International Conference on Advanced Computer ControlTCP Westwood (TCPW) is a sender side modification of TCP congestion control. It estimates the connection rate by monitoring the acknowledgment reception rate; this estimation is used to compute congestion window and slow start threshold. The sender ...
TCP and explicit congestion notification
This paper discusses the use of Explicit Congestion Notification (ECN) mechanisms in the TCP/IP protocol. The first part proposes new guidelines for TCP's response to ECN mechanisms (e.g., Source Quench packets, ECN fields in packet headers). Next, ...
