ECN is a far more efficient TCP congestion control mechanism that was incorporated in to the TCP standards in 2001 and it was meant to replace Jacobson's AIMD method.

A top-down exploration of networking using the 5-layer model and the TCP/IP stack. HTTP, FTP, DNS, BSD Sockets, concurrent servers, checksums, reliable transport with stop-and-wait, go-back-n, ...

In a 1987 paper, Van Jacobson described a method to restrain congestion: in a TCP connection, each side of the exchange estimates how much data it can have in transit (sent, but not yet ...
