Considering a single download TCP connection. I am aware that modern TCP stacks will rationalize ACKs and send 1 ACK for every x packets received, thus reducing upload bandwidth requirements. Is this basically widespread and assumed that everyone has that ?
Typically you'll see one ACK per 2 packets, so you need approximately 1:50 bytes up/down ratio for the ACKs. It's possible to have middle boxes suppress some ACKs, please see thread here: https://www.ietf.org/mail-archive/web/aqm/current/msg01482.html -- Mikael Abrahamsson email: swmike@swm.pp.se
