Wireshark · Wireshark-users: Re: [Wireshark-users] TCP windows update

[Martin Visser <martinvisser99@xxxxxxxxx>]

Absolutely. Most TCP stacks open with a smallish advertised TCP window
and then embiggen it. (Whether they are actually changing available
buffers I don't know, but it was they advertise).

Many traffic shaping device employ techniques that alter ACKs and the
advertised to try and smoothly control traffic control without
discards.
