new thread: QoS, latency, bandwidth and the FCC/net neutrality debate

Tue Nov 28 14:50:49 MST 2017

TCP would not solve the issue. Think about constantly having to ask the
person on the other end of a phone conversation to repeat themselves
because the sound kept dropping. That would drive you be insane. That is
very much like TCP. Voice and Video traffic simply will not work in that
scenario.

You are right ethernet was not designed for voice and video in mind, but
that is where we are at and it is not changing.
