Objectively speaking, is TCP a bad protocol? If not, why does

>>55204187
TCP is better for data sensitive to errors, UDP is better for data sensitive to time. It's why games almost universally use UDP (with a custom control stack on top as you said), so the players and server dont have to wait for bad packets to retransmit. TCP would be very unfavorable in time sensitive applications.

No one uses TCP in 2016

what..

Do you even /g/?

Objectively speaking TCP is a good protocol.

>>55206398
What is used then?

TCP is a good protocol for ensuring that data arrives intact, but bad when you need events to happen in a predictable time frame. Hence why UDP is often used with a higher level protocol to ensure reliability within the constraints of a period of time. That allows servers to ensure some level of reliability while still being able to drop packets as needed.
