poll: have you ever designed a protocol that uses TCP or UDP directly? (vs using protocols that are based on TCP/UDP like DNS, HTTP, SSH, etc)
(you can pick more than one)
I'm so curious about what the 30% of you who are designing custom UDP-based protocols are doing, I would love to hear more!
(please only reply if you responded “yes, UDP” to the above poll)
@b0rk super simple exchange of a few bytes from application servers to a daemon which then uses the info gathered this way to talk over TCP to another service.
UDP in this case was chosen because low latency and zero wait time was preferred over guaranteed delivery
