RFC 863: Discard Protocol 🎀

okay bestie, this is RFC 863 🦋 by J. Postel at ISI, dated May 1983. It's a Standard for the ARPA Internet community, and it doesn't list anything it obsoletes or updates. 💅

Hosts on the ARPA Internet that choose to implement a Discard Protocol are expected to adopt and implement this standard. 🫶

So a discard service is a super useful debugging and measurement tool ✨. It simply throws away any data it receives. Literally just trash 🗑️💖

TCP Based Discard Service 🌸

One discard service is defined as a connection based application on TCP. A server listens for TCP connections on TCP port 9. 👑 Once a connection is established, any data received is thrown away. No response is sent. This keeps going until the calling user terminates the connection. ⭐

No response, ever. The server just catches everything and keeps it moving. 🙈

UDP Based Discard Service 🦋

Another discard service is defined as a datagram based application on UDP. A server listens for UDP datagrams on UDP port 9. 🧚 When a datagram is received, it is thrown away. No response is sent. Main character energy, but make it silent 🤫💜
