Discard

Encyclopedia : D : DI : DIS : Discard

The DISCARD protocol is an internet protocol defined in RFC 863. It is intended for testing and measurement purposes.

A host may send data to a host supports the DISCARD protocol, on either TCP or UDP port 9. Everything sent to the server is thrown away. No response is sent back.

Current testing and measurement of IP networks is more commonly done with ping and traceroute computer network tools which use the ICMP protocol instead of DISCARD.
