The Discard Protocol is a service in the Internet Protocol Suite defined in RFC 863. It is intended for testing, debugging, and measurement purposes.
A host may send data to a host that supports the Discard Protocol on either Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) port number 9. The data sent to the server is simply discarded. No response is returned.
