The Discard Protocol is a service in the Internet Protocol Suite defined in 1983 in RFC 863 by Jon Postel. It was designed for testing, debugging, measurement, and host-management 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. For this reason, UDP is usually used, but TCP allows the services to be accessible on session-oriented connections (for example via HTTP proxies or some virtual private network (VPN)).
