public class DiscardUDPClient

extends DatagramSocketClient

The DiscardUDPClient class is a UDP implementation of a client for the Discard protocol described in RFC 863. To use the class, just open a local UDP port with open and call send to send datagrams to the server After you're done sending discard data, call close() to clean up properly.
