DiscardUDPClient

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 {@link org.apache.commons.net.DatagramSocketClient#open open } and call {@link #send send } to send datagrams to the server After you're done sending discard data, call {@link org.apache.commons.net.DatagramSocketClient#close close() } to clean up properly.
