public class NonBlockingTcpDatagramSocket
- extends TcpDatagramSocket
TCP based non-blocking datagram socket implementation. In order to provide a non-blocking API this implementation may drop packets if the underlying TCP transfer buffers are full.

SPLIT
public static final boolean SPLIT
- Flag indicating if split sockets should be used for TcpDatagram sockets. While this should ideally never be needed, testing on Linux has shown that under heavy packet loads the socket can appear to stall and refuse to accept or emit data. Worse still while the socket is in this state the NIC is transmitting ~300,000 packets/second, even when the process is paused CTRL+Z'd. This setting is conceptually similar to the "tangosol.coherence.datagram.splitsocket" but only applies to TcpDatagram sockets. Additionally it does not require multiple listening ports, just multiple connections.
