IP multicast transport based on UDP. Messages to the group (msg.dest == null) will be multicast (to all group members), whereas point-to-point messages (msg.dest != null) will be unicast to a single member. Uses a multicast and a unicast socket.
The following properties are read by the UDP protocol:
- param mcast_addr - the multicast address to use; default is 228.8.8.8.
- param mcast_port - (int) the port that the multicast is sent on; default is 7600
- param ip_mcast - (boolean) flag whether to use IP multicast; default is true.
- param ip_ttl - the default time-to-live for multicast packets sent out on this socket; default is 32.
- param use_packet_handler - boolean, defaults to false. If set, the mcast and ucast receiver threads just put the datagram's payload (a byte buffer) into a queue, from where a separate thread will dequeue and handle them (unmarshal and pass up). This frees the receiver threads from having to do message unmarshalling; this time can now be spent receiving packets. If you have lots of retransmissions because of network input buffer overflow, consider setting this property to true.
