Multicast Response Mode

When the PointToPointResponse boolean attribute is false, the discovery client specifies multicast mode in its requests. The discovery responder will use the existing multicast socket to send response, broadcasting it to the same multicast group as the request. As shown in the following diagram, every member of the multicast group will receive the message, but only the discovery client can make use of its contents. Multicast mode avoids having to open another socket for the response, but all of the responses will create traffic in each application's socket.
