The UDP sender.

In contrast to the other senders the UDP sender is active in the sense that it initiates the network connection according to its list of targets rather than passively waiting for clients to connect. Like DCCP streams, UDP streams are always sent FEC-encoded. The UDP sender is the only sender which supports IP multicasting.
