9.2.3 Setting up Multicast from Publish Stream
A multicast RTP stream provides a one-to-many broadcasting framework. In a
multicast RTP configuration, the Lecture Recorder x2 sends a packet only once to a
router that supports multicasting. This router then distributes the packets to all
intended viewer nodes using a multicast protocol.
A multicast address is associated with a group of interested receivers. In IPv4,
addresses 224.0.0.0 through 239.255.255.255 (the former Class D addresses) are
designated as multicast addresses.
