U
UDP
User Datagram Protocol. A connectionless protocol that does not have any guarantee of delivery. The major
benefit of UDP is the connection uses much less bandwidth than TCP.
unicast
Sending each user their own copy of a video (or other data) stream. As opposed
to Multicast, where one copy is sent and whoever wants it listens to that
copy. It is the most commonly used method for videoconferencing and video
on demand today. Multicast, which is much more efficient, is slowly gaining
ground, but requires Internet Service Providers to support it.
