Streaming Transport

Streaming Transport
There is one other option. Multicast traffic may not be acknowledged, but that is no reason for
us to abandon all efforts to deliver the data in the sequence in which it was transmitted.
Real-Time Protocol (RTP) is one option to assist us here. RTP runs over UDP and provides
both sequence information and a timestamp for each datagram. Although this in itself doesn’t
provide any service guarantees, it does mean that the receiver can make adjustments by changing
the order of packet arrival to restore simple out-of-sequence deliveries, and packets arriving
too late for insertion into the stream decoders can be ignored.
