● Quality of Service (QoS) monitoring,
● transferring of information about session participants,
● regular distribution of control packets containing quality information to all session partici-
pants.
TCP
TCP (Transmission Control Protocol) provides a connection-oriented mode for data transmis-
sion. TCP guarantees a sequenced, error-free, flow-controlled transmission of data packets.
However, this can delay data transfer and reduce throughput. H.323 uses the end-to-end ser-
vices of TCP for the H.245 control channel, data channels and the call control channel.
UDP
The UDP (User Datagram Protocol) provides a connectionless transmission mode that prom-
ises nothing more than a “best effort” delivery. Only a minimum of control information is trans-
ferred with UDP. H.323 uses UDP for audio, video and the RAS channel (see RFC 768).
