Figure 6-17 Detailed Graph of a CTS-1000 Video Stream (Version 1.6)
As can be seen from Figure 6-17, TelePresence video packets average slightly under 1100 bytes in size.
Each video frame consists of approximately 16 packets, spaced from 1–3 msec apart, spread across the
33 msec frame interval. Based on this analysis, a UDP jitter IP SLA operation consisting of 1060 byte
packets with a interval of 2 msec between packets, sent with a ToS value equivalent to CS4 traffic, would
simulate the size and packet rate of a TelePresence video stream. The overall data rate would be
approximately 1060 bytes/packet * 500 packets/sec * 8 bits/byte = 4.24 Mbps.
Figure 6-18 shows a close-up of the graph from a data capture of a single audio stream from a
TelePresence CTS-1000 running Cisco TelePresence System version 1.6 software.
