Which three characteristics of a video stream require the implementation of QoS?
Thanks Jeff, that’s a good way to remember the answer for this question.

The requirements for streaming video, such as IP multicast, executive broadcasts, and real-time training activities, are as follows:
Four to 5 seconds of latency allowable (depending on the video application’s buffering capabilities). No significant jitter requirements.
Two percent packet loss permissible. Bandwidth required depends on the encoding and the rate of the video stream.
Video content distribution such as video on demand being replicated to distributed content engines.
Delay- and jitter-insensitive.
Large file transfers (traffic patterns similar to FTP sessions).
Restrict to distribution to less-busy times of day.
Provision as “less-than-best-effort” data.

Video packets are not small and the bandwidth is not constant
