DRAFT
● 1.1 Mbps for 720p/60fps
● 1.7 Mbps for 1080p/30fps
● For content (that is, PC input) add ~1.0 Mbps (1040 and 1050 models only)
● For wideband audio add 80 kbps (includes overhead)
Quality of Service
Quality of Service (QOS) is the ability to provide different priority to different users and voice or
data flows or to guarantee a certain level of performance to a data flow. It is not widely used for
audio-only networks but is critical as multimedia is more widely deployed.
You can assign a QoS tag from the video endpoint itself or from a central control, such as
Communication Manager. If no QoS tag is assigned, the network uses its best effort to get the
video to its destination.
User classification
Users can be classified as either normal or priority users with most users falling into the normal
category. If you want some users to be priority users, then
● Set up a priority class of service (CoS) group.
● Assign priority IP video to that priority CoS group.
● When you set up an endpoint for a priority user, assign the user to that priority CoS group.
● Assign a higher maximum call bit rate for priority IP multimedia.
For users of H.323 endpoints, you can set up separate bandwidth pool within a network region
for priority video users.
Bandwidth management
Bandwidth management is partitioning your enterprises total bandwidth to ensure that you have
enough bandwidth to support video. Partitioning total bandwidth generally starts by separating
calls first by a logical location, generally geographical, second by type of call: audio-only or
multimedia, and third, for H.323 endpoints, by type of user: normal or priority. Keep in mind that
these bandwidth allocations are for voice traffic only and are separate from the data traffic.
To partition bandwidth by geographical location, you use two methods: Network Regions for
H.323 endpoints and Locations for SIP endpoints. Network Regions are administered through
Communication Manager, and Locations are administered through System Manager.
