Video Applications
Video applications typically require a larger bandwidth than voice
applications. Video applications can be set up to have a high priority and
buffering, depending on the application.
This example creates policies with low latency and jitter for video streams
(for example, net conference calls). The policies in Figure 112 assign the
packets a priority level of 4. The policies also limit the bandwidth for the
video streams to 5 Mbps to illustrate how you can combine a change to
the priority level with bandwidth restriction to further define traffic control.
The node containing the application has the IP address 149.44.44.44.
Policy 17 is assigned to port 1, where the application is located, and Policy
32 is assigned to port 8 where packets destined to the application enter
the switch.
