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 84 assign the
packets a priority level of 4 and limit the bandwidth to 5 Mbps. 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.
