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 113 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.
