Chapter 16 Bandwidth Management

16.5.1 Priority Levels

Traffic with a higher priority gets through faster while traffic with a lower priority is dropped if the network is congested.

The following describes the priorities that you can apply to traffic that the NBG- 417N forwards out through an interface.

High - Typically used for voice traffic or video that is especially sensitive to jitter (jitter is the variations in delay).

Low - This is typically used for all other traffic that are not time-sensitive.
