29 - 2 SSR Command Line Interface Reference Manual
Queuing Policies
You can use one of two queuing policies on the SSR:
• strict priority – assures the higher priorities of throughput but at the expense of
lower priorities. For example, during heavy loads, low-priority traffic can be
dropped to preserve throughout of control-priority traffic, and so on.
• weighted fair queuing – distributes priority throughput among the four priorities
(control, high, medium, and low) based on percentages.
The SSR can use only one queuing policy at a time. The policy is used on the entire
SSR. The default queuing policy is strict priority.
