What Is QoS?
On the SSR, QoS is a set of parameters that let you do the following:
•
Establish a queuing policy on the SSR to prioritize the SSR’s traffic.
•
Associate a precedence with Layer-3/Layer-4 flows. You do so by assigning a
precedence value to each field in those type of flows. The SSR uses the precedence
value assigned to the fields to break ties if packets match more than one flow.

•
Classify Layer-2, Layer-3, and Layer-4 network traffic into one of the following
priorities:
