Description
Dscp remarking mode
Lets you select the DSCP remarking mode that the Gateway is to use. Choices are:
•
Map frame priority to AF code points = select this option for Quality of Service configurations that use
assured forwarding (AF) code points to mark packets. AF guarantees a certain amount of bandwidth to
an AF class and allows access to extra bandwidth, if available. (
default
)
•
Map frame priority to CS code points = select this option for Quality of Service configurations that use
class selector (CS) code points to mark packets. CS provides code points that can be used for
backward compatibility with IP Precedence. IP Precedence is a legacy technology that the Gateway
supports for backwards compatibility.
Request a remarking action when DSCP equals one of the following CPs
Expedited Forwarding
Code Point
Expedited forwarding provides a low-loss, low-latency, low-jitter, and assured bandwidth service.
Applications such as VoIP, video, and other time sensitive applications require a robust network treatment
like expedited forwarding. When checked, the Gateway requests a remarking action if DSCP equals an
expedited forwarding code point. By default, this option is not checked.
