8. Quality of Service (QoS)
Diffserv defines a field in IP packet headers referred to as DSCP. Hosts or routers passing
traffic to a Diffserv-enabled network will typically mark each transmitted packet with an
appropriate DSCP. The DSCP markings are used by Diffserv network routers to
appropriately classify packets and to apply particular queue handling or scheduling
behavior.
The gateway provides a table of predefined DSCP values, which are mapped to 802.1p
priority marking method. You can edit or delete any of the existing DSCP setting, as well as
add new entries.
