Class of Service and DSCP Values
Each Class of Service is associated with the specific value of the DSCP
field. The table lists the values recommended in compliance with RFC 2597
[10] and RFC 2598[11].
Default — Non-guaranteed delivery. The network resources which remain
idle during the transmission of traffic of other classes are allocated for the
traffic of this Class of Service.
AF — Assured Forwarding. It is used for delivering traffic of the most TCP
applications using four independent AF classes. Within each class IP
packets can be assigned one of three data packet discard disciplines.
