TOS/DiffServ (DS) priority function can discriminate the Differentiated Service
Code Point (DSCP) of the DS field in the IP packet header, and map each Code
Point to a corresponding egress traffic priority. As per the definition in RFC2474,
the DS field is Type-of-Service (TOS) octet in IPv4. The recommended DiffServ
Code Point is defined in RFC2597 to classify the traffic into different service
classes. The mapping of Code Point value of DS-field to egress traffic priorities is
shown as follows.
