TOS/DiffServ (DS) priority function can discriminate the Differentiated Service
Codepoint (DSCP) of the DS field in the IP packet header, and map each Code point to

Type-of-Service (TOS) octet in IPv4. The recommended DiffServ Codepoint is defined
in RFC2597 to classify the traffic into different service classes. The mapping of
Codepoint value of DS-field to egress traffic priorities is shown as follows.
