4.3.7.3.2 Map DiffServ DSCP and Priority Queue
Differentiated Services (DiffServ) was first described by RFC2474 which redefines the
TOS octet’s first six bits as the Differentiated Services Code Point (DSCP). This field
selects the per-hop behaviour (PHB) how packets are queued at network nodes.
RFC 2475 describes DiffServ methods for scalable differentiated services on the
Internet.
Figure 25 displays the first screen of default parameters that apply if you chose DiffServ
as your QoS type. Figure 26 displays the remainder of the default parameters.
