10.7 IP QoS via Differentiated Services (DiffServ)
DiffServ is an architecture providing different types or levels of service for IP traffic. DiffServ
(according to RFC 2474) offers the capability to prioritize certain traffic types depending on
their priority, thereby, accomplishing a higher-level QoS at the expense of other traffic
types. By prioritizing packets, DiffServ routers can minimize transmission delays for time-
sensitive packets such as VoIP packets.
The device can be configured to set a different DiffServ value to IP packets according to
their class-of-service: Network, Premium Media, Premium Control, Gold, and Bronze. The
DiffServ parameters are described in ''Networking Parameters'' on page 213.
For the map
ping of an application to its class-of-service, refer to IEEE 802.1p/Q (VLANs
and Priority).
