4.4.4.6 IP DSCP Priority Qos

Differentiated Services (DiffServ) is a class of service(CoS) model that enhances best-effort

Internet services by differentiating traffic by users, service requirements and other criteria.

Packet are specifically marked, allowing network nodes to provide different levels of service,

as appropriate for video playback, voice calls or other delay-sensitive applications, via priority

queuing or bandwidth allocation.

The DSCP value used to identify 64 levels of service determines the forwarding behavior that

each packet gets across the DiffServ network. Based on the marking rule different kinds of

traffic can be marked for different priorities of forwarding. Resources can then be allocated

according to the DSCP values and the configured policies.

Set up queue index (0, 1, 2 or 3) on each DSCP:

Command: setup qos ipDscpPri <0~63> <0~3>
