Quality of Service
– 108 –
will be allowed to transmit up to 8 packets, after which the next lower
priority queue will be serviced according to it's weighting. This prevents
the head-of-line blocking that can occur with strict priority queuing.
This weight determines the frequency at which each queue will be
polled for service, and subsequently affects the response time for
software applications assigned a specific priority value.

EMARKING
The Differentiated Services Code Point should be set at network
boundaries, or by trusted hosts within those boundaries, to ensure a
consistent service policy for different types of traffic. Services can be
realized by the use of particular packet classification (based on DSCP
remarking), buffer management, and traffic conditioning mechanisms (that
is, traffic shaping as provided by the Rate Limiters described on
page 118
).
In the packet forwarding path, differentiated services are realized by
mapping the codepoint contained in a field in the IP packet header to a
particular forwarding treatment, or per-hop behavior (PHB), at each
network node along its path. Traffic conditioners may include the
primitives of marking, metering, policing and shaping.
