In
some cases, the network operator may want to use the BreezeMAX system for
markin
g QoS classes, in order to provide network-wide QoS and enable the
upstream network to handle the traffic accordingly. Within the BreezeMAX
system, frames can be classified to QoS classes using Priority Classifiers, base
on either a DSCP header or 802,1p tag. This applies only in cases where an
external networking device marks the applicable fields. BreezeMax also enables
marking data transmitted to the backbone network with either DSCP or 802.1p
values, where the marking is done per Service Profile. This marking overrides
