Overview
QoS
is
a
technique
for
prioritization
of
network
traffic
packets
during
congestion.
RADWIN
5000
sectors
support
two
classification
criteria,
VLAN
based
or
Diffserv
based.
You
may
choose
which
of
them
to
use.
Based
upon
the
classification
criterion
chosen,
received
packets
will
be
mapped
into
one
of
four
quality
groups:
Real
time,
Near
real
time,
Controlled
load
and
Best
effort.
You
may
partition
the
total
link
capacity
across
the
four
Quality
queues.
The
default
weights
as
percentages
are
shown
in
