QOS
(IN
ROUTER
AND
WISP
MODE)
Quality
of
service
(QoS)
is
the
overall
performance
of
computer
network,
particularly
the
performance
seen
by
the
users
of
the
network.
Quality
of
service
is
particularly
important
for
the
transport
of
traffic
with
special
requirements.
In
particular,
video
or
voice
over
IP
applications.
QoS,
which
is
also
known
as
traffic
shaping,
assigns
a
priority
to
each
device
(or
service)
operating
on
the
network
and
controls
the
amount
of
bandwidth
each
is
allowed
to
consume
based
on
its
role.
Without
this
kind
of
control,
each
device
would
use
up
as
much
bandwidth
as
possible.
Proper
Quality
of
Service
is
advisable
if
you
use
your
network
to
play
online
games,
make
VoIP
such
as
Skype
calls,
watch
YouTube
or
stream
video
for
example
to
Twitch.
Configuring
QoS
can
be
quite
complex,
and
the
Intellinet
CPE
Access
Point
allows
a
very
detailed
control
over
the
data
and
how
it
is
prioritized
indeed.
Setting
this
up
incorrectly
can
cause
more
harm
than
good,
and
because
of
that
it
is
highly
recommended
that
you
are
familiar
with
QoS
and
its
related
terms
such
as
DSCP,
etc.
This
is
where
things
get
trickier.
Upstream
describes
all
data
traffic
that
you
send
from
your
local
network
to
the
Internet,
for
instance,
traffic
from
your
PC
to
your
Twitch
or
YouTube
live
broadcast.
Downstream
is
the
opposite.
If
you
watch
a
video
on
YouTube,
data
is
sent
from
the
Internet
to
your
local
network,
and
that
is
considered
download
or
downstream.
Mode
‐
Equity:
The
access
point
will
try
its
best
to
distribute
the
available
bandwidth
evenly
and
fairly
between
the
available
network
clients.
No
one
client
will
be
especially
limited
or
given
any
special
treatment
over
the
other.
This
mode
is
not
as
effective
as
Priority,
Limit
or
Assure.
Mode
‐
Priority:
When
selected,
you
can
assign
network
clients
one
of
three
possible
priorities.
This
allows
you
to
quickly
categorize
network
clients,
for
example
guests,
normal
users
and
power
users.
The
example
on
the
right
shows
an
example
on
how
to
create
a
rule
for
10
computers
(IP
192.168.2.50
–
192.168.2.59)
which
have
high
priority
Level
with
DSCP
set
to
AF11.
You
can
identify
computers
based
on
their
IP
addresses
(as
shown),
or
based
on
their
MAC
address.
Furthermore,
you
can
limit
the
rule
to
only
affect
traffic
for
a
certain
Protocol
(TCP
or
UDP)
and
Port
.
