insertion,
when

5.3
QoS
&
BWM
The
total
amount
of
data
traffic
increases
nowadays
as
the
higher
demand
of
mobile
applications,
like
Game
/
Chat
/
VoIP
/
P2P
/
Video
/
Web
access.
In
order
to
pose
new
requirements
for
data
transport,
e.g.
low
latency,
low
data
loss,
the
entire
network
must
ensure
them
via
a
connection
service
guarantee.
The
main
goal
of
QoS
&
BWM
(Quality
of
Service
and
Bandwidth
Management)
is
prioritizing
incoming
data,
and
preventing
data
loss
due
to
factors
such
as
jitter,
delay
and
dropping.
Another
important
aspect
of
QoS
is
ensuring
that
prioritizing
one
data
flow
doesn’t
interfere
with
other
data
flows.
So,
QoS
helps
to
prioritize
data
as
it
enters
your
router.
By
attaching
special
identification
marks
or
headers
to
incoming
packets,
QoS
determines
which
queue
the
packets
enter,
based
on
priority.
This
is
useful
when
there
are
certain
types
of
data
you
want
to
give
higher
priority
to,
such
as
voice
packets
given
higher
priority
than
Web
data
packets.
To
utilize
your
network
throughput
completely,
administrator
must
define
bandwidth
control
rules
carefully
to
balance
the
utilization
of
network
bandwidth
for
all
users
to
access.
It
is
indeed
required
that
an
access
gateway
satisfies
the
requirements
of
latency
‐
critical
applications,
minimum
access
right
guarantee,
fair
bandwidth
usage
for
same
subscribed
condition
and
flexible
bandwidth
management.
AMIT
Security
Gateway
provides
a
Rule
‐
based
QoS
to
carry
out
the
requirements.
5.3.1
Configuration
AMIT
gateways
adopt
rule
‐
based
approach
to
define
the
QoS
&
BWM
function.
Before
the
function
works
as
expected,
some
system
resources
must
be
allocated
correctly
in
"Configuration"
page
as
below.
In
"Configuration"
page,
there
are
some
configuration
windows
for
QoS
&
BWM
function.
