Mission-critical applications
Often,
a
VPN
connection
is
a
mission-critical
application
for
exchanging
data
between
Head
and
Branch
offices.
This
mission-critical
application
must
be
connected
smoothly,
without
any
dropping.
To
ensure
this,
you
should
set
the
priority
to
the
high
level
to
preventing
any
other
applications
from
saturating
the
bandwidth.
Voice applications
Voice
applications
are
latency-sensitive.
Most
VoIP
devices
use
the
SIP
protocol,
which
automatically
assigns
a
port
number.
.
This
means
that
it
is
better
to
use
a
fixed
IP
address
to
catch
VoIP
packets
and
rout
them
as
high
priority
traffic.
The
settings
shown
above
will
help
to
improve
the
quality
of
your
VoIP
service
when
the
link
is
fully
loaded.
Restricted Application
Some
users
will
setup
a
FTP
server
for
downloading
of
their
files
by
means
of
FTP.
The
above
settings
will
help
to
limit
utilization
of
upstream
bandwidth
by
the
FTP
connections.
A
time
schedule
can
be
implemented
to
limit
file
downloads
to
non-busy
times.
Advanced setting by using IP throttling
With
IP
throttling
you
can
specify
more
detail
for
bandwidth
allocation;
even
if
applications
are
located
on
the
same
level.
