QCL
QCL
is
an
acronym
for
Q
oS
C
ontrol
L
ist.
It
is
the
list
table
of
QCEs,
containing
QoS
control
entries
that
classify
to
a
specific
QoS
class
on
specific
traffic
objects.
Each
accessible
traffic
object
contains
an
identifier
to
its
QCL.
The
privileges
determine
specific
traffic
object
to
specific
QoS
class.
QL
QL
In
SyncE
this
is
the
Quality
Level
of
a
given
clock
source.
This
is
received
on
a
port
in
a
SSM
indicating
the
quality
of
the
clock
received
in
the
port.
QoS
QoS
is
an
acronym
for
Q
uality
o
f
S
ervice.
It
is
a
method
to
guarantee
a
bandwidth
relationship
between
individual
applications
or
protocols.
A
communications
network
transports
a
multitude
of
applications
and
data,
including
high
‐
quality
video
and
delay
‐
sensitive
data
such
as
real
‐
time
voice.
Networks
must
provide
secure,
predictable,
measurable,
and
sometimes
guaranteed
services.
Achieving
the
required
QoS
becomes
the
secret
to
a
successful
end
‐
to
‐
end
business
solution.
Therefore,
QoS
is
the
set
of
techniques
to
manage
network
resources.
QoS
class
Every
incoming
frame
is
classified
to
a
QoS
class,
which
is
used
throughout
the
device
for
providing
queuing,
scheduling
and
congestion
control
guarantees
to
the
frame
according
to
what
was
configured
for
that
specific
QoS
class.
There
is
a
one
to
one
mapping
between
QoS
class,
queue
and
priority.
A
QoS
class
of
0
(zero)
has
the
lowest
priority.
R
RARP
RARP
is
an
acronym
for
R
everse
A
ddress
R
esolution
P
rotocol.
It
is
a
protocol
that
is
used
to
obtain
an
IP
address
for
a
given
hardware
address,
such
as
an
Ethernet
address.
RARP
is
the
complement
of
ARP.
RADIUS

It
is
a
networking
protocol
that
provides
centralized
access,
authorization
and
accounting
management
for
people
or
computers
to
connect
and
use
a
