QoS Priority Configuration:
The Residential Gateway supports QoS of the egress traffic.
QoS of the Residential Gateway provides four queues for packet transmission
– Queue 0, Queue
1, Queue 2 and Queue 3. Queues are used to store packets before the packets are transmitted.
You can designate a queue to store packets if they meet a pre-determined condition of the QoS
rule. Then, the queues will follow the priority order or the ratio of transmission rates to transmit the
packets. Below is a description of configuration parameters in this section.
Priority Modes
—
The Residential Gateway provides three QoS priority modes
—
Port
,
DSCP
, and
802.1p
. Select one of them in the pull-down menu to decide how you want to
map the packets to the queues. Or select
Disable
to deactivate the QoS feature.
Port
—
Select this mode to bind every port of the Residential Gateway with a queue. And
packets will be assigned to different queues according to the ports from which
they leave the Residential Gateway. The Residential Gateway will follow the
priority orders or the ratio of the transmission rates of the queues which store the
packets to transmit packets.
802.1p
—
Select this mode to bind the 802.1p values of the packets with the designated
queues. And packets will be assigned to different queues according to their
802.1p values. The Residential Gateway will follow the priority orders or the ratio
of the transmission rates of the queues which store the packets to transmit
packets.
DSCP
—
Select this mode to bind the DSCP values of the packets with the designated
queues. And packets will be assigned to different queues according to their
DSCP values. The Residential Gateway will follow the priority orders or the ratio
of the transmission rates of the queues which store the packets to transmit
packets.
Queue Mode
—
If you select
strict
, the Residential Gateway will follow the priority orders
of the queues to transmit packets. It will not start to transmit packets in a queue until all
packets in the queues which have higher priorities are transmitted. And the priorities of
the four queues from high to low are Queue 3, Queue 2, Queue 1 and Queue 0. If you
