In the QoS framework, the concept of class of service is introduced to QoS mapping. After
QoS is enabled, the ZXV10 W811N can completely control the data packets in both ingress
and egress directions. For the data packets in the ingress direction, the domain mapping (ToS
and priority) needs to be converted to queue. For the data packets in the egress direction, the
queue needs to be converted to domain mapping.

Parameter
Description
Enable QoS
Enables or disables the QoS function.
Total Upstream Bandwidth
Indicates the total upstream bandwidth.
Enable Queue
Management
Enables or disables the function of queue management.
By default, this function is disabled.
Scheduler Algorithm
The available options are
SP
,
DWRR
, and
SP_DWRR
.
SP
: The packets in the queue are transmitted by strictly
following the priority sequence in descending order. When
the queue of high priority is empty, the packets in the
queue of low priority are transmitted.
DWRR
: Indicates dynamic weighted round-robin. In this
mode, scheduling is implemented among queues in turn
to ensure each queue can obtain a period of service time.
Enable DSCP Re-marking
Enables or disables the function of DSCP re-marking. By
default, this function is disabled.
Enable 802.1p Re-marking
Enables or disables the function of 802.1p priority
re-marking. By default, this function is disabled.
