Function name:

QoS

Function description:

This page allows users to configure settings for QoS.

Parameter description:

Disable

Disable the QoS function for LAN ports.

802.1p CoS

Apply 802.1p CoS for each LAN port.

Port-based

QoS settings would apply to specified LAN port only.

Scheduler Method

WFQ: Weighted fair queueing（WFQ）is an algorithm for

data packet scheduling. Such mechanism can specify, for

each flow, which fraction of the capacity will be given.

Strict Priority: Strict Priority (SP) can ensure service for

high-priority traffic. The software assigns the maximum

weights to each queue, to cause the queuing mechanism

to serve as many packets in one queue as possible before

moving to a lower queue. This method biases the queuing

mechanism to favor the higher queues over the lower

queues.

For example, strict queuing processes as many packets as

possible in qosp3 before processing any packets in qosp2,

then processes as many packets as possible in qosp2

before processing any packets in qosp1, and so on.

Port

The sequence of packets passing through LAN port(s)

will be processed according to the queue setting (listed

below) configured in this page.

 Low Priority Queue

 Normal Priority Queue

 Medium Priority Queue

 High Priority Queue

In which, packets transmitted via LAN Port with High
