5.2 QoS
QoS (Quality of Service) functions to provide different quality of service for various network applications and requirements
and optimize the bandwidth resource distribution so as to provide a network service experience of a better quality.
QoS
This switch classifies the ingress packets, maps the packets to different priority queues and then forwards the packets
according to specified scheduling algorithms to implement QoS function.
Traffic classification: Identifies packets conforming to certain characters according to certain rules.
Map: The user can map the ingress packets to different priority queues based on the priority modes. This switch
implements priority modes based on port.
Queue scheduling algorithm: When the network is congested, the problem that many packets compete for resources must
be solved, usually in the way of queue scheduling. The switch supports three schedule modes: SP, WFQ,WRR
5.2.1 Priority selection Setting
This switch implements three priority modes based on port, on 802.1P and on DSCP. By default, it is based on port, 802.1P
and DSCP priority modes.
