5.2.13 QoS
The QoS interface is shown as below. See Figure 5-27.
Qos (Quality of Service) is network security mechanism. It is a technology to fix the network delay and
jam problem and etc. For the network service, the quality of service includes the transmission bandwidth,
delay, the packet loss and etc. We can guarantee the transmission bandwidth, lower the delay, reduce
the loss of the data packet and anti-dither to enhance the quality.
We can set the DSCP (Differentiated Services Code Point) of the IP to distinguish the data packet so
that the router or the hub can provide different services for various data packets. It can select the
different queues according to the priority of the packets and select the bandwidth of the each queue. It
can also discard at the different ratio when the broad bandwidth is jam.
