Traffic Mirroring

Traffic mirroring is used to copy a service flow matching the ACL
rule to the CPU or specific port to analyze and monitor packets
during network fault diagnosis.

Traffic Statistics

Traffic statistics is used to sum up packets of the specific service
flow. This is to understand the actual condition of the network
and reasonably allocate network resources. The main content of
traffic statistics contains the number of packets received from the
incoming direction of the port.
Queue-Based Bandwidth Upper and
Lower Threshold
Due to limited queue buffer resources, when network congestion
occurs, multiple packets will compete to use limited resources.
After configuring upper and lower threshold on outgoing inter-
face and when multiple flows compete for limited resources, a cos
queue flow can obtain a bandwidth which will not be less than
bandwidth lower threshold or more than bandwidth upper thresh-
old. In this way, no flow can occupy the entire bandwidth which
makes the other flows fail to obtain any bandwidth.

HQoS

Hierarchical QoS (HQoS) is to schedule and control traffic by con-
figuring network topology extracted from actual network, which
ensures quality of network.
HQoS has the following functions.
HQoS Functions
�
Change the CoS queue of the packet and change the 802.1p
value.
Change the CoS queue of the packet and do not change the
802.1p value.
Change the DSCP value of the packet.
Change the discard priority of the packet.
Supporting hierarchical scheduling
The most obvious characteristic of HQoS is hierarchical sched-
uling. It is used to simulate complex networks.
