3.2.12.3 MPLS QoS
MPLS QoS is an important part of QoS service deployment. Since DiffServe has good
deployment flexibility and scalability, QoS is usually implemented by DiffServe in
practical MPLS networking solution. ZXR10 5900E supports MPLS QoS based on
DiffServe model. Traditional IP QoS decides the service level based on IP priority or
DSCP to implement differentiated service. MPLS QoS differentiates data flow of different
services based on EXP value, and implements mapping between MPLS EXP and IP as
well as Ethernet, so as to realize differentiated services and guarantee quality of voice
and video services. At MPLS Ingress PE, the IP priority of the packets or VLAN priority
takes mapping of duplication in CoS doman of the label. The classified traffic is
monitored, shaped and scheduled. Service level is differentiated based on CoS field of
MPLS label to guarantee the network service quality.

3.2.13 Port Mirroring

Port mirroring is actually to replicate services with matched ACL rule to CPU or
designated port for message analysis and monitoring. Normally it is used for network
failure diagnosis.
