3.6.5 Congestion Avoidance
The network equipment has limited processing capability and buffering capability. The
packets exceed equipment processing capability will cause congestion. Simply dropping
these packets will cause ‘global synchronization’. ZXR10 ZSR V2 adopts RED/WRED to
avoid congestion and improve network quality. WRED can sense the service IP priority,
DSCP and MPLS EXP. It can set different early dropping strategy for packets with
different priorities so as to provide differentiated dropping features for different services.
3.6.6 MPLS QoS
ZXR10 ZSR V2 supports MPLS QoS based on Diff-Serv model. MPLS QoS implements
mapping of priority between MPLS, IP and Ethernet packets. It also differentiate data
flow of different services based on the value of EXP in the tag, so as to realize different
services, guarantee the QoS of voice and video services. ZXR10 ZSR V2 supports
operator MPLS QoS service channels of three standards:
 Uniform Tunnel
 Pipe Tunnel
 Short Pipe Tunnel
ZXR10 ZSR V2 combines MPLS-TE and Diff-Serv to offer IP/MPLS core network with
service identifying capability. Based on this it establishes tunnel to guarantee the
bandwidth of service with high priority. ZXR10 ZSR V2 supports QoS scheduling inside
MPLS VPN. It can implement Diff-Serv scheduling inside VPN and guarantee the key
VPN services are forwarded with priority.
ZXR10 ZSR V2 supports user service-based PW differentiation, and mapping of service
PW to the corresponding MPLS tunnel to realize E2E QoS based on service. It’s easy to
deploy with the bandwidth management plannable. It provides operation guarantee for
service differentiation management and service.
