NOTE:
•
HQoS configuration example I and HQoS configuration example II are both applicable to Ethernet
interfaces and POS interfaces.
• Only HQoS configuration example II is applicable to ATM interfaces, serial interfaces, and MP-group
interfaces.
HQoS configuration example I
QoS-local-ID mode identifies services by QoS-local ID. Traffic accessing a backbone router fall into four
types: VoIP, VoD, VPN, and Internet. You can assign different IP segment to carry different services, and
then perform rate limiting and bandwidth management for each type of service. For a service type, you
can further differentiate its users.
Network requirements
Assume that the rate limit for the outgoing interface is 1000 Mbps.
Table 7 and Table 8 present the overall requirements for each service and the requirements for the user
groups of each service respectively.
