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.
present the overall requirements for each service and the requirements for the user
groups of each service respectively.
