2.6.3 Example for Configuring Hierarchical Traffic Policing on the
S3700HI
Hierarchical traffic policing sets different CAR parameters for different users and services to
provide differentiated broadband services.
Networking Requirements
As shown in
the provincial center and city B is implemented by leasing the carrier network. The carrier
allocates 2 Mbit/s bandwidth for each city. The provincial center is connected to the carrier
network through the Switch and traffic needs to be controlled on the Switch to ensure that:

The rate limit of the traffic sent from the provincial center to each city is 2 Mbit/s.
The Switch processes voice, video, and data services based on priorities. It sends traffic
with higher priorities first and allocates certain bandwidth to traffic with lower priorities.
With bandwidth guarantee, bandwidth is allocated randomly.
