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
, data exchange between the provincial center and city A, and between
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:
l
The rate limit of the traffic sent from the provincial center to each city is 2 Mbit/s.
l
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.
l
With bandwidth guarantee, bandwidth is allocated randomly.
