16.1.3 Example using QoS to Ensure Bandwidth for Critical Traffic
This example assumes two PC workstations, each on a different VLAN and subnet. Client
1 is running a very important and sensitive application that requires a minimum of 2 Mbits
of network bandwidth for proper operation. Based on the mechanisms described in this
chapter, a policy is configured to ensure the client obtains the required bandwidth.
