A. Installing QOS support is easy, the next task is to administer QOS, telling which users can reserve how much bandwidth etc.
Policies are defined using the QoS Admission Control MMC snap-in (Start – Programs – Administrative Tools – QoS Admission Control) and there are two areas policies can be defined for, the entire enterprise or for individual subnets and these subnets are defined using the Active Directory Sites and Services MMC snap-in.
Within the various Enterprise or subnet configurations are two types of policies, Authenticated and Un-Authenticated users. An authenticated user is any user in a trusted domain and is requesting QoS from a Windows 2000 client; the later is anyone not fitting the former description. It is possible to add policies for a specific user or Organizational Unit also.
The actual configuration of the QoS policy is the same for Enterprise or a subnet and so we will just look at the configuration of a single policy.
- Start the QoS Admission Control MMC
- Select the ‘Enterprise Settings’ branch
- Right click on ‘Any Authenticated User’ and select Properties
- Under the General property sheet you will notice ‘Any authenticated user’ is selected for the Identity. The direction is send and receive and you will see the Service level is All, other options for the service level are controller load, guaranteed service and disabled.
- Selecting the ‘Flow limits’ tab allows the data rate (by default 500 Kbits/sec), the peak data rate and the duration to be set for each data flow
Click here to view image - The final tab, ‘Aggregate limits’ sets limits for ALL data flows combined and includes total combined data rate, combined peak data rate and number of simultaneous data flows
