Policy-based Quality of Service (QoS)
Applies To: Windows Server 2008 R2
Quality of Service (QoS) in Windows Server 2008 and Windows Vista helps to reduce network congestion and optimize bandwidth by providing centralized management of traffic sent by network hosts.
The following is a list of all aspects that are part of this managed entity:
Advanced Quality of Service (QoS) settings provide additional controls for IT administrators to manage computer network use and DSCP markings. Advanced QoS settings apply only at the computer level, whereas QoS policies can be applied at both the computer and user levels.
Quality of Service (QoS) policies are applied to a user or computer account by using Group Policy. The QoS policies are applied to a Group Policy object (GPO), which is then linked to an Active Directory container, such as a domain, site, or organizational unit (OU), that contains the user or computer account.
