Abstract
A method and apparatus for policy-based management of quality of service treatments of network data traffic flows by integrating policies with application programs are described. In one embodiment, a quality of service value is selectively associated with a flow of information generated by an application program and directed to a network device. Mappings representing an abstract policy and associating a pre-determined network quality of service with a traffic flow type of the flow of information and with an application program are created and stored in a repository that is accessible by the application program. The mappings are converted into one or more settings of the network device. The policy is enforced at the network device in response to receiving traffic from the application program that matches the traffic flow type. The settings may be Differentiated Services Code Points or may be RSVP+ messages. Policies may be represented by statements stored in a directory schema. Each policy statement is represented by nodes that represent a condition of one of the traffic flows, an operator, an operand, and an action comprising one of the quality of service treatments. The nodes start at a root node having a distinguished name in the directory.
