Abstract: Systems and methods are described for effectively managing the quality of service provided to subscribers in a shared network on a per-application, per-user basis. A system QoS proxy, sitting on a subscriber's computing device or on a web content server, captures network calls made by an application for a subscriber and uses locally stored quality profiles to determine if a request for high-quality communications should be made. If so, the QoS proxy requests QoS from a central application manager, which dedicates a high-quality communications session to the subscriber's application, and causes the subscriber to be billed appropriately.
