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.

Claims

12. The computer-readable medium of claim 7, wherein the request for a high-quality network connection communications session comprises a TOS/DS mark for designating the priority of communications packets in the session.

13. A method for establishing a high-quality network connection communications session between a software application running on a subscriber computer and a network service provider, the method comprising:
