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.

Abstract: A routing Cable Modem Termination System (CMTS) configured to enable Point-to-Point Protocol over Ethernet (PPPoE). The routing CMTS may bridge Ethernet frames related to a PPPoE connection from a first network to a second network. Bridging Ethernet frames allows terminals in different networks to establish a PPPoE connection. A routing CMTS may also collect state information regarding PPPoE connections. The routing CMTS may use the state information to only bridge Ethernet frames related to valid PPPoE connections. It may act as a firewall to prevent spoofing attacks.
