  • Multimedia data flow dropping with notification
    Patent number: 8077606
    Abstract: A method and system for correcting a congestion condition within a network, the method including notifying the sender and receiver of a multimedia data flow or flows that the multimedia data flows have been dropped due to the presence of the congestion condition. The method including the steps of determining at least one multimedia data flow that will be dropped to relieve the congestion condition; constructing notification messages for the source and destination of the dropped flows; and sending the notification message to the source and destination of the dropped multimedia data flows.

  • Multimedia data flow dropping
    Patent number: 8045454
    Abstract: The present invention introduces a congestion control mechanism for constant bit rate (CBR) multimedia data flows in cable operator IP networks. A flow drop method within a congestion control unit of the present invention chooses a subset of multimedia data flows to drop, in whole, to alleviate a congestion condition. After the congestion condition is detected and the congestion control unit begins dropping multimedia data flows, the remaining multimedia data flows are no longer degraded for the end user, as compared to conventional congestion management systems.
