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.
