20100278043 | METHOD AND SYSTEM FOR IDENTIFYING DEGRADATION OF A MEDIA SERVICE - A method and device for identifying degradation in service quality for a wireless media service. The wireless media service has a known expected packet generation rate, which may be determined by the device based upon the codec and payload size selected on initiating the media service. At a receiving device, the packets actually received by the device from the other termination point are counted over a time period, and this number is compared with the number of packets that were expected based upon the known packet generation rate. From this comparison a packet loss rate may be determined. If the packet loss rate exceeds a threshold level, then the device may issue a user alert, terminate the service, or take other action. The threshold level may be established based upon a packet loss rate corresponding to a significant degree of service quality degradation. | 11-04-2010 |

20140269293 | CABLE MODEM TERMINATION SYSTEM CONTROL OF CABLE MODEM QUEUE LENGTH - Buffer bloat continues to cause latency problems for all kinds of network traffic, e.g., internet protocol traffic. Implementing network based control of packet upstream packet discards enables a scheduler of packets to manage congestion, instead of the network element with bloat. In embodiments, a cable modem termination system may schedule delivery of packets and, after receiving the scheduled packets, discarding packets. The cable modem termination system may determine when to discard a packet based on a detected backlog of data in a cable modem upstream flow queue. For example, a late discard of such packets may be based on information in a schedule request received from the network element. | 09-18-2014 |
