| 20090296737 | METHOD AND SYSTEM FOR CONNECTING TWO NODES OVER MULTIPLE COMMUNICATION LINKS - A communications system to inverse multiplex media communication traffic from a high-speed communication link into a plurality of low-speed communication links, wherein each low-speed link can use a different physical line, having different speeds, and wherein the communication over each link can comply with different communication protocols and can be connected on different networks, and then combined the media communication traffic at the other end. The system may include a transmitting inverse multiplexer and a receiving multiplexer. The transmitting inverse multiplexer can be connected to an egress of one of the nodes as the high-speed communication link. The receiving multiplexer can be connected to ingress of a second node as the other side of the high-speed communication link. The transmitting inverse multiplexer and the receiving multiplexer can communicate over a plurality of communication links. Each communication link can be connected to a different network using a different physical line. | 12-03-2009 |
| 20100122141 | METHOD AND SYSTEM FOR SENSING AVAILABLE BANDWIDTH OVER A BEST EFFORT CONNECTION - A bandwidth sensing system operates to sense the existence of additional bandwidth available for transmitting data over a best effort communication. The operations include receiving an original block of data from a transmitting node and calculating error correction data based on the original block of data. The original block of data and the error correction data is then transmitted toward a receiving node. The data may be simply appended or, the entire block may be modified during the error correction data process. When the original block of data and error correction data is received at the receiving end associated with the receiving node, the data is analyzed to determine if any errors occurred in the transmission. If so, the error correction data is used to maintain the integrity of the transmitted data by restoring the original block. However, if no errors are detected, because the error correction data inherently requires the transmission of additional data, the receiving end can conclude that additional bandwidth is available over the channel. Thus, the transmitting node can be notified of the available bandwidth so that additional bandwidth can be utilized on subsequent transmissions. | 05-13-2010 |
| 20110066915 | ADAPTING BIT ERROR RATE TO A TARGET QUALITY OF SERVICE - Communication frames transmitted over a communication network may have different QoS requirements for each communication session. The required BER for different types of communication session is selected based at least in part on the required QoS for that communication session. When frames are received, the QoS level associated with the frame is determined Based at least in part on the QoS level, the frames are routed toward the destination over a path that provides BER protection commensurate with the required QoS. Prior to transmission to the destination, the processed frames are multiplexed together into a single stream of segment. On the receiving side, the stream of segments is divided in accordance with the QoS level associated with the segments and the segments are routed over a path that is selected, at least in part, on the QoS level. Over this selected path, the original frames are restored and then provided to the destination node. | 03-17-2011 |
