摘要： A peer-to-peer forwarding node supports the operation of a teleconference across a telecommunications network. The telecommunications network comprises a plurality of nodes including one or more source locations and one or more remote locations. The teleconference includes teleconference participants at each of the source and remote locations. The peer-to-peer forwarding node is located at a given one of the plurality of nodes. The peer-to-peer forwarding node comprises a receiver and a transmitter. The receiver receives a request from a telecommunications controller to provide peer-to-peer forwarding of a media signal to be received from a first one of the source locations to a first one of the remote locations and which further receives the media signal from the first one of said source locations. The transmitter forwards the media signal from the first one of the source locations to the first one of the remote locations.

摘要： A method processes a data packet in a first sequence of disjoint original segments of the same length. The method includes modifying a first of the original segments of the first sequence by modifying one or more symbols therein. A start of the data packet is located in the first of the original segments and is positioned after a first digital data symbol therein. The method also includes modifying a last of the original segments of the first sequence by modifying one or more digital data symbols therein. An end of the data packet is located in the last of the original segments and is located before the last digital data symbol therein. The method also includes determining a remainder sequence by effectively performing a polynomial division on a second sequence of disjoint segments that are derived from the first sequence. Each segment of the second sequence corresponds to and is derived from one of the original segments of the first sequence. The segments of the second sequence have the length of the original segments of the first sequence. A first of the derived segments of the second sequence is the modified first of the original segments. A last of the derived segments of the second sequence is derived from the modified last of the original segments.

摘要： A dual transmission network may use a hybrid architecture where two types of links, such as wireless and fixed, function in a parallel manner for communicating control information and data. In at least one example embodiment, an apparatus includes at least two local transceivers and a controller. The controller is connected to control the two local transceivers and configured to establish parallel first and second communication links with a remote terminal via at least one of the local transceivers. The first communication link uses a first physical layer communication protocol and the second communication link uses a second physical layer communication protocol. The second physical layer communication protocol may be different from the first physical layer communication protocol or the first and second transceivers may be configured to operate on different frequencies.

摘要： A teleconferencing system in which a teleconference controller advantageously uses information relating to the network topology layout of remote nodes which are to participate in a teleconference, and then advantageously directs the transmission of video and/or audio streams from a source node to an identified subset of the remote nodes based on the capabilities of the nodes and the network links. These nodes which initially receive the video and/or audio streams then advantageously forward the streams in turn to other nodes in their vicinity using peer-to-peer network connectivity techniques. The identification of the subset of nodes which serve as peer-to-peer forwarding nodes may be based on node activity, node service capacity, the impact on network links between the node and the requester, the distance and/or latency between the node and the requester, and the ability of the node to meet requests including video transcoding requests.

摘要： A method is provided for use in a mobile communication terminal configured to support a plurality of applications, wherein each application is executed by performing one or more tasks. The method includes, in response to a scheduling request from an application, obtaining an indication of power supply condition at a requested run-time of at least one of the tasks. The method further includes obtaining a prediction of a rate of energy usage by the task at the requested run-time, and making a scheduling decision for the task. The scheduling decision comprises making a selection from a group of two or more alternative dispositions for the task. The selection is made according to a criterion that relates the run-tune power-supply condition to the predicted rate of energy usage by the task.

摘要： In a passive optical network, an upstream transmission rate from an ONT to an OLT can be optimized by matching a transmission scheme for a channel to the upstream transmission characteristics of the channel. An FEC coding can be made channel dependent so that channels with low error rates can use minimal protection, and therefore minimal overhead, while channels with high input bit error rates can use the level of FEC coding required to produce a desired output bit error rate.
