    摘要: A circuit for eliminating illegal data sequences from a data stream is disclosed. The circuit examines a portion of an input data stream. The previously received data sequence is then examined. If the previously received data matches an illegal sequence, the stored data is altered. The stored data is then outputted to form an output data sequence.

    摘要: Systems and methods of automatically determining a set of route targets is provided. The method includes receiving network topology data specifying configuration of a network. The method also includes automatically converting the network topology data into route targets to be assigned to virtual routing and forwarding elements. The route targets are grouped into sets and duplicate sets of route targets are removed based on the route targets between duplicate sets of route targets identified as being the same. The method further includes generating a data record including information related to the set of route targets.

    摘要: A method of providing video content includes receiving a channel change data packet from a set-top box device at a subscriber premise via a packet-based video distribution network. The channel change data packet includes data indicating a requested channel and a channel change index value. The method also includes reading the channel change data packet to identify the channel change index value. The channel change index value indicates an available bandwidth at the subscriber premise to receive video content of the requested channel via the packet-based video distribution network. The method also includes allocating an overhead bandwidth to the set-top box device based on the channel change index value.

    摘要: A method of delivering video content includes receiving a request for a video stream at a network device of a video distribution network. The request is received via a network link associated with a link aggregation group. The method includes determining a current real-time traffic load at each of a plurality of physical interfaces associated with the link aggregation group at the network device. Further, the method includes identifying an interface having a lowest traffic load of the plurality of physical interfaces. The lowest traffic load is lower than a pre-defined threshold. The method includes determining a total traffic load for the identified interface. The total traffic load includes an estimated traffic load corresponding to the requested video stream and including the lowest traffic load. The method also includes sending the requested video stream via the identified interface when the total traffic load is lower than the pre-defined threshold.
