摘要： A set of critical nodes or links is identified on the network through which most of the shortest paths on the network occur. Each node compares their distance to end points on the network with a distance between the end points and each of the distinct critical nodes. Where the distance between the end points and the critical nodes is shorter than the distance between the end points and the node, the node is not on the shortest path and does not install forwarding state. Where the distance between the end points and the critical node is larger than or equal to the distance between the end points and the node, the node may be on the shortest path between the pair of end nodes and installs forwarding state. Installation of forwarding state may cause packet duplication, but determining forwarding state is dramatically simplified. The level of duplication may be reduced by selecting a larger number of critical nodes on the network.

摘要： Disclosed is a queue based multi-level Active Queue Management with drop precedence differentiation method and apparatus which uses queue size information for congestion control. The method provides for a lower complexity in parameter configuration and greater ease of configuration over a wide range of network conditions. A key advantage is a greater ability to maintain stabilized network queues, thereby minimizing the occurrences of queue overflows and underflows, and providing high system utilization.

摘要： Where a common network clock is available at both a TDM receiver and a TDM transmitter which communicate via a packet network, differential clock recovery can be accomplished by matching the number of service clock pulses in a network reference clock period at the transmitter and receiver. In one embodiment the transmitter need only send a counter value from a counter that is clocked and reset, respectively, by the service clock and network reference clock, thereby allowing use of different types of oscillators, both analog and digital, to be implemented at the transmitter and receiver. The technique is also general enough to be applied in a wide variety of packet networks including but not limited to IP, MPLS and Ethernet. In an alternative embodiment, a faster derived network clock fdnc drives both the transmitter and receiver counters, which in turn are reset, respectively by the slower transmitter service clock fsc and slower receiver service clock frc.

摘要： The invention includes a technique for clock recovery in a network having master and slave clocks in respective Time Division Multiplexing (“TDM”) network segments which are interconnected by a non-TDM segment. Master clock timestamps are sent to the slave. The slave measures a master clock timestamp inter-arrival interval, and sends slave clock timestamps to the master. The master measures a slave clock timestamp inter-arrival interval, and sends that slave clock timestamp inter-arrival interval to the slave. The slave then calculates an error signal based at least in-part on the difference between the master clock timestamp inter-arrival interval and the slave clock timestamp inter-arrival interval, and employs the difference to recover the first service clock in the second TDM segment.

摘要： A system in which data signatures are used to identify copyrighted content passing through a network. The data signatures are derived from files containing copyrighted content to be identified. The signatures are used to search within peer-to-peer data streams flowing through one or more network nodes in a communications network. Any specific technique may be used for pattern recognition between the signatures and the monitored traffic. When a particular file of interest is identified, the system may operate to perform one or more of several possible actions, including stopping the transmission, allowing the transmission but recording the event, making an offer to the recipient allowing them to legally purchase the file, or sending alternative information or intentionally corrupting the information to render it useless to the recipient.

摘要： Disclosed is an Active Queue Management method and apparatus which uses traffic rate information for congestion control. Using a nonlinear fluid-flow model of Traffic Control Protocol, a proportional-integral controller in a closed loop configuration with gain settings characterized for stable operation allows a matching of the aggregate rate of the active TCP connections to the available capacity. Further disclosed is a method for calculation of the regime of gain settings for which stable operation of a given network obtains. This approach allows for capacity matching while maintaining minimal queue size and high link utilization.
