摘要： Determining a bit rate at which to deliver a packet stream over a network link. An origin device transmits over the network link unsolicited data packets to a destination device while contemporaneously transmitting over the network link a first packet stream encoded at an initial bit rate to the destination device. The origin device may be, but need not be, a content delivery network (CDN) edge node and the destination device may be, but need not be, a cable modem (CM). The origin device determines whether the network link supports delivering a second packet stream in lieu of the first packet stream encoded at a higher bit rate based, at least in part, on an amount of retransmission requests the origin device receives for packets in the first packet stream from the destination device.

摘要： A method for measuring a schedule update time of a time aware shaper DUT includes configuring the DUT with a first configuration that blocks traffic from at least one gate of the DUT. The method further includes transmitting traffic from an emulated talker to an emulated listener via the DUT. The method further includes confirming blocking of the traffic from the at least one gate of the DUT and transmitting a second configuration from an emulated CNC node to the DUT, where the second configuration opens the at least one gate of the DUT, recording a time T1 of transmission of the second configuration to the DUT, detecting traffic from the at least one gate of the DUT at the listener, recording a time T2 of receipt of the traffic at the listener, and calculating a response time of the DUT to the second configuration based on T1 and T2.

摘要： A system for generating and applying a secure token in a resource distribution network is provided. For example, a headend system generates a payment-based token based on a payment made for a meter. The payment-based token indicates a credit value to be applied to the meter. The credit value can range between a negative limit and a positive limit. The payment-based token is further generated based on a meter identifier. The headend system transmits the payment-based token to the meter via at least a mesh network. After receiving the payment-based token, the meter validates the token to determine that the token is generated for the meter. The meter further determines the balance associated with the meter based on the credit value specified in the token. Based on the balance, the meter connects or disconnects premises associated with the meter from a resource supply.

摘要： A method of diagnosing faults in a utility supply network involves receiving performance data indicative of performance of the utility supply network, and receiving historical performance data indicative of a historical performance of the utility supply network and a fault associated with the historical performance data. A fault in the utility supply network is determined based on a comparison of the performance data with the historical performance data.
