摘要： A safety mechanism device includes measuring whether a first output signal or results meets dynamically adjustable boundary criterion. The safety mechanism compares the first output signal with at least one boundary signal that is dynamically adjusted. The safety mechanism can produce a dynamically or automatically adjusted boundary signal using a second output signal. The second output signal can mimic the first output signal.

摘要： An approach for establishing a priority ranking for endpoints in a network. This can be useful when triaging endpoints after an endpoint becomes compromised. Ensuring that the most critical and vulnerable endpoints are triaged first can help maintain network stability and mitigate damage to endpoints in the network after an endpoint is compromised. The present technology involves determining a criticality ranking and a secondary value for a first endpoint in a datacenter. The criticality ranking and secondary value can be combined to form priority ranking for the first endpoint which can then be compared to a priority ranking for a second endpoint to determine if the first endpoint or the second endpoint should be triaged first.

摘要： A method includes capturing first data associated with a first packet flow originating from a first host using a first capture agent deployed at the first host to yield first flow data, capturing second data associated with a second packet flow originating from the first host from a second capture agent deployed on a second host to yield second flow data and comparing the first flow data and the second flow data to yield a difference. When the difference is above a threshold value, the method includes determining that the second packet flow was transmitted by a component that bypassed an operating stack of the first host or a packet capture agent at the device to yield a determination, detecting that hidden network traffic exists, and predicting a malware issue with the first host based on the determination.

摘要： A method and device for increasing an accuracy of a phase measurement, wherein the method includes: receiving a measurement signal; performing a frequency-domain transformation to the measurement signal to obtain a frequency-domain measurement sequence; determining phases that correspond to frequency-domain measurement signals, and determining a phase difference between the frequency-domain measurement signals that correspond to two neighboring specified frequency points; according to the phases, the phase difference and a window function, performing a sliding-window-type phase fitting to the frequency-domain measurement sequence, to obtain phase-fitting data that correspond to sliding windows; and according to the phase-fitting data of the sliding windows, determining phase-calibration data that correspond to the sliding windows, and, by using the phase-calibration data of the sliding windows, forming phase-calibration data within a specified frequency band. The method reduces an error of fitting, and increases an accuracy of a phase calibration.

摘要： In a cable network, embodiments detect and remediate a non-responsive customer premise equipment (CPE) device in a customer's premise with minimal or no interaction with a customer. Embodiments may detect and remediate a non-responsive CPE device without rebooting the non-responsive CPE device or the associated cable modem. Embodiments include troubleshooting a data link layer (e.g., Open System Interconnection (OSI) layer 2, or media access control (MAC) layer) and a network layer (e.g., OSI layer 3, or Internet layer) between a service operator network and the non-responsive CPE device. Embodiments include a guided integration and a proactive integration method, computer program product, and system to reduce and/or eliminate the need for a customer service representative to reboot a cable modem, and/or for a customer to reboot a non-responsive CPE device resulting in a fast and less disruptive service experience for the customer.
