Sync Network
20210194793 · 2021-06-24 ·

The provision of redundancy in a sync network, which protects the sync network against faults, such as broken cables in the sync network. The gateway comprises a sync propagation module configured to provide redundant sync requests that are sent along different pathways in the sync network. These sync requests are sent to towards different masters in the sync network. If a fault occurs at a point in one of the paths, the gateway will still receive a sync acknowledgment returned along the other path. Furthermore, the use of redundant sync networks, propagating the sync requests across different paths, allows fault detection in the wiring to be detected.

ANOMALY DETECTION METHOD AND ANOMALY DETECTION DEVICE

In an anomaly detection method that determines whether each frame in observation data constituted by a collection of frames sent and received over a communication network system is anomalous, a difference between a data distribution of a feature amount extracted from the frame in the observation data and a data distribution for a collection of frames sent and received over the communication network system, obtained at a different timing from the observation data, is calculated. A frame having a feature amount for which the difference is predetermined value or higher is determined to be an anomalous frame. An anomaly contribution level of feature amounts extracted from the frame determined to be an anomalous frame is calculated, and an anomalous payload part, which is at least one part of the payload corresponding to the feature amount for which the anomaly contribution level is at least the predetermined value, is output.

Diagnosing cable faults within a network

Various embodiments relate to detecting a cable fault within a 10SPE network. A method may include transmitting a pulse signal to a cable of a shared bus from a node, and observing a signal received at the node in response to the pulse signal. The method may also include determining a fault condition of the cable based on the pulse signal and on an amplitude of each sample of a number of samples of the one or more observed signals.
