Abstract: An attestation framework to support attestation and anomaly detection in an electric grid. The attestation framework provides systems and methods that use distributed ledger technology (DLT) and implement DLT-based methods for verifying device and data trustworthiness on the electric grid. The framework attests to system changes and anomaly detection to flag specific events such as natural and cyber-induced grid events categorization, electrical faults in meters and relays and cyber events, e.g., based on statistical and baseline threshold values. The attestation framework can support the detection of system changes by itself, and in combination with an anomaly detection framework, has a lower system resource requirement and is more likely to catch system changes. An anomaly detection module can trigger attestation checks and uses the DLT for device and configuration verification purposes. The attestation framework can be deployed at substations or other environments, such as DERs or a microgrid.

Abstract: This application provides a data transmission method computer-readable storage medium performed by an electronic device. The method includes: obtaining a latency variation distribution characteristic of a service data packet, the latency variation distribution characteristic being configured for indicating a transmission latency range of the service data packet; detecting a network transmission characteristic between an application server (AS) and a core network gateway; adjusting the latency variation distribution characteristic of the service data packet based on the network transmission characteristic, to obtain an adjusted latency variation distribution characteristic; and transmitting the adjusted latency variation distribution characteristic to a core network element, so that the core network element controls data transmission based on the adjusted latency variation distribution characteristic.

Abstract: The described technology is generally directed towards a transport protocol for latency sensitive applications. The disclosed transport protocol is “semi-reliable” in that it allows for specification of an importance of data being transmitted, thereby allowing important data to be sent reliably, while other data can be dropped if necessary, e.g., under bad network conditions. A deadline can be specified for such other data, and if the other data cannot be sent prior to the deadline, it can be dropped. Furthermore, the disclosed transport protocol can allow for early discovery of network jitter. A client device can send regular acknowledgments which identify most recently received data packets as well as a number of “heartbeat transmissions” received at the client device. A server device can use the acknowledgments to discover and respond to jitter.

Abstract: One function of a communications network, or of nodes in such a network, is to gather data that is useful in assessing network performance, and quantifying metrics of node and/or network performance. Various embodiments disclosed herein improve the ability of nodes and networks to gather such data, and quantify metrics of node and/or network performance by selectively marking existing network traffic, and in preferred embodiments without having to dilute network traffic by generating and transmitting dummy data packets.

Abstract: An information processing device includes a reception I/F unit, a reception-time-point measuring unit, and an event-detection-time-point estimation unit. The event-detection-time-point estimation unit estimates an event detection time point, which is a time point at which an event corresponding to latest detection data is detected, from a minimum system delay time, a minimum-system-delay jitter, and a time period from detection of the event corresponding to a target data to detection of the event corresponding to latest detection data. The minimum-system-delay jitter is the difference between a minimum-reception-time expected reception time point and the reception time point of the target detection data. The minimum-reception-time expected reception time point is calculated to be a time point at which the target data is received before the latest detection data. The target detection data is one piece of detection data, out of the multiple pieces of detection data, sent with a minimum system delay time.

Abstract: Some embodiments provide a method for quantifying quality of several service classes provided by a link between first and second forwarding nodes in a wide area network (WAN). At a first forwarding node, the method computes and stores first and second path quality metric (PQM) values based on packets sent from the second forwarding node for the first and second service classes. The different service classes in some embodiments are associated with different quality of service (QoS) guarantees that the WAN offers to the packets. In some embodiments, the computed PQM value for each service class quantifies the QoS provided to packets processed through the service class. In some embodiments, the first forwarding node adjusts the first and second PQM values as it processes more packets associated with the first and second service classes. The first forwarding node also periodically forwards to the second forwarding node the first and second PQM values that it maintains for the first and second service classes. In some embodiments, the second forwarding node performs a similar set of operations to compute first and second PQM values for packets sent from the first forwarding node for the first and second service classes, and to provide these PQM values to the first forwarding node periodically.

Abstract: A method is disclosed for distributed routing data with latencies using relay nodes. The method includes automatically measuring one-way latencies between a plurality of nodes comprising a first node, a second node, and a relay node, producing a first signal associated with a proof of uptime for the relay node, producing a second signal associated with a proof of bandwidth for the relay node, after the proof of uptime and the proof of bandwidth of the relay node are validated, automatically identifying a relayed data routing path from the first node to the second node via the relay node based on the one-way latencies between the plurality of nodes, in response to a command to transfer data from the first node to the second node, and transferring data from the first node to the second node along the relayed data routing path.

Abstract: Methods and systems are provided for latency-oriented router. An incoming packet is received on a first interface. The type of the incoming packet is determined. Upon the detection that the incoming packet belongs to latency-critical traffic, the incoming packet is duplicated into one or more copies. Subsequently, the duplicated copies are sent to a second interface in a delayed fashion where the duplicated copies are spread over a time period. The duplicated copies are received and processed at the second interface.
