An intrusion detection system can be embedded in an industrial controller to detect an attack on an industrial control system. The intrusion detection system can detect an attack by determining if there are anomalies related to the network traffic in the industrial control system and / or by determining if the devices (e.g., sensors and actuators) connected to the industrial controllers of the industrial control system are not operating within expected ranges. To assist in determining if the devices of the industrial control system are not operating properly, the industrial controllers can also be networked together in a peer-to-peer network that permits each industrial controller to share its state information with the other industrial controllers.

Existing session routing strategies tend to primarily focus on performance and cost efficiency, with less emphasis on energy consumption or sustainability. To address this, devices, systems, methods, and processes that facilitate sustainability-aware collaboration session activity routing are described herein. A session control logic receives attributes of a plurality of network devices and determines sustainability scores for the plurality of network devices. The session control logic further selects a target network device from the plurality of network devices based on the sustainability scores, and directs a collaboration session activity to the selected target network device. Thus, the target network device receives the collaboration session activity in response to its sustainability score being optimal in comparison to respective sustainability scores of peer network devices. As a result, the session control logic explicitly considers sustainability impact of a routing decision when determining routes, leading to improved energy efficiency or reduced environmental impact.

Devices, systems, methods, and processes for establishing peer-to-peer (P2P) networks over Wi-Fi extended spectrum. P2P networks often encounter challenges in meeting their bandwidth requirements, resulting in degraded performance, slower data transfer rates, or even connectivity issues. Therefore, by delegating frequency channels in the Wi-Fi extended spectrum for establishing P2P networks, at least some challenges faced by the P2P networks can be overcome. Access points (APs) in automated frequency coordination (AFC) infrastructure may coordinate with network devices intending to establish P2P connections and may allocate unused or underutilized channels in the Wi-Fi extended spectrum to these network devices for establishing the P2P connections. The APs may set usage conditions on the allocated channels which the network devices and the APs monitor once the P2P connections are established. The APs may further monitor network traffic on the allocated channels and allow concurrent P2P connections on the same channel to improve channel utilization.

According to the method and the device, the peer-to-peer network, the node weight and the mirror image fragmentation processing are combined, and the node with the higher node weight is selected as the node for pulling the mirror image, so that the downloading speed of the mirror image is improved, node overload is avoided, and the downloading efficiency is improved.

A system and method may facilitate data matching between multiple data owners through the use of a common set of “pseudonymized” individuals or household identifiers without requiring any data owner to share personally identifiable information with any other party. Data owners may accurately match ID-level online and offline data across multiple platforms with other participants' online and offline data without requiring any party to disclose personally identifiable information about their users or households. This use of deterministic data, rather than probabilistic data or a combination of deterministic and probabilistic data, is more accurate while also lowering the risk of data breach since no personally identifiable information is shared. Likewise, match processing time is greatly reduced through automation in a permissioned peer-to-peer network where each peer pseudonimizes its customer data with a universal or household ID to facilitate data matching with similarly pseudonimized customer data of other peers.
