A transceiver is disclosed. The transceiver includes a first receiver line, a first transmitter line, a second receiver line, and a second transmitter line, wherein the first receiver line and the second receiver line are coupled to a receiver line selector and the first transmitter line and the second transmitter line are coupled to a transmitter line selector. A system monitor is included that is configured to monitor a controller area network (CAN) bus and the first transmitter line and to select the second transmitter line and the second receiver line if an error condition is detected through the monitoring of the first transmission line. A bias voltage generator is included to generate a bias voltage for a terminating capacitor of the CAN bus, wherein the bias voltage generator is activated by the system monitor when an error condition is detected in the CAN bus.

A Fibre Channel Forwarder (FCF) routing system includes a target device coupled to a Fibre Channel (FC) networking device via a first link, and a Fibre Channel Forwarder (FCF) device that is coupled to an initiator device via a second link, the FC networking device via a third link that is mapped to the second link, and the FC networking device via a fourth link that is mapped to the second link. The FCF device receives, via the second link, first traffic that originates from the initiator device and that is addressed to the target device. The FCF device determines, using an initiator device identifier included in the first traffic and a link mapping table, that the third link and the fourth link are mapped to the second link on which the first traffic was received and load balances the first traffic between the third link and the fourth link.

A remote terminal adapter device is disclosed. The adapter device includes control processors in communication with a bus controller via a dual redundant data bus (e.g., MIL-STD-1553) having primary and secondary data buses or channels. The adapter device includes analog relays connecting the primary and secondary buses to a main remote terminal (RT) device configured for control of an aircraft subsystem. Additional analog relays connect the data bus to one or more auxiliary or additional RTs (e.g., configured to backup the main RT or simulate the controlled subsystem and its responses. The adapter device may monitor the data bus for traffic and allow the redundant RT to access the data bus (from the same remote terminal) address as the main RT by activating and deactivating the analog relays.

A redundant system includes devices communicably coupled via communication paths. Each device is communicably coupled via two or more of the communication paths to two or more of the other devices. Each device performs wired communication via the communication paths with the devices communicably coupled to the each device via the communication paths in a normal state. Each device includes a wireless communication unit. When each device communicates with the two or more of the other devices under a condition that malfunction occurs in two or more parts in the redundant system, the each device performs the wired communication via the communication path with a counterpart device with which the wired communication via the communication path is enabled, and switches from the wired communication via the communication path to wireless communication and continues communication with the counterpart device with which the wired communication via the communication path is disabled.

A plurality of signal lines connects a first controller and a second controller to each other. The first controller supplies a plurality of first control signals for controlling an actuator for controlling the second controller through a plurality of signal lines and performs an abnormality diagnosis of each of the plurality of first control signals. The second controller outputs a second control signal for controlling the actuator based on a plurality of first control signals supplied from the first controller through the signal lines and diagnosis results of the plurality of first control signals obtained by the first controller.

A storage system has priority queues for real time-class file system messaging and backup-class file system messaging. The storage system includes servers, coupled as a storage cluster, storage devices and a network coupling the servers and the storage devices. The servers have priority queues. The servers operate the priority queues for messaging from the servers to the storage devices via the network in accordance with a real time-class file system and a backup-class file system. A first subset of the priority queues has higher priority on the network for real time-class file system messaging of at least one type. A second subset of the priority queues has lower priority on the network for backup-class file system messaging of at least one type.

Systems and techniques for digital twin framework for next generation networks are described herein. A digital twin model may be generated for physical nodes of an edge network. The digital twin model may include a digital twin for a physical node of the physical nodes. An error may be identified of the physical node or the digital twin for the physical node. The digital twin model may be updated to halt communication with the physical node or the digital twin of the physical node. A path may be created to another physical node or a digital twin of the another physical node in the digital twin model.

A biometrics hub may establish a session with a first biometric device, receive first biometric data of a user from the first biometric device, establish a session with a second biometric device, receive second biometric data of the user from the second biometric device, and store the first biometric data and the second biometric data at the biometrics hub. The biometrics hub may further detect a power event associated with at least one of the first biometric device or the second biometric device, and change, in response to detecting the power event, a schedule for processing at least one of the first biometric data or the second biometric data.

An apparatus in one embodiment includes at least one processing device, with the at least one processing device comprising a processor and a memory coupled to the processor. The at least one processing device is configured to monitor performance of respective ones of a plurality of paths for accessing a logical storage device, and responsive to detection of at least one specified condition in the monitored performance relating to at least a subset of the paths, to switch the logical storage device from utilization of a first access protocol to utilization of a second access protocol different than the first access protocol. For example, in some embodiments, the at least one processing device is configured to switch the logical storage device from a SCSI access protocol to an NVMe access protocol, and vice versa, responsive to congestion, errors or other detected performance conditions currently impacting one of the access protocols.

Described herein are techniques for managing failover in a data center environment interconnected using an internet small computer systems interface (iSCSI) communication protocol, the techniques including receiving, at a host and from a kernel driver, an asynchronous message comprising an indication of a failed path associated with a first node having a first port, a list of internet protocol (IP) addresses associated with a plurality of failover paths including a first failover path associated with a second node having a second port, and an expiration. The techniques further including performing, by the host and before the expiration, a first input/output (I/O) operation on the second port associated with the second node. The techniques further including performing, by the host and after the expiration, a second I/O operation on the first port of the first node.
