A parent PCE controller comprising a memory comprising instructions executable by a processor and a processor coupled to the memory and configured to execute the instructions. Executing the instructions causes the processor to establish a parent-child relationship with at least a first child PCE controller controlling a first domain and a second child PCE controller controlling a second domain, receive a request to create an E2E tunnel from a source to a destination crossing the first domain and the second domain, compute a shortest path from the source to the destination through the first domain and the second domain, transmit a request message to the first child PCE controller for creating a first tunnel segment of the E2E tunnel through the first domain, and transmit a request message to the second child PCE controller for creating a second tunnel segment of the E2E tunnel through the second domain.

A network hub is provided for an onboard network system. The onboard network system includes first and second networks for transmission of first-type and second-type frames following first and second communication protocols. The network hub includes a receiver that receives a first-type frame. A processor determines whether or not the first-type frame received by the receiver includes first information that is a base for a second-type frame to be transmitted to the second network, to obtain a determination result, and selects a port to send a frame based on the first-type frame based on the determination result. A transmitter sends the frame based on the first-type frame to a wired transmission path connected to the port selected by the processor based on the first-type frame received by the receiver.

An electric vehicle is provided, equipped with a communication network including: at least one communication bus, called main communication bus; and at least two subnetworks, each subnetwork carrying out a communication with at least two components of the vehicle; each subnetwork including a communication node connecting the subnetwork to the main bus; and the communication network includes a subnetwork dedicated to communicating with the rechargeable electrical energy storage modules.

A method of broadcasting firmware updating messages in a communication system includes the steps of receiving a broadcast remote firmware update (BRFU) setup message from an upstream source, the BRFU setup message specifying a number of transmissions of a broadcast of a firmware file; broadcasting setup information from the BRFU setup message on a first channel to downstream devices, the setup information specifying at least one other channel to which each downstream device should listen to receive a copy of the firmware file; and repeatedly broadcasting the firmware file to the downstream devices in accordance with the BRFU setup message.

A hub apparatus and a method for controlling the same are provided for efficiently managing a frequency slot or a time slot in communication between at least one hub apparatus and at least one device. The hub apparatus includes a communicator configured to receive a communication signal from at least one device; a controller configured to allocate time slots for the at least one device on the basis of the communication signal received from the at least one device, and when the communicator receives a communication signal from a new device other than the at least one device, transmit a control signal for reallocating time slots for at least one device having the new device; and a memory configured to store data that is associated with a communication frequency, a use amount of time slots, and a communication signal strength of the at least one device.

A method is provided for protecting a vehicle network of a vehicle against manipulated data transmission, in which the vehicle network includes multiple network nodes, and at least one first network node in the vehicle network in a normal mode checking a first received message as to whether the first received message is a message assigned to the first network node in the normal mode, but which the first network node did not transmit. The first network node in a diagnostic mode further checks a second received message as to whether the second received message is a message assigned to the first network node in the normal mode or in the diagnostic mode, but which the first network node did not transmit.

One or more techniques and/or systems are provided for network isolation. For example, nodes within a mesh of devices may be configured with routing rules, main routing tables, and alternative routing tables, such as at a layer-3 network layer. The routing rules may specify that packets received from downstream are to be routed upstream to either a gateway or a backhaul device for evaluation as to whether such packets are allowed to be communicated back downstream to destination recipients using main routing tables. An isolation rule may be configured to specify whether to block or allow packets. In an example, the gateway may either block or allow packets based upon whether a source and destination are within a same virtual local area network or are within different virtual local area networks. In this way, selective device isolation may be provided, such as at the layer-3 network layer.

Systems and methods for implementing power management features while providing a wireless asymmetric network are disclosed herein. In one embodiment, a system includes a hub having a wireless control device that is configured to control communications and power consumption in the wireless asymmetric network architecture and sensor nodes each having at least one sensor and a wireless device with a transmitter and a receiver to enable bi-directional communications with the wireless control device of the hub. The wireless control device is configured to determine a scheduled timing of operating each sensor node during a first time period that is close in time with respect to a transmit window of the transmitter and during a second time period that is close in time with respect to a receive window of the receiver for each wireless device to reduce power consumption of the wireless devices of the sensor nodes.

A patient parameter communication hub includes a plurality of patient-parameter-connectors, a data conversion unit, a medical-analysis station connector, and a data-network connector. The plurality of patient-parameter-connectors are adapted for receiving physiological parameter data in a first format. The physiological parameter data are generated by one or more physiological parameter data generators. The data conversion unit is adapted for converting the received physiological parameter data from the first format to a second format. The medical-analysis station connector is adapted for transmitting the received physiological parameter data in the second format to a medical-analysis station for processing and for receiving processed physiological parameter data in the second format from the medical-analysis station. The data-network connector adapted for transmitting the received processed physiological parameter data in the second format over a data-network to one or more destinations. Related apparatus, systems, techniques, and articles are also described.

A system includes: a first telephone; a relay that manages first accommodation position information of the first telephone; and an exchange that includes a management table that manages second telephone identification information, second accommodation position information of a second telephone connected to the relay, and an extension number of each of a plurality of the second telephones, receives first telephone identification information and the first accommodation position information, when the first telephone identification information does not match with any one of the second telephone identification information registered, and the first accommodation position information matches with one of the second accommodation position information in the management table, changes second telephone identification information corresponding to the matched second accommodation position information to the first telephone identification information, and uses an extension number corresponding to the matched second accommodation position information as an extension number of the first telephone.
