On-board communication system, switching device, verification method, and verification program
An on-vehicle communication system includes: a plurality of function units; and one or a plurality of switch devices, each switch device being configured to perform a relay process of relaying communication data between the function units. When unauthorized communication by a function unit has been detected, the switch device performs a validation process of validating a function unit other than an unauthorized-communication function unit that is the function unit for which the unauthorized communication has been detected.
WIND TURBINE, WIND TURBINE COMMUNICATION SYSTEM, AND METHOD FOR OPERATING A BUS SYSTEM
A wind turbine having a Controller Area Network communication system is provided. Electrical and/or electronic components of the wind turbine are coupled to CAN nodes. The communication system has a plurality of CAN nodes. At least one CAN distributor unit is coupled via a first communication segment to one of the plurality of CAN nodes and via a second communication segment to at least one further CAN distributing unit. The CAN distributor units are designed to carry out a data communication via the first communication segment on the basis of a first CAN protocol which represents a standard CAN protocol, and to carry out a data communication via a second communication segment on the basis of a second CAN protocol which is different from the standard CAN protocol.
LAYER 3 CONVERGENCE FOR EVPN LINK FAILURE
A network device is configured to provide, via an Ethernet segment with a customer network, active-active multi-homing L2 virtual bridge connectivity to the customer network using an EVPN instance (EVI) and L3 routing using an IRB interface that is a L3 routing interface assigned to the EVI; to receive, from a peer PE device of the EVPN instance, an EVPN route comprising an L2-L3 binding for a customer device of the customer network and associating the L2-L3 binding with the Ethernet segment, the L2-L3 binding comprising an L2 and an L3 address assigned to the customer device, wherein the peer PE device provides, with the network device and via the Ethernet segment, active-active multi-homing L2 virtual bridge connectivity to the customer network; and to forward, via the Ethernet segment and based at least on the L2-L3 binding received from the peer PE device, an L3 packet to the customer device.
Data Packet Transmission Method and Border Routing Bridge Device
A data packet transmission method and a border routing bridge device, where the method includes receiving, by a first border routing bridge device of a first area, a first data packet sent by a border routing bridge device of a second area to the first area, determining, a device identifier group of the second area according to the first data packet, determining, from the device identifier group of the second area, according to the first data packet, a device identifier of a border routing bridge device used to forward a return data packet sent by the target device to the source device, and sending, by the first border routing bridge device, a second data packet carrying the determined device identifier to the target device, where the determined device identifier is used as a source routing bridge device identifier of the second data packet.
Host Routed Overlay with Deterministic Host Learning and Localized Integrated Routing and Bridging
Systems, methods, and devices for improved routing operations in a network computing environment. A system includes a virtual customer edge router and a host routed overlay comprising a plurality of host virtual machines. The system includes a routed uplink from the virtual customer edge router to one or more of the plurality of leaf nodes. The system is such that the virtual customer edge router is configured to provide localized integrated routing and bridging (IRB) service for the plurality of host virtual machines of the host routed overlay.
INTEGRATED HUB SYSTEMS CONTROL INTERFACES AND CONNECTIONS
Systems, methods, and instrumentalities are disclosed for switching a control scheme to control a set of system modules and/or modular devices of a surgical hub. A surgical hub may determine a first control scheme that is configured to control a set of system modules and/or modular devices. The surgical hub may receive an input from one of the set of modules or a device located in an OR. The surgical hub may make a determination that at least one of a safety status level or an overload status level of the surgical hub is higher than its threshold value. Based on at least the received input and the determination, the surgical hub may determine a second control scheme to be used to control the set of system modules. The surgical hub may send a control program indicating the second control scheme to one or more system modules and/or modular devices.
NEGOTIATED BRIDGE ASSURANCE IN A STACKED CHASSIS
An information handling system includes multiple data ports, a memory, and a processor. Each of the data ports enables a separate communication link of a plurality of communication links for the information handling system. The memory stores data to indicate whether the information handling system supports bridge assurance on each of the communication links. In response to the bridge assurance being supported in the information handling system, the processor provides a message across a first link of the communication links. The message indicates that bridge assurance is supported in the information handling system. The processor also determines whether an acknowledgement message has been received. In response to the acknowledgement message being received, the processor enables the bridge assurance on the first link.
DYNAMIC CELLULAR CONNECTIVITY BETWEEN THE HYPERVISORS AND VIRTUAL MACHINES
Systems, methods, and computer-readable media for requesting a cellular IP address by initiating a call with a modem, establishing data packet network connectivity with the cellular IP address, assigning the cellular IP address to a virtual L2-bridge interface, wherein the virtual L2-bridge interface includes a MAC address, mapping a MAC address of a virtual machine with the MAC address of the virtual L2-bridge interface, detecting a change in the cellular IP address, and updating the virtual L2-bridge interface with a different cellular IP address while maintaining the data packet network connectivity.
Automation network, network distributor and method for transmitting data
An automation network with network subscribers is provided, in which the network subscribers are interconnected via a data line network. At least one network subscriber is configured as a master subscriber, which is adapted to send telegrams via the data line network. At least one network subscriber is configured as a network distributor, which is adapted to route telegrams. The network distributor has a plurality of input/output ports, and is connected to the master subscriber via a first input/output and data line network. The master subscriber is configured to use a telegram element to indicate that the telegram is enabled for processing by the network subscribers. In addition, the network distributor is configured to process a telegram received via the first input/output port when the telegram element indicates enablement of processing of the telegram by the network subscribers.
MACsec Key Exchange Attribute Reflection for Transparent Provider Backbone Bridge Forwarding Over Public Ethernet Provider Backbones
The present disclosure is directed to systems and methods for transparent Provider Backbone Bridge forwarding of MACsec key exchanges over public Ethernet provider backbones. The method includes the steps of receiving, at a first PBB device, an Ethernet frame from a first edge router for transmission to a second edge router via a MACsec connection, the Ethernet frame comprising a plurality of fields; performing a lookup of one or more fields of the plurality of fields to determine a match with one or more pre-defined values; determining that the one or more fields of the Ethernet frame match the one or more pre-defined values; rewriting the one or more fields of the Ethernet frame to one or more open values operable to allow the Ethernet frame to be transmitted to a next hop device; and transmitting the Ethernet frame to the next hop device.
