Heterogeneous capabilities in an overlay fabric may be provided. First, it may be determined that a first link and a second link support a feature. Then the first link and the second link may be traversed with traffic between a host in a first Endpoint Group (EPG) connected to a first leaf switch and a second host in a second EPG connected to a second leaf switch when a topology preference for the feature is indicated for the traffic.

A system for inter-process communication (IPC) in a network of a vehicle through a port for communication between a source application and a destination application.

Techniques for a hub node, provisioned in a site of a hub and spoke overlay network, to receive, store, and/or forward network routing information associated with a spoke, and send packets directly to spoke(s) that are remote from the hub node. A first hub node may receive a network advertisement including a border gateway protocol (BGP) large community string from a first spoke local to the first hub node. The first hub node may send the BGP large community string to a second hub node remote from the first hub node. The second hub node may decode network routing information from the BGP large community string and store the network routing information locally. The second hub node may send a packet from a second spoke local to the second hub node directly to the first spoke without the data packet being routed via the first hub node.

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 chassis front-end is disclosed. The chassis front-end may include a switchboard including an Ethernet switch, a Baseboard Management Controller, and a mid-plane connector. The chassis front-end may also include a mid-plane including at least one storage device connector and a speed logic to inform at least one storage device of an Ethernet speed of the chassis front-end. The Ethernet speeds may vary.

Methods and systems are provided for providing secure Ethernet transmissions. In some aspects, an autonomous vehicle system is provided and can include a first system-on-chip being configured to provide data to a second system-on-chip via an Ethernet harness, a first switch being configured to: receive the data from the first system-on-chip, and provide the data to a first transceiver for transmission to the second system-on-chip, the first switch being configured to provide first transmission data to the first transceiver and to prohibit receipt of retrieval data from the second system-on-chip, and the first transceiver configured to communicate with the second system-on-chip via the Ethernet harness.

An operation method of a first communication node comprises: receiving a first frame from a second communication node; obtaining a destination address of the first frame; and transmitting a second frame including an indicator for indicating an occurrence of an error in the first frame to a communication node corresponding to a source address of the first frame, when a port corresponding to the destination address does not exist in a routing table.

A switch device includes a plurality of communication ports; a switch unit configured to relay a frame, which has been transmitted from a function unit and to which information including an ID of a VLAN is added, to another function unit via a communication port; and a duplication unit configured to, when the diagnosis device is connected to another switch device, duplicate the frame to be relayed via a designated communication port among the plurality of communication ports, and generate a duplicate frame for diagnosis that is a frame obtained by adding, to a duplicate frame obtained through the duplication, specific information indicating that the duplicate frame for diagnosis should be transmitted to the diagnosis device. The switch unit outputs the duplicate frame for diagnosis generated by the duplication unit from a communication port corresponding to the other switch device.

Certain embodiments described herein are generally directed to configuring a generic channel for exchanging information between a hypervisor and a virtual machine run by the hypervisor that resides on a host machine. In some embodiments, the generic channel represents a network or communication path enabled by a logical switch that connects a HyperBus running on the hypervisor and a node agent running on the virtual machine. In some embodiments, network traffic handled by the generic channel is isolated from incoming and outgoing network traffic between the virtual machine and one or more other virtual machines or hosts.

A link state packet transmission method and a routing node are disclosed. The method is applied to a tree topology, where the tree topology includes a leaf routing node, an intermediate routing node, and a root routing node. The method includes: receiving, by the intermediate routing node, a link state packet sent by a child routing node of the intermediate routing node; sending, by the intermediate routing node, the link state packet to the root routing node, where the root routing node is configured to aggregate received link state packets to obtain a link state packet set; receiving, by the intermediate routing node, the link state packet set sent by the root routing node; and sending, by the intermediate routing node, the link state packet set to the child routing node of the intermediate routing node.
