Apparatuses, methods, and computer-readable media are provided for operating a port manager to detect a first link condition or a second link condition of a circuitry. Under the first link condition, a first link between a downstream port of the circuitry and an upstream port of a switch is compatible to a first protocol, and a second link between a downstream port of the switch and an upstream port of a device is compatible to the second protocol. Under the second link condition, the first link exists and is compatible to the first protocol, while there is no second link being compatible to the second protocol. The port manager is to operate the downstream port of the circuitry according to the second protocol on detection of the first link condition, or according to the first protocol on detection of the second link condition. Other embodiments may be described and/or claimed.

Systems and methods for interoperating between real time networks. Systems may include a plurality of ports and switch circuitry coupled to the plurality of ports. At least one port may be coupled to a first real time network carrying first traffic. One or more other ports may be coupled to a second real time network carrying second traffic. Switch circuitry may route packets between the first real time network and the one or more second real time networks based on a mapping. Routing information may be inserted in packets routed from the one or more second real time networks to the first real time network and routing information may be removed from the packets routed from the first real time network to the one or more second real time networks. Packets may be routed based on the mapping to distinct queues for the first and second traffic.

A mechanism is provided for reducing network load in a software defined network. The mechanism is executed by a virtual machine hypervisor. The mechanism receives a network broadcast request sent by a source virtual machine node; acquires a first destination address in the network broadcast request; and reads a predefined mapping rule of the first destination address and a second destination address. An address of a node in the software defined network is configured by using the predefined mapping rule. The mechanism derives the second destination address corresponding to the first destination address according to the mapping rule. The mechanism responds to the network broadcast request by using the derived second destination address.

A method for vehicle diagnostics, a diagnostic device, and a non-transitory computer-readable storage medium are provided in the present disclosure.
