Network architecture, corresponding vehicle and method

A method, comprising:

• controlling exchange of information comprising data flow transmission to virtual machine ports (VMPs) over a data link via media access control (MAC) controller circuitry to provide a MAC port layer;
• handling transmission data flow to the VMPs via virtual machine transmission (VM Tx) bridge circuitry;
• routing or switching data flow from the MAC controller circuitry to the VM Tx bridge circuitry via transmission router/switch circuitry;
• providing queue management for data flow between the MAC controller circuitry and the VM Tx bridge circuitry via queue handler circuitry, wherein the transmission router/switch circuitry is coupled between the MAC controller circuitry and the queue handler circuitry;
• and
• implementing virtualization of router or switch in the transmission router/switch circuitry via virtual destination address circuitry in the VM Tx bridge circuitry with a virtual machine transmission descriptor that is based on a combination of (a) a virtual machine port (VMP) tag indicative of a physical resource in the queue handler circuitry selectable for data flow transmission, and (b) a virtual machine extended identifier (VMEID).

A collection of non-transitory computer-readable media storing contents that, when executed by one or more processors, cause a method to be performed, the method comprising:

• controlling exchange of information comprising data flow transmission to virtual machine ports (VMPs) over a data link via media access control (MAC) controller circuitry to provide a MAC port layer;
• handling transmission data flow to the VMPs via virtual machine transmission (VM Tx) bridge circuitry;
• routing or switching data flow from the MAC controller circuitry to the VM Tx bridge circuitry via transmission router/switch circuitry;
• providing queue management for data flow between the MAC controller circuitry and the VM Tx bridge circuitry via queue handler circuitry, wherein the transmission router/switch circuitry is coupled between the MAC controller circuitry and the queue handler circuitry;
• and
• implementing virtualization of router or switch in the transmission router/switch circuitry via virtual destination address circuitry in the VM Tx bridge circuitry with a virtual machine transmission descriptor that is based on a combination of (a) a virtual machine port (VMP) tag indicative of a physical resource in the queue handler circuitry selectable for data flow transmission, and (b) a virtual machine extended identifier (VMEID).
