Abstract

The invention relates to a network interface controller (NIC) sharing method, the method being implemented by a virtual machine (RTOS VM) running Real-Time Operating Systems (RTOS) in charge of executing time critical tasks, the method comprising: - implementing (S01), by the RTOS, a hardware driver (NICd) for exclusively driving the NIC from the RTOS, - implementing (S02), by the RTOS, a backend driver (BE-vNIC) for driving a virtual NIC (vNIC) from said RTOS, the backend driver (BE-vNIC) enabling receiving and transmitting network frames to at least one user virtual machine, each of the at least one user virtual machine using an at least one corresponding frontend driver, - the RTOS setting (S03) at least one shared memory region (SMR) of a memory space dedicated to the RTOS VM, to store and exchange the network frames of the at least one user virtual machine for enabling the backend driver (BE-vNIC) to exchange the network frames with the at least one frontend driver.
