Description

Information Processing Transmission Device

technical field

The present invention relates to an information processing and transmission device, in particular to an information processing and transmission device with multiple operating systems that cooperate with an information processing unit to run and obtain required network resources respectively.

Background technique

One of the architectures of existing information devices is that two processor cores cooperate with a single operating system to perform respective computing tasks (that is, each processor core executes one or more computing tasks), and this The operating system connects to the network through a single physical network connection device (ie, a network card) to allocate network resources required by the two processor cores to perform computing tasks. However, under the operating conditions of a single operating system, the operating system must cooperate with the scheduling of computing tasks of multiple processor cores and allocate the network resources required for multiple computing tasks, so that the burden of the operating system is too high and the information The overall operating performance of the device is limited and not ideal.

Another architecture of the existing information device is that on the architecture of Symmetric Multiprocessing (SMP, Symmetric Multiprocessing), through the establishment of a virtual machine monitor (VMM, Virtual Machine Monitor, that is, Hypervisor), the process (Process) can be The movement between different processors, specifically, the virtual machine monitor creates two guest operating systems (Guest Operating System) in the form of bare-metal virtualization (Bare-Metal); the two guest operating systems cooperate with the information device accordingly The two processor cores operate separately, and the virtual machine monitor is connected to the network through a single physical network connection device to provide network resources required by the two guest operating systems respectively. However, if the information device wants to control the hardware of the information device (including processor core, memory, hard disk, physical network connection device) and manage the guest operating system through the virtual machine monitor, the hardware of the information device must be able to support the virtual machine monitor. On the premise, the goal of making the virtual machine monitor run directly on the information device can be achieved; and, in terms of the architectural arrangement of the information device, the virtual machine monitor is set between the guest operating system and the physical network connection device so that the guest The operating system cannot be directly connected to the physical network connection device, so that the transmission efficiency of network resources is affected by the virtual machine monitor and cannot be improved. Therefore, existing information devices still have limitations in the practical application of the architecture with a virtual machine monitor.

The third structure of the existing information device is that the information device has two processor cores and two physical network connection devices, and the two processor cores cooperate with the operation of two operating systems to perform computing tasks; the two operating systems The devices are directly connected to the two physical network connection devices to connect to the network, so that the two operating systems can obtain network resources required for processing tasks. However, when the information device has other operation requirements and needs to flexibly schedule one of the physical network connection devices to connect to the network, the existing information device cannot satisfy the two operations at the same time when one of the physical network connection devices is selected. Due to the network connection requirements of the system, the structure arrangement of the existing information devices is still not perfect.
