Problems solved by technology

However, the two methods have their own disadvantages: Communication through method ① requires the purchase of external switching devices and physical connections, which increases the cost and network complexity; communication through method ② inevitably causes overhead of system resources (such as CPU resources), which in turn will affect communication efficiency and virtual machine performance

Embodiment Construction

[0045] In the following description, many technical details are proposed in order to enable readers to better understand the application. However, those skilled in the art can understand that even without these technical details and various changes and modifications based on the following implementation modes, it is still the technical solution claimed by the claims of the present application.

[0046] In order to make the purpose, technical solution and advantages of the present invention more clear, the following will take the "Array virtualization management platform" developed by Huayao (China) Technology Co., Ltd. as an example, and further describe the implementation of the present invention in detail in conjunction with the accompanying drawings .

[0047] A bridging method based on VF promiscuous mode comprises the following steps:

[0048] Step 1, such as image 3 As shown, on the system platform based on the VF promiscuous mode, it is set to support the Bridge mode...

Abstract

The invention provides a bridging method based on a VF promiscuous mode. The bridging method is achieved through the steps of setting to support the VF promiscuous mode, setting to support a sniffingmode, enabling the VF promiscuous mode and configuring built-in bridging mode support port mirror. The invention further provides a built-in bridging system supporting the VF promiscuous mode. By adopting the built-in bridging method in an SR-IOV promiscuous mode, PFs can be directly called, and therefore the performances of virtual machines approach to those of physical machines; the method can support the mode of deploying multiple types of the virtual machines, support to control the multiple mode (unicast, multicast, broadcast, VLAN) promiscuous mode of a single VF, achieves a hardware network card-based built-in switch function and has the advantages of being high in performance, not occupying system resources such as a CPU and a memory, reducing the cost and the network complexity and the like.

Description

technical field [0001] The present invention relates to the field of virtual technology in network application delivery control, in particular to a built-in bridging method and system based on VF (Virtual Function, virtual function, hereinafter referred to as VF) hybrid mode. Background technique [0002] VF promiscuous mode (promiscuous): that is, all the data packets sent to the PF for unicast, multicast, broadcast or specified vlan (Virtual Local Area Network Virtual Local Area Network) are sent to the specified VF. [0003] SR-IOV (Single Root I / O Virtualization) technology is a hardware-based virtualization solution that improves performance and scalability. The SR-IOV standard allows efficient sharing of PCIe (Peripheral Component Interconnect Express, fast peripheral component interconnection) devices between virtual machines, and it is implemented in hardware to obtain I / O performance comparable to native performance. According to the SR-IOV standard, new devices ar...
