Embodiment Construction

[0056] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0057] In a typical configuration of this application, the terminal, the equipment of the service network, and the trusted party all include one or more processors (CPU), input / output interfaces, network interfaces, and memory.

[0058] The memory may include non-permanent memory in a computer readable medium, random access memory (RAM) and / or non-volatile memory, such as read only memory (ROM) or flash memory (flash RAM). Memory is an example of computer readable media.

[0059] Computer-readable media includes permanent and non-permanent, removable and non-removable media, and information storage can be realized by any method or technology. The information can be computer-readable instructions, data structures, program modules, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static random access memo...

Abstract

The invention provides a network forwarding method and a device. A mailbox message mechanism of a safety net card is used, consumption of a CPU is reduced, a message transmission channel between a virtual gateway and a virtual machine is realized, while the high network forwarding performance is acquired, logic control is carried out through software, the virtual gateway is in charge of transmission of a network message between each virtual machine and a physical switch, and controllable network safety can be achieved.

Description

Technical field [0001] This application relates to the computer field, and in particular to a network forwarding method and equipment. Background technique [0002] At present, with traditional open source software, network packets are forwarded between virtual machines and physical switches, and the performance bottleneck is generally around 1 to 2 Mpps. [0003] There are two types of existing virtualized network management: [0004] 1. Use the virtual network card (vhost+virtionet) mode, this mode uses software to manage the network, and its forwarding performance is low; [0005] 2. Use the Single-Root I / O Virtualization (SRIOV, Single-Root I / O Virtualization) mode to directly pass network packets to the physical switch. This mode uses hardware to manage the network and can be close to the line It is fast, but it cannot access the content of network messages, and is only suitable for internal use. Summary of the invention [0006] One purpose of the present application is to prov...
