Multi-virtual network system and method for realizing multi-virtual network communication

Abstract

The invention provides a multi-virtual network system and a method for realizing multi-virtual network communication. According to the multi-virtual network system and the method for realizing the multi-virtual network communication, a virtual network controller is respectively coupled with a common node operating system and each access virtual network interface, and each virtual network is transmitted in the same physical network by the virtual network controller; and under the virtual network control action of the virtual network controller, isolated communication of each virtual network in logic is realized.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a multi-virtual network system and a method for realizing multi-virtual network communication. Background technique [0002] It is well known to those skilled in the art that a single computer device is connected to multiple mutually isolated networks through multiple physical network interfaces. This technology greatly improves the security of each independent network in a large and complex network, and at the same time allows a single computer device to access each independent network with access permission, which obviously meets the needs of many real-world scenarios. Network connection access requirements. However, configuring each independent network with its own network connection device hardware (such as a network card, switch, etc.) will undoubtedly increase the difficulty and cost of networking. [0003] The emergence of virtualization technology has rea...
