Problems solved by technology

[0005] The above-mentioned traditional virtual machine detection method has certain limitations due to the need to run software on the terminal. For example, detection cannot be realized in some scenarios where software cannot be installed on the PC, and it is relatively easy to be blocked by anti-detection software

Embodiment Construction

[0036] The present disclosure will be described below with reference to the accompanying drawings. It is to be noted that the following description is merely explanatory and exemplary in nature, and in no way serves as any limitation of the present disclosure, its application or uses. Relative arrangements of components and steps and numerical expressions and numerical values ​​set forth in the embodiments do not limit the scope of the present disclosure unless otherwise specifically stated. Additionally, techniques, methods and devices known to those skilled in the art may not be discussed in detail but are intended to be part of the description where appropriate.

[0037] The inventors found that in the IPv6 network, the host MAC (Medium Access Control, Media Access Control) address, which is information related to the host, is introduced into the IP address of the IPv6 terminal, thereby providing the possibility for virtual machine detection. The following embodiments of t...

Abstract

The disclosure relates to a method for identifying a virtual host in an IPv6 network and DPI equipment. The method comprises a step of receiving, copying and forwarding an IPv6 message, a step of extracting the message head of the copied IPv6 message, a step of extracting and sending the interface address of a source IPv6 address of the IPv6 message from the message head, a step of matching a manufacturer code part in the interface address with a characteristic value in a virtual machine virtual network card interface address characteristic value library, and a step of determining that the IPv6 message is sent by the virtual host if the manufacturer code part in the interface address is same with any characteristic value in the interface address characteristic value library, otherwise, determining that the IPv6 message is sent by a physical host. According to the method and the DPI equipment, in the condition of not installing a virtual machine detection program, the type of the host which sends the message can be identified.

Description

technical field [0001] The present disclosure relates to an IPv6 network, in particular, to a method for identifying a virtual host in an IPv6 network and a DPI (Deep Packet Inspection, deep packet inspection) device. Background technique [0002] Virtual machine technology is a relatively popular host virtualization technology at present. Through this technology, a virtual host environment can be simulated on a physical host, so as to realize the purpose of running multiple operating systems on one host. Currently commonly used virtual machine software includes Vmware, VirtualBox, etc. [0003] Through virtual machine technology, users can simulate a physical host environment on the currently used host, and use this virtual host to surf the Internet. Currently, there are various packet analysis requirements in the network, and the network side needs to be able to identify the virtual machines on the terminal side, for example, 1-to-N detection. [0004] The traditional me...
