Abstract

The invention discloses a micro-isolation protection method and system based on an OpenFlow protocol, belongs to the technical field of the Internet, and solves the problems that in the prior art, east-west flow access control is carried out on massive virtual machine networks, bandwidth is consumed for drainage, or loads are generated, and resources are competed with clients. The network communication relationship between the virtual machines is obtained through the obtained continuous flow table. All the virtual machines are divided into a plurality of micro-isolation groups by utilizing animproved MCL algorithm based on a network communication relationship. An isolation strategy for the micro-isolation groups and the virtual machines is generated in the micro-isolation groups accordingto each micro-isolation group. The communication ports necessary for the virtual machines to run the service and the service types predefined by the virtual machines. The invention is used for performing micro-isolation protection on the virtual network constructed by a plurality of VMs in a virtualization environment.

Description

technical field

[0001] A micro-isolation protection method and system based on the OpenFlow protocol are used for micro-isolation protection of a virtual network constructed by multiple VMs in a virtualized environment, and belong to the technical field of the Internet. Background technique

[0002] With the development of virtualization technology, more and more enterprises have changed their original hardware server deployment strategies to adopt data center virtualization solutions. Virtualization technology can turn a physical server into several or even hundreds of virtual hosts isolated from each other, and turn physical resources (such as CPU, memory, magnetic I / O, etc.) into "resource pools" that can be dynamically managed. The demand is dynamically allocated to multiple logical virtual machines, which improves resource utilization and reduces costs, but also brings some new security issues. For example, there is a lack of security isolation between virtual machines...
