Virtual network management method and system for hybrid nested architecture of virtual machine and container

Abstract

The invention provides a virtual network management method and a virtual network management system for a fixed nested framework of a virtual machine and a container, and relates to the fields of cloudcomputing and computer networks. The virtual machine and the container are equally treated, united network management of the virtual machine and container is achieved, a horizontal hybrid deploymentscene of the virtual machine and the container is supported, and meanwhile, the container is also supported to be nested and run in a vertical hybrid deployment scene in the virtual machine. In addition, the method and the system synthesize advantages of concentrated and distributed controllers, a two-stage controller structure is used, the part of functions of a control plane are sunk to a localcontroller on a hypervisor server, the concentrated controller is responsible for overall data maintenance and a third-party operation and management platform interface, the local controller is responsible for flow table maintenance on a local virtual machine switch, the pressure of the overall concentrated controller can be effectively reduced, and the performance of virtual network management can be enhanced.

Description

technical field [0001] The present invention relates to the fields of cloud computing and computer network, in particular to a virtual network management method of a hybrid nested architecture of a virtual machine and a container. Background technique [0002] Virtual machine-based virtualization and container-based virtualization are two typical server virtualization technologies in the field of cloud computing. Decoupling, and the advantages of the latter lie in the lightweight virtualization platform, the convenience of business deployment, and the efficient elastic scaling of resources. coexist. [0003] For virtual machines, the most popular virtual network solution is the neutron solution of openstack. The control plane is realized by the neutron server service on the control node, and the virtual network management of the data plane is realized by the agent on each computing node. Ovsagent implements ovs bridge (br-int, br-eth, br-tun, etc.) flow table management. T...

Problems solved by technology

[0003] For virtual machines, the most popular virtual network solution is the neutron solution of openstack. The control plane is realized by the neutron server service on the control node, and the virtual network management of the data plane is realized by the agent on each computing node. Ovsagent implements ovs bridge (br-int, br-eth, br-tun, etc.) flow table management. The defects of this method include: 1) Centralized virtual network management leads to low performance and is not suitable for fast elastic scaling of container networks ;2) Virtualization scenarios where virtual machines and containers are nested are not supported

[0005] Since virtual machine technology and container technology are two technical routes developed independently, and their virtual network implementation methods also evolve independently, it is difficult to meet the scenarios of virtualization and container hybrid deployment, especially nested deployment. Therefore, a new set is needed. Network management method to provide unified network management capabilities for virtual machines and containers
