Problems solved by technology

[0004] At present, distributed virtual switches are not popular in cloud data centers. The common distributed virtual switches are basically vmware and citrix, and both of them need to pay expensive prices to use. For many small and medium-sized enterprises and users, how to build a It is urgent and difficult to implement an inexpensive distributed virtual switching network to meet the increasingly complex network management of cloud data centers
[0005] Software-defined networking (SDN, Software-defined networking) separates the control plane of network equipment from embedded nodes to the software platform, and the network architecture is automatically controlled by the sof

Abstract

The invention provides a method and system for designing a distributed virtual network in a cloud calculating data center. The method and system are applied to the technical field of cloud calculation. The method includes the following steps: creating a distributed virtual switch, wherein the distributed virtual switch is composed of a plurality of OpenFlow virtual switch bodies, an OpenFlow controller and a physical switch port; enabling the OpenFlow virtual switch bodies to be in communication with the OpenFlow controller according to preset strategies. According to the method, the distributed virtual switch is created based on the SDN thought and particularly achieved through the OpenFlow protocol. The whole data center is configured by the distributed virtual switch in a concentrated mode through the OpenFlow controller, virtual switch networking is accordingly simplified, and centralized management and intelligent monitoring on the virtual network environment in the cloud calculating data center are achieved.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a method and system for designing a distributed virtual network of a cloud computing data center. Background technique [0002] The virtual switch is an important software entity in the cloud computing data center, which interconnects the virtual machines, physical hosts and physical network devices in the data center to form a huge virtual resource pool; the virtual switch is responsible for transmitting data to the destination address, detecting The flow of data packets on the network, and the establishment of intelligent connection sessions. [0003] Virtual switches can be divided into standard virtual switches and distributed virtual switches. Their essential difference lies in the scope of their applications: standard virtual switches can only be applied to one physical host without any flexibility, and other hosts cannot share a virtual switch; The distributed vir...
