Abstract

The invention discloses a virtual switching method of a cloud computing system. The invention further relates to a system for realizing the method. The system in the invention consists of five parts including a virtual switching subassembly, a virtual interface, an address switching subassembly, a network bridge compatibility subassembly and a monitoring management subassembly. The communication between a virtual machine and an external network is realized by virtual double-layer transmission and address switching; and states and rules of a network interface of the virtual machine can be synchronously shifted when the virtual machine is shifted. The virtual switching system realized in the invention provides efficient double-layer transmission capability and address switching capability so as to solve the problems in the communication between the virtual machine and the external network in a private local area network of the cloud computing system, and the synchronous shift of the states and rules of the network interface of the virtual machine with no need of extra hardware equipment. The invention has the advantages of high usability and low cost.

Description

technical field [0001] The invention relates to a virtualization technology, in particular to a virtual exchange method and system in a cloud computing system. Background technique [0002] Cloud Computing is a business computing model evolved from distributed processing, parallel processing and grid computing. The basic principle of cloud computing is to build a large-scale distributed computing system resource library, distribute system computing in the system resource pool, and consider overall system resource utilization. The cloud computing system can switch resources to the required applications, obtain computing power, storage space and various software services according to the needs, and improve the equipment utilization rate of the entire system. Cloud computing systems all use virtualization technology to virtualize multiple virtual computers (virtual machines, Virtual Machines, VMs) on a physical server, on which multiple independent operating systems can run si...
