Embodiment Construction

[0028] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Such as figure 1 As shown in , it is a schematic diagram of distribution across mirroring peer-to-peer networks in the present invention. In the cross-image peer-to-peer distribution network described in the present invention, all image files are initially stored in the image server Image server. When distributing the virtual machine image to a specific physical host according to the request, the image server Image server is responsible for distributing the virtual machine image to each physical host and coordinating the data exchange between the physical hosts, and the image server Image server is also responsible for storing the active virtual machine request list . When a request for a virtual machine instance arrives at the image server, the image server first selects an appropriate target physical host and genera...

Abstract

The invention relates to the cloud computing field, in particular to a bandwidth optimization method of a virtual mirror server. The bandwidth optimization method comprises the steps of: a mirror server periodically collecting distribution information while distributing a virtual machine mirror to each physical host; and the mirror server adjusting the server bandwidth distribution in the current state according to the distribution information. According to the invention, the bandwidth distribution adjustment to the mirror server is added to a cross-mirror peer-to-peer network distribution network, so that the bandwidth optimization method provided by the invention can realize the optimized overall distribution efficiency by adjusting the distribution bandwidth of the mirror server to a specific mirror file, thereby effectively improving the overall mirror distribution efficiency of the virtual machine and further providing better user experience.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a bandwidth optimization method of a virtual image server. Background technique [0002] Cloud computing effectively reduces users' investment in IT infrastructure and changes the status quo in the computer field. An important feature of cloud computing is that it can quickly and flexibly provide computer resources to users. In the cloud data center, all kinds of resources need to be automatically allocated in a timely manner according to the user's needs at a suitable granularity. Virtualization technology is an effective way to achieve this allocation. Most of today's cloud data centers store and distribute different virtual machine images through a central image server group. These images may be a pure operating system or various software and applications added to the operating system. When receiving a request, the mirroring server mirrors the virtual machines required by dis...
