Embodiment Construction

[0035] Below with reference to accompanying drawing, the present invention is further described by specific embodiment:

[0036] The scheme of the present invention mainly includes: VNC console proxy, SSH tunnel encryption, double mouse elimination, and virtual desktop monitoring.

[0037] Among them, the VNC console agent is the realization basis of this solution. The so-called VNC console proxy is an intermediate proxy that is specially responsible for forwarding data packets of the virtual machine VNC console. Such as figure 1 , one end of the agent is connected to the management network, and the other end is connected to the business network (Note: the management network is the network environment where the servers in the computer room are located, and the business network is the network environment where the virtual machine tenants are located. The business network and the management network can choose interworking or physical isolate both ways).

[0038] With such a ...

Abstract

The invention discloses a VNC console optimization scheme of virtual machines in a cloud computing environment. VNC console proxy and an SSH encryption tunnel are established, encryption, forwarding and shunting are carried out on VNC data packets, a virtual machine console is used in a multi-network environment, double-mouse phenomena are eliminated by writing an Applet program, the function of virtual machine console monitoring is added, wide-to-height proportions of desktops of the virtual machines are zoomed by means of a graphic algorithm, the desktops of the multiple virtual machines are monitored in the same view, and a administer of a cloud data center is helped to monitor use situations of the virtual machines. Existing VNC source codes are optimized and can be well applied to the cloud computing environment, the console optimization scheme is suitable for the multi-network environment, VNC safety is improved, using characteristics of the VNC console desktops are further optimized, and the function for monitoring the desktops of the virtual machines is enriched.

Description

technical field [0001] The invention relates to the field of cloud data center application systems, in particular to a cross-network, low-bandwidth, high-security virtual machine VNC console optimization scheme. technical background [0002] With the development of information technology, cloud computing has gradually become a hot spot in the industry, and cloud computing service platforms of major manufacturers at home and abroad have also begun to invest in science, education, culture, health, government, high-performance computing, e-commerce, and the Internet of Things. used in many fields. [0003] The virtual machines in the server in the cloud computing environment cannot directly use the display to connect to the desktop, and most of them use VNC for remote connection. VNC (Virtual Network Computing) is a screen sharing and remote operation software using the RFB protocol. The VNC software is connected to the specific VNC port of the server through the network to t...
