Description
Technical field
Redirected the present invention relates to application distribution technology field, more particularly to a kind of vision facilities based on desktop virtualization
Method and system.
Background technology
Current whole world industry-by-industry all starts to carry out the application of virtualization, and virtualization can store for carrying out server,
Network, the integration of multipad, following development will rise to cloud computing.And it is the basis for carrying out cloud computing to virtualize.
Desktop virtualization is that server virtualization is carried out on the server of data center, generates substantial amounts of independent desktop operating system
(virtual machine or virtual desktop), while being sent to terminal device according to proprietary virtual desktop agreement.User terminal by with
Too net is logged on fictitious host computer, it is only necessary to remember username and password and gateway information, you can pass through network anywhere or anytime
Access the desktop system of oneself.And in desktop virtualization in use, occurring in that making for great amount of images equipment (such as imaging first-class)
Use demand.
The advantage of virtualization promotes virtualization constantly to capture PC markets, but virtualizes and technically still have defect.
Peripheral apparatus (serial paralled interface equipment, USB that desktop virtualization to use on the subscriber terminal by the remote access mechanism of network
Equipment, printer etc.) it can not use, port redirection technology is occurred as soon as, by the serial paralled interface on user local terminal, USB
Port redirection is into the virtual desktop of distal end.But need big data quantity access peripheral apparatus (such as high-definition camera is first-class
Vision facilities) use on, occurred as soon as many problems.Because it is real-time that all data of port redirection technology are dependent on network
Transmission, so network quality just determines the availability and use quality of peripheral hardware, once there is delay, shake, packet loss etc. in network
Phenomenon, vision facilities is just unavailable.So as to can not ensure in user's use can continuity.
