Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
See also Fig. 1, the data transmission system that is applied to virtualized environment in the present embodiment comprises virtual machine and terminal, and is defined as virtual machine assembly and terminal assembly respectively in order to the functional unit of realizing peripheral hardware and port mapping in virtual machine and the terminal.
Wherein, the virtual machine assembly comprises:
Virtual desktop is opened the unit, is used for opening one or more virtual desktop session (present embodiment is only to the situation of opening a plurality of virtual desktop sessions simultaneously);
The virtual desktop switch unit is used to carry out the switching between the different virtual desktop, and produces the desktop handover event.
Wherein, terminal assembly comprises:
Virtual desktop handover event capturing unit is used for the desktop handover event of captured in real time virtual desktop switch unit generation and correctly obtains the target desktop of switching;
Equipment session is set up the unit, is used for when being driven, and sets up the equipment dialogue of target desktop;
The dynamic switch unit of equipment session is used for when virtual desktop handover event capturing unit captures the desktop handover event, and the equipment dialogue that the target desktop is set up in the unit is set up in the driving arrangement session.
In the above-mentioned data transmission system, terminal assembly has been set up virtual desktop handover event capturing function, makes terminal assembly to grasp after correctly and works as the dynamic of front desktop; The dynamic handoff functionality of bonding apparatus session simultaneously goes thereby make equipment session correctly to be adapted in the front desktop session.
In conjunction with Fig. 2 and shown in Figure 3, the method that a plurality of virtual desktop self-adaptations of the realization of above-mentioned data transmission system are switched is:
301, open a plurality of virtual desktop sessions.
302, the front desktop session is worked as in terminal assembly identification, and the apparatus for establishing session is to current virtual desktop.
303, captured in real time is caught the back and is carried out next step at the desktop handover event that the user produces when switching to other desktop sessions when the front desktop session.
304, terminal assembly is caught the session of target desktop, and is promptly next when the front desktop session.
305, terminal assembly is removed the equipment session (equipment that does not use can adopt delay policy) of current virtual desktop, and sets up the equipment session of target desktop, realizes equipment session and the self-adaptation action of working as front desktop.
In this method implementation procedure; In order correctly to use the equipment on all terminating machines under the situation of landing a plurality of virtual desktops at the same time; Must adopt the use-pattern that exclusively enjoys but not share for the peripheral hardware on the terminating machine; Also correctly catch through detecting desktop handover event simultaneously and work as front desktop, the realization equipment session is to the synchronous of the self-adapting type of working as front desktop and guarantee data integrity, finally reaches the purpose of all devices on the correct use terminal.
In actual application; The user may increase or reduce the desktop session as required; Handle through equipment session adaptive mode as shown in Figure 4 this moment: when newly-increased desktop session; Terminal assembly is caught newly-increased desktop session becomes the target desktop, produces the equipment session self-adaptation action that the desktop handover event removes to drive terminal assembly simultaneously; When reducing the desktop session; Terminal assembly is caught its desktop session that closes on as the target desktop after finishing a desktop session; Produce the equipment session self-adaptation action that the desktop handover event removes to drive terminal assembly simultaneously, until last desktop conversation end, equipment session also will really finish.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
