Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1, the data transmission system being 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 realizing peripheral hardware and port mapping in virtual machine and terminal.
Wherein, virtual machine assembly comprises:
Virtual desktop opens unit, for opening one or more virtual desktop session (only for the situation of opening multiple virtual desktop session simultaneously in the present embodiment);
Virtual desktop switch unit, for carrying out the switching between different virtual desktop, and produces desktop handover event.
Wherein, terminal assembly comprises:
Virtual desktop handover event capturing unit, for catching the desktop handover event also correct target desktop obtaining switching that virtual desktop switch unit produces in real time;
Equipment session sets up unit, for when by driving, sets up the equipment dialogue of target desktop;
Equipment session switching at runtime unit, for when virtual desktop handover event capturing unit captures desktop handover event, driving arrangement session establishment unit sets up the equipment dialogue of target desktop.
In above-mentioned data transmission system, terminal assembly has set up virtual desktop handover event capturing function, makes terminal assembly can after correctly grasping the dynamic of current desktop; Simultaneously bonding apparatus session switching at runtime function, thus equipment session can be correctly adapted in current desktop session go.
Shown in composition graphs 2 and Fig. 3, the method realizing the switching of multiple virtual desktop self-adaptation of above-mentioned data transmission system is:
301, multiple virtual desktop session is opened.
302, terminal assembly identification current desktop session, and apparatus for establishing session is to current virtual desktop.
303, be captured in the desktop handover event produced when user is switched to other desktop sessions by current desktop session in real time, catch rear execution next step.
304, terminal assembly target acquisition desktop session, i.e. next current desktop session.
305, terminal assembly removes the equipment session (equipment do not used can adopt delay policy) of current virtual desktop, and sets up the equipment session of target desktop, realizes the self-adaptation action of equipment session and current desktop.
In the method implementation procedure, in order to the equipment on all terminating machines correctly can be used when logging in multiple virtual desktop at the same time, must adopt for the peripheral hardware on terminating machine and exclusively enjoy and unshared use-pattern, also correctly catch current desktop by detecting desktop handover event simultaneously, realizing equipment session to self-adapting type synchronous of current desktop guarantees data integrity, finally reaches the object of all devices in proper use of terminal.
In actual application, user may increase or reduce desktop session as required, now processed by equipment session adaptive mode as shown in Figure 4: when newly-increased desktop session, terminal assembly catches newly-increased desktop session becomes target desktop, produces the equipment session self-adaptation action that desktop handover event removes to drive terminal assembly simultaneously; When reducing desktop session, after terminating a desktop session, terminal assembly catches its desktop session closed on as target desktop, produce the equipment session self-adaptation action that desktop handover event removes to drive terminal assembly, until last desktop conversation end, equipment session also will really terminate simultaneously.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
