Fig. 1 is the structural representation of embodiments of the invention;
Fig. 2 is the schematic flow sheet of the application process of embodiments of the invention;
Fig. 3 is embodiments of the invention scheduling flow schematic diagram.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the present invention can combine mutually.
Below with reference to accompanying drawing, embodiments of the invention are done to concrete explaination.
A kind of network USB device Redirectional system of embodiments of the invention as shown in Figure 1.Comprise client 1, service end 2 and wireless network.
Client 1 is provided with client device 3, client application 4 and client and drives 5.Client 1 is provided with USB interface, and client device 3 is connected with client 1 by USB interface.Client device 3 drives 5 to be connected with client application 4 by client.
Service end 2 is provided with virtual unit 6, service end application program 7 and service end and drives 8.Virtual unit 6 drives 8 to be connected with service end application program 7 by service end.Client application 4 is set up data communication by wireless network with service end application program 7 and is connected.
Communication between embodiments of the invention client and service end, all by carrying out between application program, can be avoided the TCP/IP communication of kernel state like this, reduces complexity and improves reliability.
The service end of the client of the preferred windows of scope that embodiments of the invention are realized to windows, the preferred operating system that does not comprise linux operating system or other types.
The scheduling flow schematic diagram of the embodiments of the invention as shown in Fig. 3 is total, the client application of embodiments of the invention needs spare interface, with and other agreement as carried out communication between ICA, RDP, spice agreement, after RDP agreement starts, just can automatically load USB redirection function like this.Need reserved functional module to comprise two contents: with the IP address notification module of service end, client just can be connected on the IP address of service end automatically; Be redirected and select module, determine whether the USB device of some type needs to be redirected.
Communication between the application program of client and driving can adopt the implementation of the ioctl of windows standard.Communication between client application and service end application program adopts TCP/IP connected mode, can adopt third-party link library, also can adopt the winsocket of standard.
In an embodiment of the present invention, client drives and realizes relatively complexity, comprises following content: client virtual bus driver block, the realization of bus driver is a lot, has the implementation of much increasing income.Also need to increase a virtual UPnP administration module energy, after equipment inserts, equipment need to be notified to UPnP administration module, all are normal for the UPnP management function of this equipment.And above realization to be all mode by simulation realize, its virtual bus drives and also needs the content comprising when equipment is pulled out, and clears up all relevant informations, to meet the management regulation of UPnP.
Also needing the content realizing is FDO filter, the PDO filter that loads USB device.Filter function is the characteristic that Microsoft's standard drives, and by filter function, can and forward the Data acquisition transmitting between driving.
In an embodiment of the present invention, service end application program and client application comparing class seemingly, need to load automatically.And the communication modes between its driving adopts the mode of standard ioctl.Accept the various USB events that client-side program sends, and notify bottom layer driving to process; Forward the various requests of bottom layer driving;
Service end drives and is provided with service end emulation bus driver module, accepts the various USB events that client sends.While inserting as USB as shown in Figure 2, driver is done the insertion of a simulation USB device, then enumerates, and the content of enumerating is forwarded to client simultaneously.
Realize after four above-mentioned functional modules, the function of each module is described substantially, and several states of USB device are done to different realizations, as the insertion of USB device, USB device are extracted, the power supply reset of USB device, the dormancy of USB device.Before the insertion of USB device is described, at this, just do not repeat.
