Abstract
The invention provides a port mapping method and a port mapping system under a wide area network (WAN) environment. The port mapping method comprises steps that a, peripheral is inserted into a client side, and device information is encapsulated on a software service side and transmitted to a gateway; b, the gateway receives the device information transmitted by the client side and transmits the device information after being processed to a virtual desktop; and c, the virtual desktop receives the device information, loads a device drive, decompresses the device information and restores the device, so that the device mapping is successful. Due to the adoption of the port mapping method and the port mapping system under the WAN environment, through the principle that the peripheral transmission is analyzed under a traditional way, for the access of a peripheral device under the WAN environment, signal cheat is carried out for the device by utilizing an access gateway technology, the response time of the peripheral device is prolonged, the peripheral control information is cheated, and the peripheral access under the WAN situation is completed. Therefore, an effect for accessing the peripheral device under the WAN environment by utilizing a way for accessing the local peripheral device through a physical personal computer (PC) can be realized.

Background technology
Server virtualization, desktop virtual and applying virtualization are three big Intel Virtualization Technologies in now computer virtualized.It also is an important technology of following cloud computing.At present, begun the popularization of virtualized technology at the industry-by-industry in the whole world, and in the IT industry, coming into one's own gradually.Present global numerous enterprises is all virtual, and gradually virtual fully, develops towards the direction of cloud computing.
Applying virtualization is the indispensable part of cloud computing; It separates user's application and terminating machine; Feasible constraint of using detachment system; But because a large amount of uses of peripheral hardware have fettered the fast development of applying virtualization, the peripheral hardware problem that therefore solves applying virtualization has become the most important thing.
Desktop is promptly served (DAAS) and is promptly served for enterprises and individuals user provides various desktops; Cloud computing can provide desktop for user and employee under WAN environment; But be based under the WAN environment, the use of USB peripheral hardware, serial ports peripheral hardware, parallel port peripheral hardware is very undesirable, because the physical characteristic of USB, serial ports and parallel port; The transmission range of restriction peripheral hardware, the peripheral hardware that has hindered under the WAN situation uses.
Summary of the invention
The object of the present invention is to provide a kind of WAN environment lower port mapping method and system, make the user under WAN environment, visit peripheral hardware just as using the physics PC to visit the effect of local peripheral hardware.
The objective of the invention is to realize through following technical scheme.
A kind of WAN environment lower port mapping method comprises step:
A: client is inserted peripheral hardware, and software service end sealed in unit information also sends to gateway;
B: gateway receives the facility information that client is sent, and is transmitted to virtual desktop after handling;
C: virtual desktop receives facility information, and loading equipemtn drives, and decompression apparatus information, reduction apparatus, device map success.
Preferably, step b specifically comprises: whether the gateway judgment device is available to the virtual desktop network, if network is unavailable, then gateway sends deception information and gives client, and transmitting apparatus information is given virtual desktop simultaneously.
Preferably, said deception information is used to show that equipment transmits.
Preferably, said outer USB device, serial equipment or and the jaws equipment of being made as.
A kind of WAN environment lower port mapped system comprises: client, virtual desktop and gateway, and client is through the wide area network IAD, and virtual desktop connects through local area network (LAN) and gateway,
Client is used for sealed in unit information, sends facility information to gateway through network simultaneously;
Gateway is used for handling receiving the facility information that client sends over, and is transmitted to virtual desktop;
Virtual desktop is used for according to the facility information that receives, and loading equipemtn drives, and decompression apparatus information, reduction apparatus.
Preferably, port mapping systems soft ware service end is installed on the said client, said service end is used for sealed in unit information.
Preferably, said gateway also is used for according to network condition, the service end of the port mapping systems soft ware on the client is sent deception information, in order to state transfer equipment.
Preferably, said outer USB device, serial equipment or and the jaws equipment of being made as.
The present invention compared with prior art, a kind of WAN environment lower port mapping method provided by the invention and system are through resolving the principle of peripheral hardware transmission under the traditional approach; Under WAN environment for the visit of peripheral hardware; Through using the IAD technology, carry out the signal deception for equipment, prolong the response time of peripheral hardware; The peripheral access under the WAN situation is accomplished in the control information of deception peripheral hardware.Thereby make the user under WAN environment, visit peripheral hardware just as using the physics PC to visit the effect of local peripheral hardware.

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 shown in Figure 1ly, WAN environment lower port mapped system of the present invention comprises: client, virtual desktop, gateway, and client is through the wide area network IAD, and virtual desktop connects through local area network (LAN) and gateway,
Port mapped system software service end (Server end) is installed on the client; After peripheral hardware (USB, serial ports and jaws equipment) is inserted on the client device; The service end meeting sealed in unit information of port mapping systems soft ware sends facility information to gateway through network simultaneously;
Gateway receives the information that the service end of the port mapping software on the client device sends, and can carry out information processing, carries out " deception " for the service end of the port mapping systems soft ware on the client simultaneously, and states transfer equipment.
Simultaneously, the virtual desktop installing terminal mapped system software client (Client) under the virtual machine, client receives the facility information that gateway forwards is come, and loading equipemtn drives decompression apparatus information, reduction apparatus.
See also shown in Figure 2ly, WAN environment lower port mapping method of the present invention comprises:
Step 201: client is inserted peripheral hardware, and software service end sealed in unit information also sends to gateway.
Step 202: gateway receives the facility information that client is sent, and is transmitted to virtual desktop after handling.
At first whether gateway meeting judgment device is available to the virtual desktop network, if network is unavailable, then gateway sends deception information " discovering device " and gives client, and transmitting apparatus information is to virtual desktop simultaneously.
Step 203: virtual desktop receives facility information, and loading equipemtn drives, and decompression apparatus information, reduction apparatus.
Step 204: the device map success, can normally use equipment.
