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.

Technical field
The present invention relates to desktop virtual field, particularly relate to a kind of WAN environment lower port mapping method and system.
Background technology
Server virtualization, desktop virtual and applying virtual be now computer virtualized in three large Intel Virtualization Technologies.Also be an important technology of following cloud computing.Industry-by-industry at present in the whole world, has started the popularization of virtualized technology, and coming into one's own in IT industry gradually.Current global numerous enterprises is all virtual, and Full-virtualization gradually, towards the future development of cloud computing.
Applying virtual is an indispensable part for cloud computing, the application of user and terminating machine are separated by it, make the constraint of applying detachment system, but due to a large amount of uses of peripheral hardware, fettered the fast development of applying virtual, the peripheral hardware problem therefore solving applying virtual has become the most important thing.
Namely desktop serves (DAAS) for enterprises and individuals user provides, and namely various desktop serves, under WAN environment, cloud computing can provide desktop for user and employee, but based under WAN environment, the use of USB peripheral hardware, serial ports peripheral hardware, parallel port peripheral hardware is very undesirable, due to the physical characteristic of USB, serial ports and parallel port, the transmission range of restriction peripheral hardware, the peripheral hardware hindered in the wan case 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 user under WAN environment, access the effect of peripheral hardware just as local peripheral hardware accessed by use physics PC.
The object of the invention is to be achieved through the following technical solutions.
A kind of WAN environment lower port mapping method, comprises step:
A: client inserts peripheral hardware, and software service end sealed in unit information also sends to gateway;
B: gateway receives the facility information that client sends, and is transmitted to virtual desktop after row relax of going forward side by side;
C: virtual desktop receives facility information, loading equipemtn drives, and decompression apparatus information, reduction apparatus, device map success.
Preferably, step b specifically comprises: whether gateway judgment device can be used to virtual desktop network, if network is unavailable, then gateway sends deception information to client, and transmitting apparatus information is to virtual desktop simultaneously.
Preferably, described deception information is used for showing that equipment transmits.
Preferably, describedly outer USB device, serial equipment or and jaws equipment is set to.
A kind of WAN environment lower port mapped system, comprising: client, virtual desktop and gateway, client is by wide area network IAD, and virtual desktop is connected by local area network (LAN) and gateway,
Client is used for sealed in unit information, sends facility information to gateway by network simultaneously;
Gateway is used for processing receiving the facility information that client sends over, and is transmitted to virtual desktop;
Virtual desktop is used for the facility information according to receiving, and loading equipemtn drives, and decompression apparatus information, reduction apparatus.
Preferably, described client is provided with port mapping systems soft ware service end, described service end is used for sealed in unit information.
Preferably, described gateway also for according to network condition, sends deception information, in order to state transfer equipment to the service end of the port mapping systems soft ware in client.
Preferably, describedly outer USB device, serial equipment or and jaws equipment is set to.
The present invention compared with prior art, a kind of WAN environment lower port mapping method provided by the invention and system, by the principle of peripheral hardware transmission under parsing traditional approach, for the access of peripheral hardware under WAN environment, by using IAD technology, signal deception being carried out for equipment, extending the response time of peripheral hardware, the control information of deception peripheral hardware, completes peripheral access in the wan case.Thus make user under WAN environment, access the effect of peripheral hardware just as local peripheral hardware accessed by use physics PC.

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 shown in Fig. 1, WAN environment lower port mapped system of the present invention, comprising: client, virtual desktop, gateway, and client is by wide area network IAD, and virtual desktop is connected by local area network (LAN) and gateway,
Client is installed port mapped system software service end (Server end), when peripheral hardware (USB, serial ports jaws equipment) is inserted into after on client device, the service end meeting sealed in unit information of port mapping systems soft ware, sends facility information to gateway by network simultaneously;
The information that the service end of the port mapping software that gateway receives on client device sends, can carry out information processing, carries out " deception " simultaneously, and state transfer equipment for the service end of the port mapping systems soft ware in client.
Meanwhile, virtual desktop installing terminal mapped system software client (Client) under virtual machine, client receives the facility information that gateway forwards is come, and loading equipemtn drives, decompression apparatus information, reduction apparatus.
Refer to shown in Fig. 2, WAN environment lower port mapping method of the present invention, comprising:
Step 201: client inserts peripheral hardware, and software service end sealed in unit information also sends to gateway.
Step 202: gateway receives the facility information that client sends, and is transmitted to virtual desktop after row relax of going forward side by side.
First whether gateway can judgment device can be used to virtual desktop network, if network is unavailable, then gateway sends deception information " discovering device " to client, and transmitting apparatus information is to virtual desktop simultaneously.
Step 203: virtual desktop receives facility information, loading equipemtn drives, and decompression apparatus information, reduction apparatus.
Step 204: device map success, normally can use equipment.
A kind of WAN environment lower port mapping method provided by the invention and system, by the principle of peripheral hardware transmission under parsing traditional approach, for the access of peripheral hardware under WAN environment, by using IAD technology, signal deception is carried out for equipment, extend the response time of peripheral hardware, the control information of deception peripheral hardware, completes peripheral access in the wan case.Thus make user under WAN environment, access the effect of peripheral hardware just as local peripheral hardware accessed by use physics PC.
