Port mapping method and port mapping system under wide area network (WAN) environment

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.

Description

technical field [0001] The invention relates to the field of desktop virtualization, in particular to a port mapping method and system in a WAN environment. Background technique [0002] Server virtualization, desktop virtualization and application virtualization are the three major virtualization technologies in computer virtualization. It is also an important technology for future cloud computing. At present, in various industries around the world, the promotion of virtualization technology has begun, and it is gradually becoming popular in the IT industry. At present, many enterprises around the world have been virtualized, and gradually fully virtualized, developing towards the direction of cloud computing. [0003] Application virtualization is an indispensable part of cloud computing. It separates the user's application from the terminal, making the application out of the constraints of the system. However, due to the extensive use of peripherals, the rapid developme...

Problems solved by technology

[0003] Application virtualization is an indispensable part of cloud computing. It separates the user's application from the terminal, making the application out of the constraints of the system. However, due to the extensive use of peripherals, the rapid development of application virtualization is restricted. Virtualized peripheral issues become a top priority

[0004] Desktop as a service (DAAS) provides a variety of desktop as a service for enterprises and individual users. In the WAN environment, cloud computing can provide desktops for users and employees. However, based on the WAN environment, USB peripherals, serial port peripherals, The use of parallel peripherals is not ideal. Due to the physical characteristics of USB, serial ports and parallel ports, the transmission distance of peripherals is limited, which hinders the use of peripherals in WAN situations.
