Problems solved by technology
[0012] Although the X protocol is based on the network, it is not fully considered in design and has a large demand for bandwidth. The bandwidth is large inside the machine and in the LAN, and the network delay is small. The disadvantages of the X protocol are not obvious.
However, in the wide area network, the X protocol is not competent
The X protocol itself is not a lightweight remote desktop protocol, and it is not suitable to be directly used as a desktop connection technology in a cloud computing environment.

Embodiment Construction
[0055] In order to make the technology, means and advantages adopted by the present invention, preferred embodiments are given and described in detail below with accompanying drawings, which are for illustration purposes only, and are not limited by this structure in patent application.
[0056] attached figure 2 It is a structural diagram of the optimized X window system of the present invention. Such as figure 2 As shown, both the X client agent module 21 and the X server agent module 22 include a connection module (211 or 221), a preprocessing module (212 or 222), a buffer management module (213 or 223), a compression management module (214 or 224) and codec module (215 or 225). The present invention compresses and optimizes the X protocol message. Although the submodules in the X client proxy module and the X server proxy module are the same, when the direction of the X protocol message flow is different, the X client proxy module and the X server The functions corres...

The invention relates to a remote desktop system and a method for optimizing an X protocol. The system comprises an X client, an X client proxy module, an X server proxy module, an X server and an X desktop monitor; and both the X client proxy module and the X server proxy module comprise a connecting module, a pretreatment module, a buffer management module, a compression management module and a coding and decoding module. The X server proxy module and the X client proxy module are added in an X window system, the present X protocol is compressed and optimized through the X server proxy module and the X client proxy module, programs and codes of an original X window system are unnecessary to change for the optimized X system, the added X server proxy module simulates the X client, the X client proxy module simulates the X server, the X protocol is optimized simultaneously by the X client proxy module and the X server proxy module, so the optimized system is transparent to the present X window system, and a great amount of X weaknesses are eliminated, the repeated transmission of large data can be avoided, and the message polling and the like in the X protocol can be eliminated.
Description
technical field [0001] The invention relates to a remote desktop system and method, in particular to a remote desktop system and method optimized for the X protocol. Background technique [0002] With the development of virtualization and cloud computing, users' demands for efficient remote desktops are increasing. However, traditional remote desktop methods such as VNC and XDMCP have many shortcomings. They do not use data compression, the speed is slow, the image transmission has obvious lag, and generally there is no encryption, and the security is poor. Moreover, the current domestic Internet bandwidth is low, and traditional methods such as VNC cannot meet the basic needs of users. How to provide smooth desktop connections in a low-bandwidth environment has become a bottleneck for the development of cloud computing, especially public clouds. [0003] In the context of insufficient network bandwidth, efficient remote desktop technology has once again attracted people's ...
