Description
Technical field
The present invention relates to X11 (X Window System Protocol Version 11, X windows system version 11) agreement, relate in particular to the method and system that realize that the X11 client is connected with the X11 server.
Background technology
X Window System (X windows system) is a cover windows system; Be the exploitation of Unix type operating system by MIT (Massachusetts Institute of Technology) at first; Be widely used in the operating systems such as Linux, Unix, BSD now, the Windows of X windows system and Microsoft has very big difference, and the windows system of Microsoft is by building in the operating system; And the X windows system can't help to build in the operating system; It is common software systems, and various types of Unix operating system can utilize it to realize the operation of graphical interfaces, such as mouse action; Linux or Unix do not have it can move yet, and just can't support the program of graphical interfaces output.The X windows system has obtained very big development since issue, outside the core protocol of X11, increased a lot of Extended Protocols again, and these Extended Protocols and core protocol have made things convenient for the Application and Development of people to X11 together.
The X windows system is based on C/S (Client/Server; Client/server) pattern; Various X11 application programs all are the X clients, the server that has X.org and XFree86 to issue that the X server is now general, about the content of X windows system like " The X Window System "; Software:Practiceand Experience is described in 1990.
Window between the X11 server is shared an application that is based on X windows system C/S model, and this application realizes that to the effect that same window is shared between different X11 servers; Share here and refer to that certain window is shown by a plurality of X11 servers.The sharing mode of current proposition has a variety of, but from essence, has two kinds, and a kind of is through the method that window duplicates the window on the X11 server to be copied on another X11 server; Another kind is through the method for window migration the window on the X11 server to be moved on another X11 server; About the content of window sharing mode like " Collaborative sharing of windows between Mac OS X, the X WindowSystem and Windows ", In Proceedings of Norsk Informatikkonferanse; NIK 2004.Stavanger; Norway, November 2004, described in.
Some agreements and software have been arranged now through realizing between the different X11 servers that window or desktop share inserting a server between X11 server and the X11 client, like VNC and XMove, about VNC and XMove like " Virtual Network Computing "; IEEE INTERNETCOMPUTING; 1998 with " XMOVE:A PSEUDOSERVER FOR X WINDOW MOVEMENT ", TheX Resource, Issue 11; Pp.143-170, July 1994 is said.VNC is an application shared agreement of desktop more widely, and XMove software can be realized the window migration between the X11 server, and what the VNC agreement realized is sharing of whole desktop, and the XMove realization is the migration of single window between the X11 server.Though the function that VNC and XMove realize is different, the method that their are realized is identical in itself, all is to be sent to other X11 servers with the form of compressed picture and to realize sharing through the frame on the local X11 server being cushioned (framebuffer).With frame buffer compression picture is the defective that the realization of technical foundation can exist this technology self can't overcome, and at first is the pressure to the network bandwidth, if application window changes than very fast, will cause program feature to descend rapidly, responds slack-off; Next is that the X11 number of servers of sharing window is had restriction, and a plurality of X11 servers just need send a plurality of frame buffering pictures simultaneously, and this moment, the network bandwidth will become bottleneck.
In the prior art, be connected in case the X11 server breaks off with the X11 client, the X11 client will be out of service.This will be unfavorable to the long playing X11 application program of needs; Because the window that these X11 application programs generate can not be closed, must one heading straight for, in case close; Be equivalent to break off being connected of X11 server and X11 client, will cause application program out of service.VNC does not break off being connected of X11 application program and X11 server with Xmove; Just the framebuffer of X11 server end is sent on another X11 server with the form of picture and show, and actual X11 client still is connected with the X11 server that connects at first.
