Abstract: A method for data communication in a virtualized environment is disclosed as follows. A write function of a graphics driver is called by a graphics processing program using a graphics processing interface, where a function in a call process is recorded in a function stack; an entry address of a write function of the graphics processing interface is determined according to an entry address of the write function of the graphics driver and a quantity of layers of the function stack, and an offset and a length that are of a vertex buffer of the graphics processing program are read from the entry address of the write function of the graphics processing interface, so as to determine a data area that is modified by the graphics processing program and is in the vertex buffer, where the modified data area is data necessary for graphics rendering.

Abstract: A method and an apparatus for sending data in a visual desktop infrastructure (VDI) environment, where the method includes, when a desktop protocol client is in an abnormal state, a desktop protocol server sending desktop image data to the desktop protocol client at a rate lower than a rate used when the desktop protocol client is in a normal state, and when the desktop protocol client is in an abnormal state, the desktop protocol server still sends desktop image data to the desktop protocol client, when the desktop protocol client resumes to a normal state, the amount of data that needs to be sent by the desktop protocol server is greatly reduced as compared with the prior art, therefore, occupied network bandwidth is reduced, and a display delay is reduced, thereby improving user experience.
