摘要：
A method and system for implementing zero copy transmission of streaming media data are disclosed in the present invention, and the method and system are based on Linux network protocol stack. The method comprises: when a streaming media server receives a data request from a user equipment, it performs a system call of data transmission, reading the streaming media data out from the disk space and writing it into a user data buffer; packaging the streaming media data stored in the user data buffer as real-time transmission protocol packets which are transmitted applying streaming media packets whose head and load are separated. The method and system of the present invention sufficiently use the DMA function and SG (Scatter/Gather) function of a network card to implement zero-copy transmission of the streaming media data.
