1. a data transmission method is characterized in that, described method realizes that based on main storage buffer and kernel described main storage buffer comprises at least two buffer stoppers, and each buffer stopper disposes the indication information of this buffer stopper of indication, and described method comprises the steps:

  • First communication party obtains the indication information of at least one free buffer piece from described kernel;

    Described free buffer piece is converted into first communication party takies buffer stopper, and described indication information is converted into first communication party'"'"'s occupied state buffer stopper indication information;

    Described first communication party writes described first communication party according to described first communication party'"'"'s occupied state buffer stopper indication information with data and takies buffer stopper;

    Described first communication party who is written into data is taken buffer stopper be converted into kernel and take buffer stopper, and described first communication party'"'"'s occupied state buffer stopper indication information is converted into kernel occupied state buffer stopper indication information;

    Kernel obtains described kernel occupied state buffer stopper indication information;

    Described kernel is taken buffer stopper be converted into second communication side and take buffer stopper, and described kernel occupied state buffer stopper indication information is converted into second communication side takies the buffer stopper indication information;

    Described second communication root takies the buffer stopper indication information according to described second communication side and takies from described second communication side and read described data the buffer stopper, whereinIn described first communication party and the second communication side, wherein a side is peripherals, and the opposing party is user program.
