PROBLEM TO BE SOLVED: To realize a data transmission method which efficiently and flexibly utilizes a buffer memory location where data loss is prevented and an interface can be used at the same time and goes through plural interfaces arranged in parallel. SOLUTION: This method allocates the buffer memory location of a shared buffer memory to a receiver unit 1 when it is initialized, intermediately stores a data packet in the buffer memory location allocated to the receiver unit and further requests a memory location managing part 3 for another buffer memory location, the part 3 further allocates another required buffer memory location to the receiver unit and transmits the buffer memory location to a transmitter unit 2, and the buffer memory location of the data packet is cleared after this data packet transmission. |
