For example, if the data temporarily stored in the buffer falls below a given threshold value of the buffer, data is stored in the buffer in FIFO. If the data temporarily stored in the buffer exceeds a given threshold value of the buffer, data is stored in the buffer in FILO. A sending unit outputs data taken from the buffer in FIFO or FILO, to a network. | 03-04-2010 |
