ATM switch capable of detecting addressing errors |
摘要 |
An ATM switch includes a multi-destination delivery number counter. The counter stores a multi-destination delivery number of each inputted cell according to destination information in the cell correlating the multi-destination delivery number with an idle address where the cell is stored, on every writing of a cell into an idle address of the shared buffer, and decrements the multi-destination delivery number of the cell on every reading of the cell from the shared buffer. The multi-destination delivery numbers of the cells are utilized for management of switching output of the cells from the shared buffer. The multi-destination delivery number counter detects addressing errors to the shared buffer according to the multi-destination delivery numbers, on every inputting or outputting of the cells. According to the ATM switch, both miniaturization of circuit scale of the ATM switch and improvement of reliability of the ATM switch are made possible.
