Abstract

See full text

An ATM (asynchronous transfer mode) cell broadcasting system for use in ATM switches comprises switch matrices for exchanging ATM cells inputted from a plurality of input highways and outputting them to a plurality of output highways. The ATM cell broadcasting system further includes tag information adders, provided at respective input terminals of the switch matrices, for adding tag information according to respective identifiers assigned to the ATM cells. Alternatively, ATM-cell-switching identifier determinant memories may be provided for respective switch elements in the switch matrices, for storing determinant data enabling the switch elements to determine, from the identifiers of the ATM cells, which ones of the ATM cells are to switch and output to their respective output highways.
