This item was taken from the IEEE Periodical ' ARIS (ATM ring switch): an ATM switch with multicasting capability ' ATM (Asynchronous Transfer Mode) is considered to be the most suitable for broadband integrated networks, because of its time transparency and bandwidth flexibility. Most of the ATM switch architectures proposed are space division type and based on multistage interconnection networks. In this paper, a shared media type of ATM switch architecture is proposed. An important feature of this architecture Is the complete separation of control and data transfer phase. The control information to route the cell internal to switch fabric, is transmitted prior to cell transmission in a pipelined fashion. This helps high speed transmission of data without any header processing bottleneck at the output port The performance of the switch is similar to that of complete output buffer switch. A simple and efficient scheme is proposed to implement broadcasting and multicasting feature without any cell duplication at the input of the switch fabric.
