Output-buffer switch architecture for asynchronous transfer mode
Hiroshi Suzuki, Hitoshi Nagano, Takamasa Suzuki, T. Takeuchi, Shintaro Iwasaki · 2003
An asynchronous transfer mode (ATM) switch architecture for the broadband integrated services digital network (ISDN) is proposed. The proposed switch, called ATOM switch (ATM output-buffer modular switch), has a multistage network structure, retaining a high degree of modularity for capacity expansion. The ATOM switch element belongs to an output-buffer switch category, and it has a time-division-multiplexed bus and first in, first out buffers for individual outgoing lines. A bit-sliced circuit structure is adopted to implement the high-speed time-division bus and buffer memories. The proposed switch has no throughput degradation because of internal blocking, and has a simple control structure for providing a priority scheme and multicast connections.>
