Paper Abstract

We propose a new design for a self-routing, space-division fast packet switch for ATM B-ISDN. This is an expansion switch based on binary expansion, concentration, and combination of neighboring blocks of packets. Internal buffers are needed for local synchronization and packet buffering for eventualities of path collision and/or next stage buffer full. An expansion network such as the UDEL switch provides multiple paths for any input/output pair. These multiple paths help to alleviate many common problems including head-of-line (HOL), internal path conflicts, and output collisions. Our proposal provides 10-10 packet drop rate between two stages under random uniform traffic with a unique 3-dimensional arrangement of printed- circuit boards. Batcher-banyans or similar small switches may be used as the last stage.
