Abstract
We describe the theory, design and implementation of a 2.5-Gb/s ATM switch growable to very large sizes, say 512×512 (1.28-Tb/s capacity), using a Concentrator-Based Growable Switch Architecture. This architecture is based on a front-end Concentrator-Based Cell Distribution Network followed by fixed-size ATM Output Switches. The front-end concentrator arrangement provides FIFO cell distribution with practical modularity and negligible cell loss. The ATM Output Switches are small-size shared-memory designs that ensure optimal delay-throughput performance for arbitrary traffic patterns. Our prototype consists of a complete and independent 2.5-Gb/s 8×8 ATM switch system with optical 2.4-Gb/s OC-48c and 155-Mb/s OC-3c interfaces, and also an Expansion Module (half shelf) capable of supporting eight such 8×8 switch systems yielding a total prototype capacity of 160 Gb/s.
