A growable Packet (ATM) Switch Architecture: Design Principles and Applications.

This memorandum focuses on the generic problem of designing a large NxN (N > 1000) high-performance, broadband packet (or ATM) switch. Despite recent advances in switch architectures, practical switch dimensions continue to be severely limited by both the technological and physical constraints of packaging (e.g., chip or board sizes). Here, we focus on switch growability: we provide ways to construct arbitrarily large switches out of modest-size packet switches, without sacrificing overall delay/throughput performance.
