Design of Interconnection Networks

This paper focuses on future trends and challenges in interconnection network design. Historically used only in high-end supercomputers and telecom switches, interconnection networks are now found in systems of all sizes and all types from large supercomputers to small embedded systems-on-a-chip (SoC) and from inter-processor networks to router fabrics. Indeed, as system complexity and integration continues to increase, many designers are finding it more efficient to route packets, not wires.
