Exploration of FPGA-Based Packet Switches for Rack-Scale Computers on a Board

Abstract

This work explores the design space (bandwidthand port configuration) for an FPGA-based top-of-rack switchand, use our implementation, to provide an insight on which ofthese options is the best. We also propose an architecture fora rack-scale computer built on a printed circuit board (PCB) exploiting the FPGA-based switch.
