Accelerating Collective Communications with Mutual Benefits of Optical Rackless DC and In-Network Computing

We propose a novel architecture to explore the mutual benefits of optical rackless data center (ORDC) and in-network computing for accelerating collective communications. It reduces job completion time of MapReduce clusters by $27.4 \%$ to $43.3 \%$ over traditional ORDC in experiments. OCIS codes: (060.1155) Software-defined optical networks; (060.4251) Networks, assignment and routing algorithms.
