Facility and Infrastructure: "Accelerating Diverse Data Center Communications by Optics," Yiting Xia, Rice University

Current big data applications have diverse communication patterns [6]. For example, the popular MapReduce computing paradigm shows frequent many-to-one data aggregation and all-to-all data shuffle. Relational join, a typical database operation, requires a "table" to be replicated to all the nodes in a network. Due to massive traffic volumes, these communication patterns lay increasing burden on data center networks. Recent proposals to offload this burden to optical circuit-switched networks [7, 11, 5, 12] provide significant bandwidth increase for stand-alone point-to-point bulk transfers. But they are unable to efficiently support other communication patterns that are crucial to application performance [4]. To address this problem, we propose an unconventional approach that leverages novel physical layer photonics technologies to build customized communication devices for accelerating diverse communication patterns, and integrates such devices into an application-driven, dynamically configurable photonics accelerated data center network. We present preliminary results from a case study to highlight the potential benefits of this approach.
