QUARTZ [PDF]

open access: yesProceedings of the 2014 ACM conference on SIGCOMM, 2014
Most datacenter network (DCN) designs focus on maximizing bisection bandwidth rather than minimizing server-to-server latency. We explore architectural approaches to building low-latency DCNs and introduce Quartz, a design element consisting of a full mesh of switches.
