POPI: A Passive Optical Pod Interconnect for high performance data centers

Abstract : We propose an original approach for realizing an all-optical data center interconnect. This consists in interconnecting racks of servers by WDM channels via an optical coupler and applying an EPONlike dynamic bandwidth allocation (DBA) algorithm. We apply this approach to design a switch-free, podsized data center interconnect that we call POPI for Passive Optical Pod Interconnect. Bandwidth sharing is realized by a central controller that implements an original MAC protocol and DBA algorithm. We evaluate latency and throughput performance, accounting for the dynamic, stochastic nature of data center traffic.
