“…In order to flexibly allocate appropriate bandwidth for heterogeneous applications, we propose a wavelength-reconfigurable optical packet and circuit-switched network architecture enabling multi-granular interconnectivity at nanosecond-scale switching speeds. Previous work presented in [15] experimentally demonstrates a photonic switch supporting both packet and circuit switching at the granularity of each port. In this work, we integrate a wavelength selective switch (WSS) into the design of [15], illustrating the potential for supporting hybrid switching functionality at sub-wavelength granularities through dynamic wavelength provisioning.…”

Abstract-The communication requirements imposed by the unabated growth in both the size and computational density of modern data centers will soon outpace the fundamental capabilities of conventional electronic interconnection networks. Optical interconnects represent a potentially disruptive technology that can simultaneously satisfy the throughput, latency, and energy demands of these next-generation systems. In this paper, we propose an end-to-end photonic networking platform for future optically-interconnected data center networks. A reconfigurable hybrid photonic network building block and a protocol-agnostic optical network interface comprise the key elements of our proposed system. A modular optical switch fabric prototyping platform is designed and implemented to support a wide variety of potential photonic technologies. We successfully demonstrate nanosecond-scale optical packet-switching at 1-Tb/s per port (40-Gb/s s) through our prototype, configured as a 4 4 switch, and confirm error-free transmission across all wavelengths. In order to flexibly allocate appropriate bandwidth for heterogeneous applications, we further implement and evaluate a novel wavelength-reconfigurable optical packet-and circuit-switch by utilizing our optical switch platform. Finally, we detail our implementation of an optical network interface card (O-NIC) designed to bridge the gap between the well-established protocol layers utilized in current networks and the physical layer of the proposed photonic networks and demonstrate its functionality by the streaming of high-definition video through the end-to-end optical network.

“…It is also important that the network nodes have the capability to scale to a large number of ports while introducing little latency. It has been recognized that 1 × N optical-packet switches (OPSs) form a key building block for a scalable node [2], showing data format agnostic behavior and scalability to a large number of ports at the expense of low latency [3].…”
