Abstract

Today’s traditional, hierarchical, full-electronic data centers cannot guarantee quality of service (QoS) for latency-sensitive applications or carrier-grade multitenancy. We propose cloud burst optical-slot switching (CBOSS), an intra-data center network architecture leveraging the original optical components and custom software-defined network (SDN) control to enable traffic engineering. In particular, we demonstrate network slicing on demand with subwavelength granularity and deterministic per-flow QoS guarantees in a 3-top-of-rack (ToR) CBOSS network prototype. We rely on an integrated silicon photonics (SiP) wavelength dropper, a fast-tunable laser, and custom SDN-based controller.
