Cloud-BOSS Intra-Data Center Network: on-Demand QoS Guarantees via µs Optical Slot Switching
01 January 2018
Today's traditional, hierarchical, full-electronic data centers are not able to guarantee quality of service (QoS) for latency-sensitive applications nor carrier-grade multitenancy. We propose Cloud Burst Optical-Slot Switching (CBOSS), an intra-data center network architecture leveraging original optical components and custom software-defined network (SDN) control to enable traffic engineering.
In particular, we demonstrate network slicing on demand with sub-wavelength granularity and deterministic per-flow QoS guarantees in a 3-top-of-rack (ToR) Cloud-BOSS network prototype. We rely on a novel integrated silicon photonics (SiP) wavelength dropper, a fast-tunable laser, and custom SDN-based controller.
