In this talk, I'll describe our recent works on design of reconfigurable wireless architectures based on free-space optical (FSO) communication links, and briefly discuss other works on spectrum monitoring and patrolling.
Abstract:
First, I'll describe a datacenter network architecture (called FireFly) based on FSO links that pushes datacenter network design to the extreme on three key fronts: (1) all links are reconfigurable; (2) all links are wireless (FSO); and (3) core (non top-of-rack) switches are eliminated altogether. I'll describe our recent results that demonstrate the viability of this architecture by building a proof-of-concept hardware (link) prototypes and addressing network design and management challenges. Second, I'll describe our recent work on FSO-based wireless backhaul for picocell (small cell) network. Here, to overcome the outdoor effects, we create an architecture (called FSONet) that relies on use of many robust short-range links. I'll describe our architecture and discuss various network design and management issues that arise. Finally, I'll briefly describe my other research interests in spectrum monitoring and patrolling.
