Abstract
A detailed examination of evolving traffic characteristics, operator requirements, and network technology trends suggests a move away from non-blocking interconnects in data center networks (DCNs). As a result, recent efforts have advocated oversubscribed networks with the capability to adapt to traffic requirements on demand. In this chapter, we will introduce OSA, a novel optical switching architecture for DCNs. Leveraging runtime reconfigurable optical devices, OSA dynamically changes its topology and link capacities, thus achieving unprecedented flexibility to adapt to dynamic traffic patterns. Implementation and evaluation of a small-scale prototype demonstrate the feasibility of OSA.
