Wavelength routing based on arrayed waveguide grating (AWG) devices has been proposed as a disruptive technology for capacity, footprint, and flexibility requirements of cloud data centers. The limited buffering capacity of AWG-based routers, however, affects network throughput and makes them highly susceptible to data center traffic imbalance. A load… CONTINUE READING
