AWG-based Optoelectronic Router with QoS Support

• We present a router architecture with electronic queuing and a passive optical multi-channel network, which is based upon a single-hop star topology with an arrayed waveguide grating (AWG) at its center. The AWG's property of spatial wavelength reuse and both fixed-tuned and tunable transceivers enable simultaneous control and data transmission. Our proposed medium access control protocol supports traffic differentiation and utilizes EOF (earliest deadline first) to schedule the traffic from input ports to output ports on the router. Our simulations show that the router treats QoS (quality of service) traffic well.
