Abstract: We have studied coarse granular routing elaslic optical network that is based on our recently developed coarse granular OXC architecture. The network can exploit both elastic optical networking and coarse granular routing technologies to cope with the trade-off between the link cost and the node cost in order to build a spectrum-and-cost efficient solution for future Internet backbone networks. Firstly, we have introduced our developed coarse granular optical cross-connect (OXC) architecture that enables routing bandwidth-flexible lighlpaths coarse-granularly. We, then, evaluated the hardware scale requirement and the spectrum utilization efficiency of the network with typical modulation formats under various network and traffic conditions. Finally, numerical evaluation was used to verify the spectrum utilization efficiency of the coarse granular routing elastic optical network in comparison with that of conventional WDM network and traditional elastic optical network.
