In this paper we propose an analytical model able to analytically evaluate the performance of an asynchronous Optical Packet Switch (OPS) realized in Semiconductor Optical Amplifier (SOA). The considered switch has a bufferless architecture that shares the wavelength converters for input wavelength. The obtained results show how the proposed model is more accurate than others proposed in literature in the case of small size switches. © 2011 IEEE.

In packet-opto scenarios, packet offload towards the optical layer enables transit traffic to avoid packet processing in intermediate nodes saving costs and power. A strategy to dynamically tune the offload level is presented and simulated. © 2013 OSA.

The article proposes a hierarchical routing approach, validated by simulation on real network operator, based on a novel adaptive virtualization scheme, suitable for transport SDN, allowing dynamic configuration of heterogeneous multi-domain packet-optical networks. © OSA 2014.
