TL;DR: OpenVirteX as discussed by the authors is a network virtualization platform that enables operators to create and manage virtual Software Defined Networks (vSDNs), allowing tenants to specify the topology and addressing scheme of their vSDNs, and run their own Network Operating System (NOS) to control it.

TL;DR: In this paper, the authors analyze the connectivity of WDM PONs composed of multiple stages of waveguide grating routers and present a design tool to evaluate the connectivity functions.

TL;DR: In this paper, the authors evaluate the advantages of using the extra dimension introduced by space-division multiplexing (SDM) for dynamic bandwidth-allocation purposes in a flexible optical network, with an emphasis on the spectral efficiency (SE)/reach tradeoff for different multiline-rate scenarios, created either by changing the number of sub-channels (Sb-Ch), or by employing different modulation formats.

TL;DR: Experimental results show that Vertigo can deliver flexible and reliable network virtualization services to a wide range of use cases in spite of failure and/or congestion at the underlying physical network.

TL;DR: The OFELIA testbed as discussed by the authors is a multi-layer, multi-technology and geographically distributed Future Internet testbed facility, where the network itself is precisely controlled and programmed by the experimenter using the emerging OpenFlow technology.
