    98 At the end of Spiral 2, we are ahead of our goals with respect to the main vision of the project, and have demonstrated real-time reactive use of optical substrate measurements to allow in-slice protocols to react by tuning optical substrate parameters.  A detailed description is available in the GEC8 demo report.  The diagram below shows the essentials of the demo setup.

     105We experimentally demonstrate a video streaming application across BEN. We add cross-layer communication and control capabilities to BEN by integrating it with the SILO service-oriented architecture and a NetFPGA-based optical control plane. Dynamic optical power fluctuations introduced to BEN are either compensated using a semiconductor optical amplifier (SOA) or the lightpath is rerouted to ensure that a video requiring high QoS retains its fidelity. For comparison, a video requiring lower QoS is transmitted without impairment compensation or rerouting and suffers a noticeable degradation in quality. A detailed description is available in the GEC8 demo report. [[BR]]
