We introduce the real-time multitechnology transport layer monitoring to facilitate the coordinated virtualisation of optical and Ethernet networks supported by optical virtualise-able transceivers (V-BVT). A monitoring and network resource configuration scheme is proposed to include the hardware monitoring in both Ethernet and Optical layers. The scheme depicts the data and control interactions among multiple network layers under the software defined network background, as well as the application that analyses the monitored data obtained from the database. We also present a reconfiguration algorithm to adaptively modify the composition of virtual optical networks based on two criteria. The proposed monitoring scheme is experimentally demonstrated with OpenFlow extensions for a holistic (re)configuration across both layers in Ethernet switches and V-BVTs.
