The effect of different high-volume traffic on big data applications impose stringent requirements on networks. We investigate drawbacks of segregating big data and elephant flows and propose ways to address the problem using optical network.
A converged optical-wireless testbed is formed integrating TSON sub-wavelength networking in UK and the NITOS wireless solution in Greece. End-to-end service provisioning and flow differentiation are demonstrated across two networks communicating over the GEANT.
Software-defined networking (SDN) enables programmable SDN control and management functions at a number of layers, allowing applications to control network resources or information across different technology domains, e.g., Ethernet, wireless, and optical. Current cloud-based services are pushing networks to new boundaries by deploying cutting edge optical technologies to provide scalable and flexible...
A novel software-defined packet over optical networks solution based on the OpenFlow and GMPLS control plane integration is demonstrated. The proposed architecture, experimental setup, and average flow setup time for different optical flows is reported.
