Remote collaboration and network-aware applications are the new "commodity" for research and education networks. Each day, more users require services from static or dynamic inter-domain L2VPNs to inter-continental L3VPNs. To enhance its capabilities in supporting multiple network-aware applications, the AmLight network was migrated to an SDN approach in mid-2014. Since then, multiple network applications used the virtualization services offered by the SDN stack deployed. All these applications are being evaluated in parallel with traditional applications, such as HTTP, adding more operational complexity. Migrating to SDN also brought a few challenges, from troubleshooting methodologies to new skills required. In this presentation, AmLight will provide an overview of its migration to an SDN approach, and describe its experience using ONOS/SDN-IP.
