Network Topology

The OpenFlow SDN network topology is composed of Dell Z9100, Mellanox SN2700 and Inventec switches, providing a multitude of 100GE ports with a total switching capacity of above 10Tbps (full duplex). These switches support Openflow 1.0 and 1.3 and are compliant with the latest version of OpenDaylight (ODL) Beryllium controller. Arista 7280R switch-router with deep buffer was used to SCinet for WAN handoff.
