Session Description

This talk describes recent work with SDN applications and operations in the Global Environment for Network Innovations (GENI), a national-scale US virtual laboratory for networking and distributed systems research and education sponsored by the National Science Foundation. GENI resources include include combinations of processors, storage and programmable switches built into expandable GENI racks, as well as local, regional, and national OpenFlow-based SDN networks. GENI enables a variety of research and operations experiments for both academic and industry participants. Experiments share resources with slices that cross a wide range of technologies and protocols in campus, regional, metropolitan and core network environments. Running applications and operations in a shared SDN environment presents many challenges. Shared operations for this environment is beginning to transition from original developers and systems integrators to production operations and continuing SDN services. This joint presentation combines GENI operations and GENI user perspectives on developing and operating OpenFlow services and transitioning them to production, using Clemson’s GENI Cinema project ( and a student Hadoop/OpenFlow project as examples.
