What is GENI? • GENI is a virtual laboratory for exploring future internets at scale. • GENI creates major opportunities to understand, innovate, and transform global networks and their interactions with society. • GENI opens up new areas of research at the frontiers of network science and engineering, and increases the opportunity for significant socio-economic impact. 2 Sponsored by the National Science Foundation IETF-77 – NVRG

GENI Conceptual Design Infrastructure to support at-scale experimentation GENI-enabled at-scale infrastructure Virtualized Deeply programmable Programmable & federated, with end-to- end virtualized “slices” Sensor Network GENI-enabled Federated at-scale International infrastructure Infrastructure Heterogeneous, and evolving over time via spiral development Mobile Wireless Network 3 Edge Site Sponsored by the National Science Foundation IETF-77 – NVRG

Resource discovery Aggregates publish resources, schedules, etc., via clearinghouses What resources can I use? GENI Clearinghouse These Researcher Components Components Components Aggregate A Aggregate B Aggregate C Computer Cluster Backbone Net Metro Wireless 5 Sponsored by the National Science Foundation IETF-77 – NVRG

Slice creation Clearinghouse checks credentials & enforces policy Aggregates allocate resources & create topologies Create my slice GENI Clearinghouse Components Components Components Aggregate A Aggregate B Aggregate C Computer Cluster Backbone Net Metro Wireless 6 Sponsored by the National Science Foundation IETF-77 – NVRG

Experimentation Researcher loads software, debugs, collects measurements Experiment – Install my software, debug, collect data, retry, etc. GENI Clearinghouse Components Components Components Aggregate A Aggregate B Aggregate C Computer Cluster Backbone Net Metro Wireless 7 Sponsored by the National Science Foundation IETF-77 – NVRG

Slice growth & revision Allows successful, long-running experiments to grow larger Make my slice bigger !

Network Virtualization in GENI • GENI uses multiple network virtualization strategies… – Tunnels over IP (GRE, OpenVPN) – Ethernet VLANs (incl QinQ Ethernet tunnels) – OpenFlow (switch forwarding rules based on any header field) • …to connect sliceable computation – Dedicated hosts (e.g., Emulab) – Virtual machines (e.g., PlanetLab, XEN, OpenVZ) – Clouds (e.g., Amazon EC2, Eucalyptus) • …and programmable network devices – Programmable switches (e.g., OpenFlow) – FPGA-based switches & routers (e.g., PEN, SPP, netFPGA) – Virtualizable routers (e.g., Juniper M7i) 13 Sponsored by the National Science Foundation IETF-77 – NVRG

What is stitching? AM AM AM computer computer switch switch switch switch computer computer switch Initially pre-established VLANs or tunnels • “Aggregate managers” orchestrate resource allocation locally • “Stitching” is used to connect aggregates • Establishes linkages among slivers or other entities created by different AMs – The near term emphasis is on Ethernet carriage, i.e., VLANS and tunnels that can carry Ethernet frames – Will want to extend this to other layers – Several stitching approaches are under consideration 14 Sponsored by the National Science Foundation IETF-77 – NVRG
