2. Sponsored by the National Science Foundation 2 Project Summary Deploy five experimental overlay hosting platforms –located at Internet 2 PoPs –compatible with PlanetLab, moving to GENI control framework –performance characteristics suitable for service deployment integrated system architecture with multiple server blades shared NP-based server blades for fast-path packet processing Demonstrate multiple applications Provide ongoing operational support for deployed systems Support development of a user community and provide ongoing support for user experiments –including development of new fastpath code options in partnership with users 8/30/2010

5. Sponsored by the National Science Foundation 5 Accomplishments 1: Advancing GENI Spiral 2 Goals Support for continuous experimentation –deep programmability of SPPs for both the control and data planes of experimental nets –support for slicing – includes slicing of NP resources for high performance data planes –demonstrations to highlight SPP capabilities and refine our understanding of how they can best be used –user tutorials seek to build a user community and foster feedback that can guide future development Support for measurement –SPPs provide support for real-time monitoring of running applications, revealing what happens ”under the covers” – essential for debugging and effective demonstrations –support researcher-driven data collection Support for interoperability –broadly interoperable at the data plane – can support experiments that span PlanetLab, Vini, Emulab, ProtoGENI, Amazon EC2 and generally any internet-based device –construction of applications that span multiple testbeds does require interacting with multiple control mechanism – added time and effort is small fraction of that needed to construct application 8/30/2010

6. Sponsored by the National Science Foundation 6 Accomplishments 2: Other Project Accomplishments Demonstrating potential for Internet-scale overlay hosting –while prototype is quite small, it is architected for scalability –multiple components communicating through a high performance switching layer –generic data plane interface which is broadly interoperable and hides internal details –unified control interface, which hides internal structure from applications and external control elements –support for effective traffic isolation and advance resource reservation Such scalability is essential to a future “Version 1” of GENI –objectives include support for >100K real users running advanced applications over networks supported by GENI infrastructure –will need backbone nodes with IO bandwidths of at least 50-100 Gb/s and 50-100 processing components –will need better support for scalable overlay routers that use many processing components at each site 8/30/2010

7. Sponsored by the National Science Foundation 7 Plans Plans for the remainder of Spiral 2 –improve operational stability of SPPs –prepare demonstrations and tutorial for GEC9 –deploy remaining nodes in Atlanta and Houston Plans for last year of project –support ongoing operation of SPP nodes –continue to build user community through demos and tutorials at GECs 9, 10 and 11 –continue to add material to the SPP wiki pages –work with users on new NPE code options –complete development of flow monitoring subsystem to prevent abuse of SPPs –complete and deploy version 2 of the NPE fastpath software – support for 10 Gb/s operation and multicast packet forwarding Things we still hope to accomplish –multi-node resource reservation –integration of testbed control with GENI control framework –transfer operational control to GMOC –develop control software to support NetFPGAs 8/30/2010

8. Sponsored by the National Science Foundation 8 Issues/Concerns Internet 2 pullback of support for the backbone –undermines our core objective of demonstrating internet-scale overlays –and raises doubts about the credibility of the whole GENI enterprise Lack of engagement of GPO on a technical level –have yet to have a GPO staff member ask a technical question about the SPPs that reflects an informed understanding –no GPO staff member has attended an SPP tutorial, asked for an account or tried to use the SPPs for a simple experiment Uncertainty over future of GENI –hard to avoid feeling that we’re just going through motions until the funding runs out –does GENI have a real future? should it? What is being done to attract application developers to GENI? –internet-scale activities require real users, not just networking researchers –users are attracted by applications, not networking technicalities –need more emphasis on network services that enable new apps, not just low level performance refinements 8/30/2010
