Sponsored by the National Science Foundation 2 February 10, 2010 GENI Aggregate Manager Spiral 2 Goals Allow GENI Aggregates to affiliate with GENI control frameworks through a common API Enable researcher access to conforming GENI Aggregates through two existing control frameworks: PlanetLab and ProtoGENI Integration with other GENI control frameworks will occur in Spiral 3 Implement three kinds of GENI Aggregate Managers: PlanetLab nodes, ProtoGENI clusters and OpenFlow switches Demonstrate a Slice containing PlanetLab, ProtoGENI, and OpenFlow resources at GEC 9

Sponsored by the National Science Foundation 3 February 10, 2010 What is an Aggregate? An aggregate is a set of managed resources (computers, virtual machines, wireless devices, network switches, VLANs, tunnels, etc.) An aggregate affiliates with a control framework An aggregate participates in a web of trust

Sponsored by the National Science Foundation 4 February 10, 2010 What is a Control Framework? A Control Framework consists of a Registry and a Slice Authority Control Frameworks are trust anchors Both PlanetLab and ProtoGENI are examples of GENI Control Frameworks PlanetLab and ProtoGENI Control Frameworks will support GENI Aggregates Spiral 2 Goal: GENI Aggregates will be able to affiliate with either the PlanetLab Control Framework or the ProtoGENI Control Framework or both

A client is a researcher tool A client provides access to a Control Framework, and thus to a set of Aggregates A client helps a researcher configure, start, monitor and stop a slice Example clients include GUSH, sfi, and the ProtoGENI flash client

Sponsored by the National Science Foundation 12 February 10, 2010 Things this API is not addressing RSPECs –The API is intentionally agnostic to RSPECs –This puts extra burden on clients to understand a heterogeneous set Stitching –The API is intentionally agnostic to stitching –The API is intended to allow experimentation with stitching approaches Scheduling –Time is buried in RSPECs –No reservations –Anticipated in a future revision

Sponsored by the National Science Foundation 13 February 10, 2010 Where are we? Draft API published – – Gathering comments and feedback now Implementation phase expected between GEC 7 and GEC 8 Demonstration at GEC 9 News and updates via Control Framework Working Group mailing list

Sponsored by the National Science Foundation 14 February 10, 2010 Summary This is not the final API The API is intentionally minimal This is a starting point for adding required capabilities We expect the API to grow and change over time
