| | 9 | At GEC10 there was a community discussion of how to talk in a common language about resources. For example, without a common way to |
| | 10 | describe what resources an aggregate provides, it is much harder for experimenters to reason about which resources to use. |
| | 11 | |
| | 12 | Ilia Baldine of RENCI and the Orca control framework proposed a 'workable path forward'. Martin Swany, Jeroen van der Ham, Rob Ricci, Rob Sherwood, Max Ott, Jeff Chase, Andy Bavier, Aaron Falk and others all contributed to a lively debate. Thanks to everyone who has been participating. In the end we agreed to negotiate a common understanding of key concepts, and then use translators to support a single format on the wire as a path forward for GENI. |
| | 13 | |
| | 14 | === Community Agreement === |
| | 15 | The session concluded with community agreement on three points: |
| | 16 | * The community will work to agree on common semantics |
| | 17 | * Ilia has proposals for layer 2 network resources and compute resources, and has recruited community members for other areas; thanks in advance to Max Ott, Hongwei Zhang, Martin Swany, Mike Zink, and Rob Sherwood. These individuals, and others who volunteer to help, will produce ontologies to represent the agreements. |
| | 18 | * GENI will use ProtoGENI RSpec V2 as the format on the wire |
| | 19 | * New concepts will be represented as PG RSpec extensions, allowing free addition and evolution of new concepts as needed. |
| | 20 | * Aggregates can use Translators to convert between formats |
| | 21 | * Ilia is building one between PG and Orca formats. |
| | 22 | |
| | 23 | === Next Steps === |
| | 24 | For all of these, community involvement is key. Email dev@geni.net or Aaron Helsinger (ahelsing at geni.net) to get involved. Results will be published to dev@geni.net and to the GENI wiki to keep everyone informed of progress. |
| | 25 | ==== Agree on Concepts ==== |
| | 26 | * Align edge compute resource concepts, starting with Ilia's proposal. |
| | 27 | * 4 key semantic extensions |
| | 28 | * Wireless (Max Ott, Hongwei Zhang) |
| | 29 | * Measurement (Martin Swany) |
| | 30 | * Storage - physical & cloud (Mike Zink) |
| | 31 | * !OpenFlow flowspace (Rob Sherwood) |
| | 32 | * Produce ontologies for possible ratification at GEC11 |
| | 33 | * The same groups will produce and present these agreements |
| | 34 | |
| | 35 | ==== Adopt Schemas ==== |
| | 36 | * Once the semantics of these things are agreed to, Jon Duerig, Ilia and the GPO will assist in representing these as PG extensions |
| | 37 | * Revisit PG schemas |
| | 38 | * Change more attributes to be elements as needed |
| | 39 | * Make some types less opaque as needed |
| | 40 | * Ensure base is extensible for the known needed extensions |
| | 41 | * Jon Duerig of ProtoGENI will handle this |
| | 42 | * Once adopted, RSpec schemas will be maintained by the community, along with the AM API. |
| | 43 | * Modify the AM API specification to require that RSpecs are in the PG RSpec V2 format |
| | 44 | * Aaron Helsinger and the GPO will handle this, when the support infrastructure is in place |
| | 45 | ==== Implement Translators ==== |
| | 46 | * Write and deploy translators as necessary (coordinate with Ilia for a start - ibaldin at renci.org) |
| | 47 | * Enable conversion as a GENI-wide service |
| | 48 | * Replicating Ilia's converter as necessary |
| | 49 | * Test full PG/Orca interoperability by GEC11 |
| | 50 | * Build a thin PL/PG translation layer at PL (Andy Bavier, Tony Mack, Jon Duerig) |
| | 51 | * Other translators as necessary |
