Presentation Transcript

  1. The GENI Meta-Operations Center (GMOC) • If it’s research, why do we care about operations?

  2. GENI • Project to Build • Infrastructure to support greenfield network science • NOT Research in itself • The Test Track, not the car

  3. GENI Summary • Funded by NSF • BBN Technologies serves as the GENI Project Office (GPO) • 2 Solicitations so far • Solicitation #1 had 29 funded projects • Solicitation #2 had 33 funded projects

  4. GENI Control Frameworks • GPO grouped projects into control framework clusters • each cluster is anchored by a project to develop a control plane for the facility • 5 clusters initially: • PlanetLab • TIED • ProtoGENI • ORCA/BEN • ORBIT

  5. GENI Early Focus: “Slicing” • In GENI, a slice means a set of virtualized resources connected together to provide a single virtual testbed for a scientist • “slicing” across parts of a control framework cluster is main thrust now • future will mean inter-cluster slicing & federation with other facilities & networks

  6. GENI Meta-Operations Center

  7. What’s “Meta” mean? • GENI is made up of many loosely affiliated projects • Many projects have existing means to provide operations • But what about operating GENI as a whole? What’s needed? • Option 1/NOTHING - each part can operate independently without additional effort for GENI as a whole • Option 2/Central GENI Operations Center - all GENI resources should be centrally managed & operated by a GENI operations center • Option 3/Meta-operations - GENI projects can best handle most operational tasks. For GENI as a whole, someone should coordinate operations across projects to present a single interface to operators and users.

  8. Project C Project D Project B Project A Option 1 - Completely Distributed Cluster 2

  9. Project C Project D Project B Project A Option 2 - Centralized Cluster 1 Cluster 2

  10. Project C Project D Project B Project A Option 3 - Meta-Operations Cluster 1 Cluster 2

  11. GMOC Architecture

  12. GMOC Exchanger - Polls and/or receives operational data from aggregates • GMOC Repository - Central datastore for operational data from all GENI parts • GMOC Translator - Translates information from other formats into consistent data format • Operations - Watches Data to provide useful functions like Emergency Shutdown GENI Meta-Operations Center

  13. Early GMOC Functions

  14. GENI View of Operational Status • Give GENI-wide view of operational status • maps & graphs • prototype other views, such as slice-by-slice views • Give Scientists access to their data • “What was going on during these 2 weeks I ran my test?”

  15. Emergency Stop Emergency Stop • Identify & Shut down Misbehaving Slices • Protect Other Slices • Ensure Stability • in Phase1, Emergency Stop will consist of a process for manual contact of projects • Emergency Stop Demonstration To be performed in 2010

  16. Challenges for GENI Operations

  17. Challenge #1: Federation • GENI has many projects • doing different kinds of things • with different abilities to provide operational data • with different requirements for operational data • GMOC depends on cooperation from them all • Balance between central visibility and decentralized autonomy will need to evolve (and continue evolving)

  18. GENI Aggregates Challenge #2: Layers of Visibility

  19. GENI Components Challenge #2: Layers of Visibility

  20. Challenge #2: Layers of Visibility

  21. Challenge #3: Virtualized Operations • Everything is more temporary • what “slices” are out there (NOW, 3 weeks ago)? • How do we correlate current slices to future slices for repeatability • Everything is more complex • Many different groups to serve: Operators, Researchers, “Opt-in” Users • Everything is more concurrent • How do researchers setting up “slices” know the state of them(and not everything else)? • How do we “shut down” the problem parts (and not everything else)?

  22. Challenge #3: Virtualized Operations • Everything is more temporary • what “slices” are out there (NOW, 3 weeks ago)? • How do we correlate current slices to future slices for repeatability • Everything is more complex • Many different groups to serve: Operators, Researchers, “Opt-in” Users • Everything is more concurrent • How do researchers setting up “slices” know the state of them(and not everything else)? • How do we “shut down” the problem parts (and not everything else)?

  23. Solicitation 2: K-GENI ETRI/KISTI-GENI Collaboration • Scope: • Investigate international operational sharing and federation strategies • Look into interoperability between GMOC and dvNOC • for example: should GMOC conform to dvNOC data formats? vice versa? maybe a international “broker” to translate between them?

  24. Does GENI have any relation to “normal” networks?
