  1. Update() Proposal Jonathon Duerig, Robert Ricci

  2. Goal • Allow Experimenters to Modify Existing Slivers

  3. Overview • New API Methods • Update() • Cancel() • New Allocation State • geni_allocating

  4. Current State Machine Allocate() Provision() geni_ unallocated geni_ allocated geni_ provisioned Delete() Renew() Renew()

  5. Update() • Parameters • Urns -- List of slivers to modify • Rspec -- Complete request specification for all slivers included in the urnslist • Changes user allocation, not provisioning • Existing sliver provisioning is unchanged

  6. State Machine Allocate() Provision() Update() geni_ unallocated geni_ allocated geni_ provisioned geni_ updating Renew() Renew() Renew() Delete()

  7. State Machine Allocate() Provision() Update() geni_ unallocated geni_ allocated geni_ provisioned geni_ updating

  8. Cancel() • Cancel an allocation • Returns sliver to previous state • Provisioned slivers not perturbed

  9. State Machine Allocate() Provision() Update() geni_ unallocated Cancel() geni_ allocated geni_ provisioned Cancel() geni_ updating

  10. Provision() • Implements an allocation • Modifies sliver provisioning

  11. State Machine Allocate() Provision() Update() geni_ unallocated Cancel() geni_ allocated geni_ provisioned Cancel() geni_ updating Provision()

  12. Update() Rspecs

  13. Update() for modify • Urns: sliver+35, sliver+36 <rspec> <node sliver_id=“sliver+35” …>…</node> <node …>…</node> </rspec>

  14. State Machine Allocate() Provision() Update() geni_ unallocated Cancel() geni_ allocated geni_ provisioned Cancel() geni_ updating Provision()

  15. Update() for create • Urns: sliver+35, sliver+36 <rspec> <node sliver_id=“sliver+35” …>…</node> <node …>…</node> </rspec>

  16. State Machine Update() Allocate() Provision() Update() geni_ unallocated Cancel() geni_ allocated geni_ provisioned Cancel() geni_ updating Provision() Delete()

  17. Update() for delete • Urns: sliver+35, sliver+36 <rspec> <node sliver_id=“sliver+35” …>…</node> <node …>…</node> </rspec>

  18. State Machine Update() Allocate() Provision() Update() geni_ unallocated Cancel() geni_ allocated geni_ provisioned Cancel() geni_ updating Provision() Provision()

  19. Update() Allocations • Modifies allocations • geni_allocated • geni_updating • Slivers remain in same state • Attached to modified allocation

  20. State Machine Update() Allocate() Provision() Update() geni_ unallocated Cancel() geni_ allocated geni_ provisioned Cancel() geni_ updating Provision() Update() Update() Provision()

  21. State Machine Update() Allocate() Provision() Update() geni_ unallocated Cancel() geni_ allocated geni_ provisioned Cancel() geni_ updating Provision() Update() Update() Provision()

  22. State Machine Update() Allocate() Provision() Update() geni_ unallocated Cancel() geni_ allocated geni_ provisioned Cancel() geni_ updating Provision() Renew() Update() Renew() Renew() Update() Delete() Provision()
