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 geni_ unallocated geni_ allocated geni_ provisioned Allocate()Provision() Delete() Renew()

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

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

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

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

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

10. Provision() Implements an allocation Modifies sliver provisioning

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

12. UPDATE() RSPECS

13. Update() for modify Urns: sliver+35, sliver+36 …

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

15. Update() for create Urns: sliver+35, sliver+36 …

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

17. Update() for delete Urns: sliver+35, sliver+36 …

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

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

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

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

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