Update() Proposal

Jonathon Duerig, Robert Ricci

Goal

• Allow Experimenters to Modify Existing Slivers

Overview

• New API Methods– Update()– Cancel()

• New Allocation State– geni_allocating

Current State Machine

geni_unallocated

geni_allocated

geni_provisioned

Allocate() Provision()

Delete()

Renew() Renew()

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

• Modifies allocations– geni_allocated– geni_updating

• Slivers remain in same state• Attached to modified allocation
