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()

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

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

Provision() Implements an allocation Modifies sliver provisioning
