Table III.1 – Alignment analysis with functional requirements in [ITU-T Y.3513]

Functional requirements in [ITU-T Y.3513] Test objects in this Recommendation
17 7.1.6 VM – It is recommended that the IaaS CSP – 7.4 Interoperability testing of VM
clone provides a virtual machine with clone clone between the CSC and CSP
functions. The cloned VM has identical
configuration and CSP/CSC data as the
original one.
18 7.1.7 VM – It is recommended that the IaaS CSP – 7.10 Interoperability testing of VM
backup provides a virtual machine with backup backup between the CSC and CSP
functions. When the VM becomes faulty or
its data is lost, the VM can be restored using
its backup stored according to the CSC
policy.
19 7.1.8 VM time – It is recommended that the IaaS CSP – 7.5 Interoperability testing of VM
synchronizati provides time synchronization functions, time synchronization between the
on which allow the CSC to control the VM time. CSC and CSP
20 7.1.9 VM – It is recommended that the IaaS CSP – 7.6 Interoperability testing of VM
reservation provides processing resources reservation reservation between the CSC and
(such as CPU, memory) functions. Resources CSP
reservation is used to reserve available
resources from IaaS infrastructure before
VM is initiated.
21 7.1.10 VM – It is recommended that the IaaS CSP offers – 7.7 Interoperability testing of VM
image the ability for the CSC to provide and use image between the CSC and CSP
virtual machine images. A VM image consists
of infrastructure configuration and CSP data,
CSC data or both.

22 – It is recommended that the IaaS CSP – 7.7 Interoperability testing of VM
supports a different machine image format. image between the CSC and CSP

23 – It is required that the IaaS CSP provides – 7.7 Interoperability testing of VM
operation handling mechanisms related to image between the CSC and CSP
image，including, but not limited to, add,
import, store, register, deregister, query,
update, delete and export.
24 7.1.11 VM – It is recommended that the IaaS CSP – 7.8 Interoperability testing of VM
template supports the open virtualization format template between the CSC and CSP
(OVF) template, which is a packaging
standard designed to address the portability
and deployment of virtual appliances.

25 – It is recommended that the IaaS CSP – 7.8 Interoperability testing of VM
provides operations handling mechanisms template between the CSC and CSP
related to machine templates, such as
upload, update, disable, enable, query and
delete to the CSC.
