9.3.2 User account and profile management

The UAPM-F creates CSU's account with CSU's access information through I_UAM_UAPM. The UAPM-F has
two more reference points I_CCM_UAPM and I_PA_UAPM for authentication with CSU's account information
and for the pre-configured environments and profiles, respectively. When RAD-F allocates and distributes
resources, the UAPM-F provides CSU's account information on I_UAPM_RAD or I_UAPM_OPM. Detailed
functional description for the UAPM-F is specified in clause 7.3.2.

9.3.3 Virtual desktop resource allocation and distribution

The RAD-F has a reference point of MC-F through I_RAD_MC with monitoring information to analyse resource
usage. I_IAM_RAD enables the RAD_F to approach IAM-F and resource assignment function (RA-F) for
resource assignment. A detailed functional description for the RAD-F is specified in clause 7.3.3.

9.3.4 Operational policy management for DaaS
The OPM-F has two reference points I_OPM_PM and I_OPM_MC to receive the performance or resource
usage which is used to establish the policies. These policies are applied to PA-F with I_PA_OPM. A detailed
functional description for the OPM-F is specified in clause 7.3.4.

9.3.5 High availability for DaaS
The HA-F has only the reference point with the MC-F through I_MC_HA in order to monitor the resource
state for establishing the related policies. A detailed functional description for the HA-F is specified in
clause 7.3.5.

9.3.6 Power management of virtual desktop resource
The PM-F collects performance information from the MC-F through I_MC_PM and transfers the power
related information to the PA-F through I_PA_PM for efficient provisioning. A detailed functional description
for the PM-F is specified in clause 7.3.6.

9.4 Virtualization infrastructure functions
The VI-FS has four functions including performance enhancement for virtualization platform function (PE-F),
IAM-F, RA-F, and platform virtualization function (PV-F) as shown in Figure 9-4. The VI-FS provide the
interfaces with the other two function groups, VDCD-FS and VDRM-FS.
