Reference points of inter-cloud computing
(This appendix does not form an integral part of this Recommendation.)

As described in this Recommendation, inter-cloud functional architecture reuse the functional components
of [ITU-T Y.3502] and extends BSS, OSS, integration and security system functional components with inter-
cloud functions. Given no detailed interactions and reference points have been defined in [ITU-T Y.3502]
between functional components, this appendix provides examples of inter-cloud related reference points for
informative purposes.

The reference points of inter-cloud computing architecture are shown in Figure II.1.

Figure II.1 – Reference points of inter-cloud computing architecture

II.1 Reference point: I-SSM-Blg
The subscription management functional component interacts with billing functional component through
I-SSM-Blg to provide inter-cloud service subscription information for billing.

II.2 Reference point: I-SSM-IPM

The subscription management functional component interacts with incident and problem management
functional component through I-SSM-IPM to synchronize inter-cloud incident- and problem-detecting and
reporting information.

II.3 Reference point: I-SSM-MR

The subscription management functional component interacts with monitoring and reporting functional
component through I-SSM-MR to get the monitoring information of inter-cloud services of different inter-
cloud service subscriptions.

II.4 Reference point: I-SSM-SC
The subscription management functional component interacts with service catalogue functional component
through I-SSM-SC to synchronize inter-cloud service catalogue information.
