Appendix I

Mapping between requirements, activities and functional components
(This appendix does not form an integral part of this Recommendation.)

This appendix (see Table I.1) describes the mapping between BDaaS functional requirements, activities
(described in [ITU-T Y.3600]) and functional components in this Recommendation. The related layers with
[ITU-T Y.3502] are also shown in Table I.1.

It is recommended that the CSP:BDIP supports
collection functional component Service layer
collecting data from different CSN: DPs with (7.1.3.1) (7.1.1)
different modes.
<Clause 8.1 requirement (6)> Perform data Data collection
Data collection can optionally be performed by collection functional component Service layer
the CSP:BDIP in realtime. (7.1.3.1) (7.1.1)

<Clause 8.6 requirement (1)>
Data catalogue Operations
It is required for the CSP:BDIP to manage Publish data functional component support systems
