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.
