16:29:24	 From  Lingli-office : No intention for debate. 
16:29:39	 From  Lingli-office : Just trying to understand the requirement for service modeling from 5G applications.
16:29:47	 From  Lingli-office : 5G RAN
16:38:15	 From  Lingli-office : Still confused why we need to depend on network service descriptor as long as we support PNF/VNF, virtual link, and deployment dependency properly in the internal model.
16:39:33	 From  Lingli-office : The diagram we saw several times, the depency from subset slice management towards VNF has two alternative paths: one is via network service, the other is not.
16:40:23	 From  Michela Bevilacqua (Ericsson) : they are not alternative paths 
16:44:05	 From  Thinh Nguyenphu : what is the rational of defining DUaaS, CU-CPAssS?
16:49:50	 From  Lingli-office : @Michela So they are meant for different purposes? which one is for provisioning of VNFs?
