I think the NSC is going to be aware of the customer ID/name, so that in the provider's context the NSE is identified by {customer, NSE ID}. I'm pretty sure the point here is that the NSE identifiers form a set across all of the slices that a single customer has and the NSE IDs are, therefore, unique within the customer scope not within the scope of a slice. I don't see a typo to change here. > 4. Page 20, 'IEFT' typo Yes > 5. Page 20, 'are mapped to the underlay IETF Network Slice Endpoints > (NEPs)'. The abbreviation could be NSEs while not NEPs. Oops 😊 Actually, this should be "EP" as in the diagram. A little additional tidying of the text is needed. > 6. Page 24, security consideration, 'as some aspects of security may be expressed > in SLOs.' > According to 4.1.2.1, security is expressed in SLE, and here, the SLOs could be SLEs. Oh, well found! Best, Adrian
