Med Rev08 #2 how the customer has access to this SDP node information

[lana-wu]

5.2.1. IETF Network Slice Service Demarcation Points

• "node-id": A reference to the node that hosts the SDP, which helps the NSC to identify an SDP.
• "sdp-ip-address": The SDP IP information, which helps the NSC to identify an SDP.
• "tp-ref": A reference to a Termination Point (TP) in the custom topology defined in Section 5.2.5.

Med comment: You may add some information about how the customer has access to this information, especially for PE option described above.

Suggest the following additions:

• SDPs at customer-facing ports on the PEs:As shown in Figure 10 ...

• This document assumes that the NSC can expose abstract topology information, e.g., SAP Network [RFC9408], so that the higher-level system can obtain PE-related node information.

• SDPs within CEs: As shown in Figure 11 ... (This document assumes that the NSC can obtain CE-related information and the implementation details are left to the NSC provider)

@reza-github Could you check SDPs with CE cases how the NSC can access CE SDP information?
