Hi Wei, You raised a comment about CPE identification when a NAT is present on path. I guess you are referring to the general issue discussed in : https://tools.ietf.org/html/rfc7620 In the particular case of call home, we assume that the access provider is the one providing the DOTS service. That is, if there is an address sharing mechanism (not only a basic NAT), that mechanism is also controlled by the same provider providing the DOTS server. The correlation between external and internal reals can be achieved by a variety of means. For example, the use of the NETCONF/YANG (https://tools.ietf.org/html/draft-ietf-opsawg-nat-yang) or the access of the NAT MIB (RFC7659) allow to correlate both the internal and external realms, and therefore identify the appropriate CPE. Please let us know If this clarifies your concern. Thank you. We can update the draft to record this point. Cheers, Med
