Re: [CCAMP] Question on draft-zheng-ccamp-yang-otn-slicing-03

Hi Reza,

Thank you for the comments. I agree with you that from the IETF NSC
perspective, OTN-SC can be seen as just an NS realizer for underlying OTN
technology. Additionally, OTN-SC could use the same interface to support
technology-specific slicing for OTN-aware customers. These points can be
captured in the next revision of the draft.

Thanks,
Aihua
