Reviewer: Giuseppe Fioccola Review result: Has Issues This document specifies a network YANG data model for attachment circuits and this is a really relevant work. There is a group of related documents (draft-ietf-opsawg-ntw-attachment-circuit, draft-ietf-opsawg-teas-common-ac, draft-ietf-opsawg-teas-attachment-circuit, draft-ietf-opsawg-ac-lxsm-lxnm-glue) and their relation is explained in section 3. While I found the document useful and well-written, it left me with some questions. >From an OPSDIR point of view, I think that some clarification would be helpful. In particular, I would suggest to add more details about the specific-provisioning-profiles specifically in section 5.3. It is mentioned that the exact definition of the specific provisioning profiles is local to each service provider, but I think that a more complete explanation, possibly with examples, may help an implementer to better understand how to use these data nodes. In this regard, it would also be great to describe the usage of the different identifiers (i.e. encryption-profile-identifier, qos-profile-identifier, failure-detection-profile-identifier, forwarding-profile-identifier, routing-profile-identifier) under the valid-provider-identifiers container. I found some considerations about the vulnerability of the specific-provisioning-profiles container in the section on Security Considerations and this is good. -- last-call mailing list -- last-call@xxxxxxxx To unsubscribe send an email to last-call-leave@xxxxxxxx
