Reviewer: Rifaat Shekh-Yusef Review result: Ready I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. RFC8453 is an informational document that defines a Framework for Abstraction and Control of TE Networks (ACTN), with a well defined security considerations section. This is an informational document that examines the applicability of Path Computation Element (PCE) to the ACTN, by adding PCE to the PNC and MDSC controllers. The security considerations section seems to be aligned with the security of the ACTN framework, and the addition of PCE to the existing controllers does not introduce new security concerns beyond what is already covered by the framework.
