Document: draft-ietf-pce-pcep-stateful-pce-gmpls-21 Reviewer: Stewart Bryant Review Date: 2023-06-02 IETF LC End Date: 2023-05-29 IESG Telechat date: 2023-06-08 Summary: I reviewed this from a GenArt perspective (a reader new to the area) and have one request : that early in the document a few sentences be added (copied from another text) clarifying the difference between stateless and stateful PCE. This document is otherwise ready to pass to the RFC Editor team. I note that id-nits picks up a number of errors regarding references (RFC 2119 language and technical references), but the ones I checked seem correct, so I am not sure what is happening. Major issues: None Minor issues: The absence of an early description of stateful PCE as noted above. Nits/editorial comments: Further discussion of concept of a stateful PCE can be found in SB> of the concept For passive stateful PCEs, Path Computation Request (PCReq)/ Path Computation Reply (PCRep) messages are used to request for path computation.
