Hello I have been selected to do a routing directorate “early” review of this draft. https://datatracker.ietf.org/doc/draft-ietf-tcpinc-tcpeno/ As this document is in working group last call, my focus for the review was to determine whether the document has any potential impact on routing applications (BGP, LDP, etc.). Document: draft-ietf-tcpinc-tcpeno-12 Reviewer: D.Papadimitriou Review Date: 28-10-2019 Intended Status: Experimental Summary: I have some minor concerns about this document that I think should be resolved before it is submitted to the IESG. Comments: - May be the document can document if there is any modification for what concerns closing of connections (in its current version the document provides a requirement in Section 5 but no actual procedure) Nits: - Include ref. for Section 3 on Terminology (SYN, ACK, etc.) - Section 4 states " It uses a new TCP option kind " may be worth explaining which *new* kind ? - s/ 4.5. The Negotiated Tep/ 4.5. The Negotiated TEP Thanks, -dimitri.
