Last Call Review of draft-ietf-v6ops-rfc6555bis-05
Reviewer: Zitao WANG
Review result: Ready
I have reviewed draft-ietf-v6ops-rfc6555bis-05 as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written with the intent of improving the operational aspects of the IETF drafts. Comments that are not addressed in last call may be included in AD reviews during the IESG review.
Document editors and WG chairs should treat these comments just like any other last call comments.
"This document specifies requirements for algorithms that reduce this user-visible delay and provides an example algorithm, and expands on "Happy Eyeballs" [RFC6555], a technique of reducing user-visible delays on dual-stack hosts. Now that this approach has been deployed at scale and measured for several years, the algorithm specification can be refined to improve its reliability and generalization. This document recommends an algorithm of racing resolved addresses that has several stages of ordering and racing to avoid delays to the user whenever possible, while preferring the use of IPv6. Specifically, it discusses how to handle DNS queries when starting a connection on a dual-stack client, how to create an ordered list of destination addresses to which to attempt connections, and how to race the connection attempts.”
My overall view of the document is 'Ready' for publication.
One small comment is that there are some id-nits, please fix it in next version:
(See RFCs 3967 and 4897 for information about using normative references
to lower-maturity documents in RFCs)
