(e.g., are the IEEE documents openly and freely available ?) - should the WG items also include one item about NTPv4 maintenance ? All minor points, so good to go! -éric |

Regarding Éric’s comment about “most widely used”, another option would be to change it to say “it is a widely-used time synchronization protocol”, which I think is indisputable and still gets the job done. 2. I agree with Ben that the references to “quality time” in the first ¶ is a bit jarringly un-idiomatic. The rest of the ¶ implies that what’s meant is that time synchronization must be “reliable” and “accurate”. 3. Is the “shall” in the ¶ about NTPv5 actually intended to be read as an insistent directive to the WG (as one might express it if the writer were unsure if the WG would actually do the work, and therefore wanted to demand that they have to)? Or is it just used as a synonym for the “will” that appears elsewhere? I’d stick with “will” unless the intention really is to communicate insistence. (Compare to the way we use RFC 2119 “SHALL”, for example — would this ¶ scan well if “shall” were replaced with “must”?) 4. s/Finally, the working group, will address/Finally, the working group will address/ (lose the second comma) |

Good quality time is a key component … [Ballot comment] I don't see milestones (either existing or proposed) for interleaved mode or alternative selection algorithms. Good quality time is a key component of all modern systems, devices, and applications. This quality time requires reliable and accurate network time synchronization over modern IP-based networks. "[Good] quality time" is probably a term of art for the WG members, but is also used in informal English to mean something completely different. I don't know if it's worth the effort of rephrasing to be able to specify which of accurate/precise/reliable/regular/stable/synchronized are the specific relevant attributes. The working group will continue to to address the maintenance of NTPv4 including extensions and corrections. This includes the introduction of a interleave mode in order to enhance the accuracy of the network time synchronization and the introduction of alternative selection algorithms in order to enhance robustness against delay attacks. Are "selection algorithms" just "clock selection algorithms" or something else? It might be worth clarifying. Despite its increasing importance, NTP remains vulnerable to many types of attacks. [...] (nit) This seems like a strained connection; a protocol's (in)vulnerability is a function of the specification work it receives, not its importance. The latter might drive some of the former, but it's not guaranteed. The working group will work on extending NTS to cover the remaining modes of service for NTP not covered by the initial version. It looks like we would still be using the existing NTPv4 codepoint for this NTS application, so maybe s/initial version/initial specification/ is better. * NTPv5 specificaition(s) Hmm, looks like https://www.rfc-editor.org/errata/eid6588 is catching. |
