Hi Tommy,



_any_ feedback is welcome.



This is a -bis document and it is not intended to change the TCP standards. Within that limit, we should try to come up with the best document we can. The document is owned by the working group. The question what changes will be incorporated is up to the working group as a whole. On that, I have not more to say than any other contributor to TCPM…



Personally, I think that your points are all valid concerns and I can think of ways this can be addressed (at least partially) without disrupting the document. But I’ll leave it to the document editor to comment on the impact.



In a nutshell, I believe your input falls within the very useful categories. Please continue. For instance, if there are other terms that may be outdated, flag them and let us know.



Thanks a lot!



Michael

Betreff: Re: [tcpm] Please review 793bis!



Hi Michael,

Thanks for the note about this (indeed important!) document. I unfortunately had a conflict for tcpm, so missed the recent meeting, but I do have some questions about what the group wants to see in reviews of this document.

As expected, much of the text remains unchanged from RFC793. While I understand and agree that it is a non-goal to change any behavior, reading the document does still feel like it is out of place amongst current RFCs from a terminology and organizational standpoint. If this is going to be published as a full STD document, it would be great to have something that also makes the reading clearer and easier for people new to TCP. Specifically, as some people are now working on implementations of TCP for user space stacks or minimal IoT devices, a clean reference would be a fantastic asset.

Some initial examples of changes that came to mind:

- Structure; there is both a Terminology section (3.2) relatively early on, and a glossary (3.11) near the end. It seems more typical nowadays to have a terminology section up front, and just refer inline to supporting documents (like IP, for example).
- Many of the RFCs referenced are the older or obsoleted versions
- Consistency and freshness; some of the terminology feels dated, such as "the local and remote socket numbers" for referring to what is called "port numbers" elsewhere in the document and in current parlance.

There's a lot of possible work to be done here, so before people embark on such reviews, can you clarify which of these categories of input are useful, and would be incorporated?

Best
Tommy
