I think (1) is fine. I don't really think this document is needed, but I also don't think it hurts anything as a clarification. It could also be a bit more clear and succinct. A few comments below, but in general "eh, whatever". allman Section 1: - I find this ... It is important to remember that ACK (acknowledgement) segments that contain no data are not reliably transmitted by TCP. Therefore zero window probing SHOULD be supported to prevent a connection from hanging forever if ACK segments that re-opens the window is lost. confusing. I understand the first sentence, but I cannot parse the second. I can guess what it is trying to say, but it needs fixed. Section 3: - The sender does not necessarily dump "all" data into the send queue. It depends on how big the send buffer is and how much data needs to be sent. Section 5: - This: It also suggests that TCP MUST not abort any connection until either explicitly requested by the application to do so. makes no sense. Is that "MUST not" or "MUST NOT". Usually there are two options after an "either", but I see only one. I would normally think this is a spurious "either", but here am somehow thinking there is an option that was forgotten. Meta: - Isn't the overall point of this document to clarify things to say that (1) a TCP cannot tear down a connection itself, (2) the application can abort a connection and (3) the OS can abort a connection? If I am remembering this right then this could and should be called out **much** better in the document.
