Hi Gunnar, On Tue, May 25, 2021 at 12:29:51PM +0200, Gunnar Hellström wrote: > Benjamin, > > Continuing the answers with the last part., Thank you for going through them all. To be clear, I was not waiting for you to finish before I started replying -- I just had a deadline earlier today and did not have a chance to do much with my email sooner. Having the content chunked up into multiple pieces can make it easier to manage. This is the only message I'm going to respond to, though, since I basically have nothing further to say. (I've already updated my ballot position to remove the Discuss.) I'm really impressed with how you took my comments and turned them into improved text in the document, especially in the places where I did not have a clear proposal. I also appreciate your explanations in the places where my questions did not make sense or are already covered by some of the fundamental documents in this space; the gaps in my knowledge are slowly getting filled in. > Den 2021-05-19 kl. 04:53, skrev Benjamin Kaduk via Datatracker: [...] > [GH]Again, thanks for a thorough review and many good proposals for changes. I must thank you again for your thorough responses; I feel like I am not doing them justice by only sending this one short note, but do not want to make you read through a repetitive set of "yes", "this sounds good", "thank you", etc. I read through the changes in the already-uploaded -19 (thank you again!), and there were only two items that might be worth following up on (both in section 3.16.3 of the -19): You had proposed: [GH] Would it be sufficient to insert the words "and reordering" in the first two sentences in the paragraph to read: "The receiver SHALL monitor the RTP sequence numbers of the received packets for gaps and packets out of order. If a sequence number gap appears and still exists after some defined short time for jitter and reordering resolution, the packets in the gap SHALL be regarded as lost." I don't think this made it into the -19; my preference is to use your proposed text that includes mention of reordering, but I do not insist on it. There was also a mention about the procedures for extracing T140blocks with the redundancy procedure, where we currently say "T140blocks SHALL be extracted in the following way. The description is adapted to the default redundancy case using the original and two redundant generations." While I am inclined to agree that the extension to the generic case with other levels of redundancy is something that the reader can be expected to perform, it feels a little incomplete to say that something "SHALL be [done] in the following way" but give a not-complete/not-generic procedure. Only for that reason do I prefer to have an explicit indication that the procedure might need to be adjusted for a different level of redundancy; as for the previous point, I do not insist on any change, though. Thanks again, Ben
