Hi I hope that I am not too late with the review.
Perhaps this has been brought up earlier, and it that is the case then sorry for kicking in open doors. I have read but to not seen any mention of the initial congestion window size. Today the initial window in most TCP stacks is set to 10*MSS and this may well be used by Nb-IoT implementers that are unaware of default settings. While this is likely not an issue if he applications transmit small objects that fit in a few segments, it can become an issue with larger object transfers and if a burst of 14600 bytes overflows a tiny network buffer. Should this be addressed, possibly with a recommendation to adjust the initial window based on network constraints ? /Ingemar ================================== Ingemar Johansson M.Sc.
