Agree, it is far from obvious what is talked about here, it could be a good idea to borrow terminology from: <draft-ietf-rohc-over-reordering-03.txt>, which is the ROHC document discussing the challenging aspects of reordering. That document is currently in the RFC editor queue. > 2. Then I have a really fundamental question about the > purpose of this draft. It reads like: There is no problem with > reordering in ECRTP, but it might be good to consider these things > Do you intend to change that. I get the same impression, while it is for sure not true that there are no problems. The potential problems that may occur should be carefully described, as well as both decompressor ways to cope with that, along with compressor changes to reduce the risk of failing due to reordering. The big problem is usually not to decompress if one knows which packet it is, but really to not misinterpret the packet due to an unexpected packet sequence. > E2: The draft is lacking page breaks. Yes, please get proper formatting! > E3. The chapters are very funny. All the descriptive text is in the > introduction. Please restructure Would make very much sense! /L-E
