These are two different subjects. "Difficulty to understand" can be due to insufficient quality of explanations. In this respect, I know what I have written in the past was quite perfectible. I expect the 4rd-addmapping draft to be clearer on several points, but it certainly can be clarified further. Questions raised in the WG are helpful for that. Med: This is IMHO an important aspect for the operational teams who are in charge of dimensioning the A+P space. Easiness of usability is important. "Difficulty to configure" is rather minimal with solutions that are completely stateless. Having "High" complexity for 4rd-addmapping can therefore be misleading. Med: Not all the port indexing schemes on the table have the same complexity level. As I mentioned earlier, we need to depict this somehow. I would really appreciate if you can evaluate other port algorithms and share your evaluation. (The Complexity criterion is also commented in my previous mail.)
