Hi Tom, I would like to assist on that. I'm finishing writing my Master Degree Thesis comparing DS-Lite, 464XLAT, MAP-E and MAP-T performance. I got of one CGN + encapsulation (DS-Lite), one CGN + dual translation (464XLAT), one A+P + encapsulation (MAP-E) and one A+P + dual translation (MAP-T).
At the moment I have collected performance (throughput, jitter, latency, packet loss and overhead) and user experience (Internet access, Torrent, Skype etc). I used a small scale network with ISC's DS-Lite implementation and CERNET's MAP-E and MAP-T implementation. For the 464XLAT I had to use Tayga, as the current solution being used at T-Mobile is Android only and Tayga was the only way I found to implement 464XLAT without using Android and allowing me to have the same network for all the tests. I was already planning to write a summary of my results as a draft when I had finished everything. Your proposed scope is larger than mine as you are proposing to analyze more techniques and do planning / management considerations, but I believe I can assist you.
