Hi Tom, I think this document would be helpful for operators to understand different solutions. Just two quick questions: 1) As now the outline is a little similar to the deployment drafts of different solutions, are you going to give step-by-step guidance for readers about how to deploy these solutions, or just the comparison among them ? For me, I think this draft should focus on the differences and readers can refer to each deployment draft for further reading. 2) Does this draft only cover softwire solutions ? As far as I know, T-mobile has deployed XLAT in their LTE network. So should XLAT be included in this draft?
I may come back with further comments. Thanks! Best wishes Qiong On Fri, Mar 7, 2014 at 4:36 AM, Tom Taylor <[email protected]>wrote: > Comments and additions are invited.
