Right. That's why I prefer the solution space provided by Med before, which will be much clearer and easy to understand: * Full stateful approach * Binding approach * Full stateless approach Best wishes Qiong On Fri, Nov 30, 2012 at 12:13 PM, Leaf yeh leaf.y@huawei.com wrote: Mark - I

Hi, While thanking the authors for their attempt, I need to provide some high level feedback first on key issues: The rationale section 1.1 states co-existance as the goal - this appears to imply some entirely different solutions for which co-existance is needed, and here are two points: A) I can

And much as was also said before, this categorization is bogus as all solutions need configuration state, ie categorizing solutions based on amount of configuration or some fluffy term like binding approach is equivalent to categorizing them based on how long is a piece of string and ultimately

This solution space is the outcome of Vancouver meeting. And IMO, the word 'binding' not only means there are state to maintain, but also indicates that IPv4 and IPv6 addresses are just bound together, with no algorithmic relationship. Thanks, Qi Sun On 2012-11-30, at 下午6:51, Wojciech Dec
