Re: demand for DMM traffic steering

Intense reading… :-) Lot of abstractions, which I can only follow by relating to specific solutions.

In my understanding, what Sri is describing is about "how to apply UP/CP separation to various DMM solutions".
In the examples I see a number of DMM solutions defined with UP/CP separation using Sri's terminology (e.g., per-flow mobility, access network anchoring, host-specific route based solutions, etc).

So, it's not a solution by itself, but it's an approach that can be applied to various solution techniques to SDNize them. 
And that indeed has value.
