Re: Packet aggregation vs. point-to-point
I don't really think that's the case.  The only folks who are really deploying that technology are those who need to support legacy TDM with an OTN layer, then it makes some sense to leverage the same platform for both TDM and packet.  Many service providers have converged core networks where the bulk of the traffic is best effort, and that traffic is best carried over large IP pipes, OTN is really just an added unnecessary layer.    It's easy to leverage those same networks for business services.  It's also better to explore network agility at the photonic layer then and not at the OTN layer.

Re: Great story
"There will be plenty of downs as well as ups of course..."

A great vision of a pan-European network -- but a dirty plan to get there: test all the "downs" in less important (?) countries of SE Europe, and shift the implementation of "ups" in Germany to the very end.

Axel used all the possible euphemisms to confirm my statement already: "adolescence", "puberty", "painful first experience"...

Packet aggregation vs. point-to-point

Interesting all IP approach chosen by DTAG. While their all IP network aka TeraStream is extremly router-centric and optical transport plays a rather subordinate role – if at all – other providers go for P-OTN (packet aggregation) with an intelligent and powerful optical layer providing much more simplicity and flexibility like easy integration of Carrier Ethernet.

Anticyclical or decision made too early? Time will show which approach will be more viable in the long run.

Great story
This is a plan that started about 4 years ago and is now happening for real in Europe. DT is truly walking the walk and sharing its experiences.

In 2 years it will be interesting to see what impact it has had in the countries that have switched to all IP in 2015. There will be plenty of downs as well as ups of course...
