"8Mbit/s with ADSL, 25Mbits/s with ADSL2+ and 28Mbits/s with VDSL"

Well, it is harder to comment on VDSL (by which I actually think they mean VDSL2) because there are multiple profiles with different capabilities.  But other than that, the speeds stated here are the baseline specification speeds and anybody that wanted to pass the UNH test suite had to hit those anyway.  And that is without DSM or G.Vector or anything else.

We were deploying 10Mb/s over .bis way back in 02/03 with the IOCs to deliver video (2 streams of SD).

re: Telco CDNs Make OTT Tolerable

Along with CDN standards, the industry needs better understanding around what CDNs are and are not.

CDNs are more than caching systems.  And if CDNs are intended to make OTT tolerable, then CDNs for brining VoD closer to consumers won't alleviate that problem.

While CDNs offer real benefits to operators, realizing them will be a challenge without clearer definitions.

I agree there is more to CDNs than caching. I would also agree that CDN functionatlity probably needs to be defined.

ATIS is already jumping into this process and produced its first results in record time: http://www.lightreading.com/document.asp?doc_id=209394

Telco CDNs have the potential to make OTT more than just tolerable.  If they do it right, telcos can profit handsomely from OTT traffic.  

Here's how they can do it:  How Telcos & ISPs can learn to love OTT
