Gigabit not enough?
I am slightly confused. I thought that GPON delivered 2.4 Gbps down and 1.2 Gbps up raw. Subtract 1/5 for overhead leaving 1.92/0.96 actual content throughput. Take half the down for IPTV, 0.96 Gbps, and the customer is left with a 0.96 Gbps symmetrical WWW internet connection. This is not enough?.

Re: Net neutrality
Duh! & Mari,

the point on net neutrality is not relevant. As long as IPTV or VoIP can (and should!) have different QoS parameters than internet data, setting QoS per OTT is not a matter of "neutrality".

The pricing models (including accounting, billing and data caps) are relevant to decide whether the neutrality is challenged or not -- not the QoS or policing settings. Therefore, if OTT data is properly accounted for, and pricing models are not discriminating, no neutrality issues should occur.

In a wider perspective, it all depends how you define a "service" commercially. If your SP sells you a "classical" triple-play data+TV+voice, then OTT is just part of data. But if you pay for data+TV+voice+OTTapp1+OTTapp2+cloud1+cloud2, then each service has its own price and therefore can (and should!) have its individual QoS parameters. With no net-neutrality challenges.

App awareness and per-flow QoS
The article makes some good points in identifying the problem -- but misses on the proposed solution (or Hicks does) completely. It is sad that the article does not mention that the solution is flow classification and policy enforcement per flow, which allow proper policing and QoS per service/app.

App-aware broadband solutions exist in the market since 2010. Readers may have also noted that, nowadays, this is called software-defined access.

Re: Two observations
Good point on the net neutrality issue. When and where broadband is actually competitive, there's arguably not much of an issue with sectioning off some bandwidth for a managed TV service and leaving the rest for broadband. However, where broadband service isn't competitive, there's the possibility that ISPs will limit Internet performance in order to divert enough bandwidth to support a managed IPTV offering.

Two observations
VLANs are integral to the (x)GPON architecture, so by definition (x)PON OLTs are VLAN-capable. I believe that the same is true for (x)EPON. It's a bit more complicated than that, but no technology impediments come to mind for what he suggests.

OTOH, this is exactly the kind of capability that gets Net Neutrality advocates into a lather. The extent to which that will continue to be a problem in the US is not clear, of course.  Might be a show stopper in Canada, Europe and India.
