Hello Marcel
Well ... knowing you have 27mbps downstream on Docsis (34 using EuroDocsis), and I am sure you have more that 3 people per headend ... I suppose that "best effort" is the right word ...
I am not sure since I am little bit away from this technology at the moment but maybe DOCSIS 3.0 (a.k.a. "Wideband DOCSIS") is already out in the field...
--snip from http://www.cablemodem.com/primer/ DOCSIS 3.0 will increase the capacity to a minimum of 160 Mbps downstream to customers and by a minimum of 120 Mbps upstream. --snap
