| This is Telco's equivalent to Cable node overload The %'s are significant, because they are congestion on ATM ports. ATM doesn't mean money; it is a telco protocol similar to IP that does not deal well with congestion. A 1500-byte TCP/IP packet might be split into 32 53-byte(48-byte payload) ATM cells.. Losing one cell means the other 31 cells are toast, even if they are delivered.
What this effort by Bell Canada shows is that the changing utilization rates of DSL customers vs. the backhaul bandwidth to DSLAMS is putting the squeeze on Bell and they want to curtail it, rather than try to keep up with it. Keeping up with it means higher wholesale DSL line charges, or higher costs for ISPs backhaul circuits to connect to the DSLAMs.
As you might recall, British Telecom has been screeching about the same thing because of BBC iPlayer.

I haven't seen BT complain about iPlayer (indeed, their own IPTV service now includes iPlayer content, but at a price). If they did, it would be in the context of their own retail network, not the wholesale ADSL network that other ISPs also use (and that'll change when they get their IP network up and running).
Nor have they floated the idea of traffic shaping on the wholesale level.
The only ISPs I have seen complaining are the likes of Tiscali which cut costs everywhere and their customers wonder why dialup is faster. | |
