We're hoping we don't have to do any QoS or shaping, as we don't want any links to be saturated. From the data i've gotten it seems that is possible with many hundreds of 100Mbit customers on a 1000Mbit backhaul.----- Original Message -----From: "Adam Armstrong"<lists () memetic org>Residence customers will tolerate a lot more oversubscription than business, enterprise, and server going on down the list of oversubscription, but happily *up* the list of "how much can I charge". Remember that QoS and load shaping don't work all that will across the internet at large, but they work pretty decently inside a single switch; you can prioritize customers who are willing to pay extra for it. The problem is similar to airline bookings; it is possible, in the immortal words of Dave Barry, to envision a situation -- this will happen in your lifetime -- where no two customers pay exactly the same price. :-)
The 1G product is the exception to that, and it's a little unclear where that sits, probably in a box labelled "here be failure".
