Being a relatively younger network, we have the benefit of not having too much legacy kit running around. It also means we're building at a time when vendors are reasonably putting out dense, modern kit. Right place, right time. I'll admit that this is a harder problem to solve unless you're looking at current generation Ethernet edge boxes. But then again, if you aren't looking at these, chances are you don't have this problem anyway. > It is certainly not ideal to place them on an edge device > then buy another pair or two to just uplink/passthrough > to the core to passthrough to a peering edge. The core will have been there long before you customers start ordering 10Gbps circuits. Provided you have the right platform in the core, scaling up will neither be an issue nor a problem when you have downstreams buying dozens of 10Gbps circuits from you. For folks whose core is aggregating non-Ethernet circuits too, it's not trivial to throw such links into a P/PE device optimized for Ethernet. This may not necessarily justify having an independent core layer, but if you're big enough, maybe it is, among other reasons. There is a reason Cisco and Juniper built multi-chassis systems, even if I don't necessarily subscribe to the idea even today :-). > We may be networking but just on different scales.

Agree, and working out the cost is not just a function of whether you can do more with less. There's also avenues such as special discount levels or relationships with vendors to exploit. These are the bits, unfortunately, that won't make it into the monthly industry journal :-). > It may also be the market in your part of the world can > bear these higher costs. Like I said, cost isn't necessarily the only hand you have to play. At these networking levels, it's more than a "Hi, bye" between you and the vendors. Every ISP networking at these kinds of bandwidth levels knows that. > I've been hearing of sub-$1/meg > contracts. Me too. > Not sure what your price per meg is with all > those layers. It's competitive - we don't rely only on the kit to pay for itself :-). But I digress... > I'm seeing one player come back at nearly > $100/meg in the us.
