Cold-potato only addresses the long-haul; there's still cost on the receiving network even if its handed off at the closest interconnect to the final destination(s).
And there's still revenue, as the traffic is going to customers (we all filter our prefixes carefully, right?). What's the problem with cold-potato again, or should we all just try to double-dip?

ah yes, double dipping. On-net traffic should be charged a lot less, because after all, it is double dipping.
I can almost smell your sarcasm from here. :) The problem here is that people naively assume all traffic is the same, and costs the same to deliver, which is just not the case. On-net traffic costs significantly more to deliver than outbound traffic, because you are virtually guaranteed that you are going to have to haul it somewhere at your expense. People expect their sub $10/Mbps transit pricing for all services across the board now, without understanding that those rates are ONLY sustainable because of negligible longhaul costs for the outbound traffic. On-net traffic is not "double dipping", it is the ony way that transit can be sold for a particular price. So does that mean that anyone with outbound heavy traffic is automatically taking advantage of a peer? Of course not, because while some types of traffic may indeed cost more to deliver, that traffic is usually *gasp* billed at a higher rate too. Other than spot markets like Cogent trying to prop up its ratios or a small tier 2/3 taking advantage of a 95th percentile billing trick to give away "free" inbound, I would challange folks to find ordinary markets where inbound traffic is not priced substantially higher than outbound, especially in areas outside of the "big tier 1 bandwidth cities". Numbers close to $100/Mbps (or higher) are still perfectly common on OC3's, even on cities which are on major longhaul fiber routes. Remember that content can be moved in order to reduce the cost, eyeballs can not. CDN's deliver bits to the right areas to bypass transport costs, and even ordinary folks choose where to install their servers in order to maximize quality and lower price. Content people who buy transit routinely put their servers at or near major ix facilities in order to get a lower price for the traffic ("hey look my content goes in and out the same pop, or even the same router"). Yes there is an associated cost to deliver access traffic to far-flung regions, but your customers are paying you a higher rate to do it too. So, what is inherently wrong with content customers paying $10/Mbps for a service which is substantially cheaper to provide, and the access customers paying $70/Mbps for the same thing? A lot of people seem to be taking the position of silent resentment towards the folks who are selling content heavy bandwidth at what can only be described as competetive market pricing (meaning, you can buy it at that price from almost anyone). They see such a large volume of traffic and think: a) crap, our network design can't possibly deliver that many bits at those prices in order to compete with them. and b) but man if we were billing all that at $70/Mbps we could, and we would be if not for that damn content-heavy network who is getting "free peering" in to our network in order to sell it for so cheap. We're paying more of the cost for that traffic than they are too, clearly we need to depeer them. Unfortunately they often do so without understanding the symbiotic relationship between the two kinds of traffic, and the two types of networks. If you look at a network like Cogent, it is designed from the ground up to be efficient and cheap at delivering bulk bits from a few customers at a few key points to the rest of the Internet, which is how Cogent is able to erm lose as little money as they do. Their network design looks almost nothing like a network who is optimized to deliver access circuits to a large number of smaller customers across a large number of locations, and it would be far less efficient at it if called upon to do so. In this case, jealousy is blinding a lot of people to the fact that there is room for networks who specialize in content to co-exist with networks who specialize in access, and for them both to add value to each other through interconnection. Specializing in a specific area leads to optimized network designs and reduced costs, and networks who don't may find that they aren't very good (or at least, cost competetive) at either. This naturally leads into two camps: 1) Networks who are more efficient, who end up paying a lot less, and who end up moving a very large amount of bits because of it (but at a much lower price/meg). 2) Networks who are less efficient, who pay a lot more, and who therefore have to charge their customers a lot more in order to survive. These networks face constant attrition from more competetive providers, and quickly realize that access to their single homed customers is one of their only bargining chips left to make people pay a higher price. Yes these are financially trying times for everyone, content and access networks alike. Everyone wants to "take action" to generate additional revenue, or to strike out at networks who are perceived as offering prices which are "too low" based on "dumping" of push heavy traffic and "unfair" cost burdons. Unfortunately in the rush to do that, many networks are actually creating exactly the situation they want to avoid. How much business do you think has been lost to Cogent giving away free or super-low-cost inbound in order to prop up its ratios? How much revenue has been generated by depeering Cogent because of ratio imbalances? The numbers speak for themselves, regardless of who does or doesn't pay a higher amount to deliver the traffic. -- Richard A Steenbergen <ras@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)
