For a minute there, I thought you might be right since I'm browsing for clue factor and may have missed something, but, it appears you are inaccurate in this as the poster did say: --QUOTE "If a single-homed network moves from L3 to Cogent, how would they benefit? Would they not still be cut off from a significant percentage of the Internet? Is it reasonable to think that numerous /24's from L3's IP space could be reassigned elsewhere without causing significant trouble for L3 and others? Even if it could work, what would be the justification for taking L3's property?" --END QUOTE That quote is asking if someone can take Level(3)'s PA space assigned with them to another providers network. The answer is yes, it's possible. IANAL

Thank you, Paul. I'd be interested in your feedback on these thoughts of mine below. I do believe it is typical, perhaps with some variance but usually amounting to the same thing, that end-users are billed for the "highest of in vs. out" traffic, roughly the capacity they are provisioned. Thus if I may, I'll build on this to make a more concrete statement: each party in a peering relationship receives equal value for traffic exchanged. (traffic volume at the SFI translates into revenue from end-users) Things aren't so simple in reality, though: you have to look at the element left out of my statement above, the "cost" of traffic exchanged. If one peer terminates more traffic than it originates, and the originating peer is performing "hot-potato" routing, then the terminating peer typically has a higher cost burden as it has to transport the traffic the greater distance. However the opposite holds true if the originating peer is performing "cold-potato" routing. Thus, such things exist as traffic in/out ratios between peers. But this is a blunt tool which seems to help enforce the exclusivity of the Tier-1 club, and actually acts as a barrier to competition. That is, anybody with a different traffic pattern (i.e., because of a different business model) will be excluded from the club despite the fact that they bring equal value in the form of traffic volume to the relationship. And club-outsiders are subject to increased relative operating costs (cost of revenue) compared to club-insiders. So what is the solution? "Warm-potato" routing seems possible technically, providing an approximation of cost-burden fairness. Is the benefit worth the complexity to manage in practice? And clearly, I'm not advocating endless open peering--the revenue element of the equation (customers) must exist. So what is the best way to determine the criteria by which a network is determined to be a "peer"? Cheers, -Benson --- Benson Schliesser (email) mailto:bensons@savvis.net I barely understand my own thoughts, much worse those of my betters. Thus, the opinions expressed herein are not necessarily those of my employer. Ponder them at your own risk.

Problem is, everyone's right of expression is distorted to everyone elses to some degree. Your opinion is your opinion no matter how right or wrong. You'll always have agreements and disagreements. This has always followed suit throughout ages whether it is/was a religious view, political view, personal view, etc. That's just life.

Disagree. Some corporations should have checks and balances just like individuals do. You say you disagree now but what happens if say Google become the only ISP in town, the only search engine in town the only whatever in town, then down the line they decided to create an inflated (non regulated) price on their services. You surely would be crying foul. Anyone would. Sort of like companies bound to Microsoft because of the costs associated with revamping infrastructures. Now you have tons of DDoS zombies, warez warehouses, trojan factories, worm heavens thanks to MS' lackadaisical attitude toward security. Funny thing happened on the phone with an MS salesgoon... me: "I'd like to know about MS Exchange since my boss wants it. I have X_amount of employees." him: "Well you would pay X_amount of money but you could only use X_amount of space on your exchange server" Me thinking to myself... "I'm paying X_amount of money for X_amount of people and MS is telling me how much space I could use on my own hard drives... No matter how many "seats" I buy..." Screw MS... And yes I had a hardy laugh as did the salesgoon who was trying to extort (yes extort) me on what I can use on my systems. Anyhow I thought it was funny and laughed at him on speakerphone...

It > should be clear that the nature and extent of this network depends > very much on the perspective of the connected device from which is it > measured. At last, a definition we can all agree on! ;) Honestly this might be closest to the truth, but it's not quite the perception that the marauding forces of marketing have encouraged over the previous 10 years. Rather, the market which exists to support ISPs tends not to include people who understand the nature of the network, and its instability. Sadly, for many of the market constituents the "Internet" equates to the "Web"; for some of them it equates to a platform to support their applications; for very few of them does it equate to a unique perspective into a subset of possible IP relationships. As I said, this definition is closest to the reality today, but not even everybody on this knowledgeable mailing list feels happy with buying such a service, no less so the end-users at large. > Do people in Spain complain that they can't call numbers starting > with +350, and insist on getting money back from their monthly bill? > Or do they accept that their government has an ongoing dispute with > the UK over whether Gibraltar is in fact part of Spain? Good counter-example. Instead of trying to compare how this example of political dispute and the resulting customer satisfaction or frustration is similar to the Cogent-Level(3) situation, I'll simply acknowledge that my analogy, like most, is imperfect. I still hold to my fundamental point, however. The market has evolved to expect more than "Internet as an research experiment/hobbyist toy", and now expects the "Internet" to be a component of their critical infrastructure. Service providers that don't understand this, in addition to having unsatisfied customers, may perhaps incur outside intervention. Would that ultimately be so bad for end-users?

Fw: Nuclear survivability (was: Cogent/Level 3 depeering)

It's not a myth. If the Internet were running RIP instead of BGP that is likely what would happen. Of course, there are a few downsides to running RIP on the open Internet as well... Today's Internet is a few generations beyond what Paul Baran originally conceived and the policy and politics of business does tend to gum up the works a bit now that there is no serious threat of global nuclear war. --Michael Dillon
