musings ....

on peering, transit, and why Vadim should be flogged... :) Vadim (i think) frist coined the term Tier-N for classifying ISPs. Nice marketing term. wrt peering, tranist, and the relative importance of communications channels... ) the PSTN is not ubiquitious ... it is NOT possible to dial and be connected to every known telephone number from every/any possible number. Goverments do block access to some other places they find objectionable. ) "the Internet" is and (nearly) always has been a collection of networks, the interconnection of which is bound by policies. those policies are there to restrict/interdict/block traffic of one form or another. (how many of you -want- BGP w/o the policy knobs?) ) if communications w/ someone or some entity is critical, it behoves me to ensure that such channels are available. that may entail me owning the ROW, the transmission media, and the CPE at each end. Or, for less critical channels, I might be able to aquire such services from suppliers. For even less critical communications, I might even presume that my suppliers and their various associates and fellow travelers in the IP pipe business will get my various bits to the random places that I try to send them to on a whim. And... that the other bits will get back to me. :) don't want to talk about content. :( --bill (who has enable, has negotiated peering and transit, and is dumbfounded at the length of this thread)

If both the sender and receiver are being billed for the traffic by their respective (different) service providers (all other issues being equal) is one provider in a better position than the other?

Public Works Peering

Of course those making financial decisions would likely hate this idea since it would somehow manage to "hurt" their business in their eyes... States (or countries) would create a massive public NAP which would be peered in each state. Guaranteed not to go down. Well 99.99999% (snicker) guaranteed not to falter. This network would be funded by taxpayer dollars and anyone wanting to peer would pay solely enough to maintain this NAP. A consortium of companies using this NAP would engineer the network since most times government officials have little clue on the engineering side of things, nor would they understand it more than those already in the industry. This NAP would be unbiased as to "my bgp tables are bigger than yours" arguments, and would pass traffic unbiased to most destinations without flaw. I'm not one for any type of government intervention but at current pace, how long would it be before the lawsuits start coming out of de-peering (is that actually a term). In the long run it is not beneficial in my eyes for companies to start shafting each other via capitalistic methods of who will pass traffic to whomever else. I know for one as the end user, I would be highly upset if two separate companies depeered and affected my company's workflow. I would also be even more upset if somehow de-peering affected my life/lifestyle or that of my family in some capacity. Think of something along the lines of dare I say "national security" for INSERT_YOUR_COUNTRY_HERE. What if two main infrastructures were broken because someone de-peered from another provider. Far Fetched Scenario: Lt. Jones "Sir we've lost all connections with $FOOBAR_DEPARTMENT... People can die if we don't get the proper information..." Senior Lt. Doe "How did this happen! We have a delivery of medical supplies... Track them down." Lt. Jones "We can't sir. We have no connectivity" Senior Lt. Doe "What do you mean" Lt. Jones "Well a provider de-peered..." Sure it's far fetched to a degree, but there are industries outside of government that could seriously be affected by de-peering actions. Health industries, say the insurance companies right now helping out natural disaster victims... I could think of an insane amount of scenarios that could happen because of actions such as those taken by L3 and Cogent. Somewhere along this thread is a VOIP thread spinoff... So what about people who can't dial (e-)911 right now. People can die if you think about the worst case scenario because of nothing more than greed. So for those who reply back with some "go to hell" like message I suggest you go back to your core and read up on ethics and morals before putting a dollar sign on a life. /* EOF MORAL RAMBLINGS */ Anyhow, I could see a benefit to having say a public works NAP. Outside of monopolistic reach working rather well. =+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ J.

Fw: Peering vs SFI (was Re: Cogent/Level 3 depeering)

> Time to quote Geoff Huston one more time. > > "A true peer relationship is based on the supposition that either party > can terminate the interconnection relationship and that the other party > does not consider such an action a competitively hostile act. If one > party has a high reliance on the interconnection arrangement and the > other does not, then the most stable business outcome is that this > reliance is expressed in terms of a service contract with the other > party, and a provider/client relationship is established" Those people less versed in the art of peering may not understand why the peer who has been disconnected does not consider the action to be competitively hostile. Simply put, in a true peer relationship, the party who terminates the interconnection is shooting themselves in the foot and inflicting as much commercial pain on themselves as they are inflicting on their peer. The reason that it is not "competitively" hostile is because it does not increase the ability of either peer to compete. Rather, it damages both of them equally because true peers are equals to begin with. As vijay points out, this whole issue is not really about true peering because such equality between peering partners is rare. It's really about the business case for settlement free interconnect and that is rather more complex than merely the choice between "free" traffic exchange and paid transit. --Michael Dillon P.S. would the Internet be worse off if all traffic exchange was paid for and there was no settlement free interconnect at all? I.e. paid peering, paid full transit and paid partial transit on the menu?

depeering season?
by Jon Lewis 06 Oct '05

06 Oct '05

I've been told verbally (still waiting for it in writing) that UUNet and TWTC (4323) are about to depeer (today?). I wouldn't have guessed TWTC had SFI with UUNet...so maybe they're just falling back from paid peering to cheaper transit. ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
