FWIW, this study claims backbone traffic in the US is doubling every six months. http://www.caspiannetworks.com/pressroom/press/08.15.01.shtml http://www.caspiannetworks.com/library/presentations/traffic/Internet_Traffi... (We've reached the day when PowerPoint and press release constitute a scientific study.) i saw this one yesterday and was ... uh ... intrigued does anyone have any idea what data they used? ('top 19 carrier...') i almost posted it to nanog but questioned the operational relevance of numbers that are not differentiated methodologically from those generated by rand(); [and as such i probably shouldn't responding to this post...] actually i saw the story here: http://siliconvalley.internet.com/news/article/0,2198,3531_866741,00.html quotes: "We are also seeing that 50 percent of the traffic is being carried by four of the major ISPs," says Roberts. Those being AOL (NASDAQ:AOL), MSN, Earthlink, and SBC. i guess "19 NDA's, sorry, can't say more" comprises a methodology? that's a nice deal he's got; most of us can't get away w that... Roberts' work represents the first hard data collected on Internet traffic since the U.S. National Science Foundation discontinued monitoring network statistics in 1996. hrrrm.... not sure i'm okay with that sentence... "But, based on what I've seen, the traffic should increase every six months." whoa that's really going out on a limb... yeesh k

Serious question: What about EarthLink's non-EarthLink-owned modems? (They do lease some modems, I have dialed into one before. :) And what about NetZero-type companies that outsource all of their modems? If he is measuring traffic off routers, I do not see how he could differentiate between traffic on modem leased by $PROVIDER_A and traffic on that same modem an hour later leased by $PROVIDER_B. Also, does he, or anyone else, have any explanation why [insert favorite obvious big backbone] is missing from that list? I know most of the ASes I used to see as "big" are not listed. -- TTFN, patrick

MSN uses at least two dialup wholesale outfits. Earthlink uses their own modem banks in California, IIRC, and probably also in Atlanta since they bought Mindspring, and outsources to at least two other companies in other cities. SBC probably has its own dialups, but its Prodigy division used to use Splitrock for dialup access and may still use Splitrock.

He can't without access to logs. -- JustThe.net LLC - Steve "Web Dude" Sobol, CTO - sjsobol@JustThe.net Donate a portion of your monthly ISP bill to your favorite charity or non-profit organization! E-mail me for details.

Post-merger Earthlink uses a combination of outsourced modems and large aggregation POPs for dense regions, depending (obviously) on the financial layout for any given area. This isn't NDA info; any customer can generally find out whether they're dialing into one of the super-POPs or an outsource by looking at their own reverse, and/or asking support where the number leads to. -- *************************************************************************** Joel Baker System Administrator - lightbearer.com lucifer@lightbearer.com http://www.lightbearer.com/~lucifer
