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
