A while back, I posted a question to this list: http://www.merit.edu/mail.archives/nanog/2002-01/msg00009.html So, I've still been on the lookout for traffic graphs. I know that many times the mrtg graphs can be misleading and downright wrong at many times, but I still think it's neat to be able to see how much traffic is flowing across various links. But, it would be even better to know what the aggregate flow of traffic across the Internet was at any given time. I know it seems impossible to calculate such a measurement... For example, if one looks at exchange point stats, like linx.net, you can see that at any given moment in time, that facility is exchanging ~15 Gb/s. Could one add all of the aggregates of the exchange points together? Would it even make sense to do so? Is CAIDA working on some way to measure aggregate traffic flow on the Internet? Something like the following (except that it would be representative of the entire Internet, not just Abilene) would be really neat. http://monon.uits.iupui.edu/abilene/total/total-bits.html I have done quite a bit of googling, but have not been able to find any relevant information.
