Alexander asked: #Excellent public studies of Internet traffic by protocol exist from NSFNet #times up to 2002 or 2003; we thank Odlyzko, Claffy et al for their work. # #However, has anyone else noticed a serious lack of data after the end of the #studies summarised in "Longitudinal study of Internet traffic 1998-2003", #Fomenkov, Keys, Moore & Claffy, 2003? (This has been discussed in the past, #I think.) All that seems to be available is vendor handwaving of the sort #Andy Odlyzko takes so much trouble to debunk; and that without any source #data. Recognizing that Internet2's traffic is likely significantly different than typical so-called tier-1 providers, you may still be interested in the weekly Internet2 Netflow reports available at: http://netflow.internet2.edu/weekly/ Regards, Joe
