Is anyone aware of recent by-protocol traffic data in the public domain?

#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

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:
