I think the author may have made a mistake in some of the math. The frame size distribution plots are likely based on the number of frames, not the amount of data contained in said frames. The 1500 byte and other large frames should therefore account for the lion's share of the actual data transferred. Correcting this error will totally change the final two graphs.

Yes. But only the "AMS-IX traffic by packet size range" graph is wildly inaccurate. Ethernet frame overhead is per-packet and presumably right.

Ah yeah, that's probably true. According to some back of the envelope math, it seems like the distribution should be more like 5%, 1%, 1%, 3%, 50%, 39%, ignoring the first and last size bins.
