Is there any publicly available statistics on the amount of exchange of data that transit through Internet between academic institutions? (e.g. X TB yearly from institution A to institution B)

3Including or excluding cat movies? (SCNR. I wonder how such a study could even be set up, with everyone using DropBox and similar services for large data sets. I'd therefore not trust such statistics overmuch.) – Stephan Kolassa Nov 16 '15 at 21:13

@StephanKolassa including cat movies. Yes, I don't expect data transiting via 3rd party applications to be easily countable: just focusing on direct connections (i.e. what network admins could see). – Franck Dernoncourt Nov 16 '15 at 21:21

2You should look at statistics from the different research networks that exist. For instance, the european GEANT network claims to transfer over 1000 Terabytes per day (!) https://en.wikipedia.org/wiki/G%C3%89ANT . The US has the Internet2 backbone which is mainly for academic institutions and I expect they are moving even more than 1000 Terabytes per day. – semi-extrinsic Nov 17 '15 at 09:11

In France, the network RENATER, which connect many universities, publish some statistics showing the live load of links:

Brazil has similar resources for the RNP: http://www.rnp.br/servicos/conectividade/trafego – Fábio Dias Nov 17 '15 at 14:58

This seems to be like Internet2 in the US. But I suspect that most data transfer happens over the public Internet, not over these research/educational networks. – ff524 Nov 17 '15 at 15:13

(Also, since these research/educational networks are widely used for experimenting with networks, they tend to carry a lot of "fake" data, which may or may not be useful to you in the context of this question.) – ff524 Nov 17 '15 at 15:16
