I want to model how traffic will flow on real networks (not just the internet, also, say, Intel's internal LAN).

Is there a place I can get real network topologies data I can use?

  • $\begingroup$ A question when you say "network" - that word means many things. Do you mean anything that might be defined as a network (for example, the social contacts of an entire city) or do you mean a network of computers? $\endgroup$

  • $\begingroup$ @EpiGrad indeed a network of computers. LAN, or WAN, etc. $\endgroup$

In addition to the source listed by JohnRos, the association for social network analysis (INSNA) have a lot of data (sometimes the datasets are missing, though). Another source might be Tore Opsahl's website (the airline data are a good candidate, as the forum data are). Finally, Mark Newman's page is another source. If you have an interest in open source software, FLOSSmole might be another place to fish for large network datasets (but I do not know if there is information about flow in there). This thread gives a lot of other potential sources

Stanford Large Network Dataset Collection. Which is part of the Stanford Network Analysis Project, SNAP.

    $\begingroup$ Can you point me, which of the dataset there relates to network (eg ethernet, LAN, WAN) topology? I don't see anything there. $\endgroup$

  • $\begingroup$ @Elazar: SNAP is a wonderful resource, but the reason you don't find any such data sets there is because there aren't any. (There are a few web graphs. The autonomous systems ones may come close, but I suspect not quite what you're looking for.) $\endgroup$
