Paper in nature on "Internet Tomography"

rafial writes "A group called CADIA has just published a paper in Nature that describes there work on " Internet Tomography." Essentially they are firing large numbers of pings trough the Internet and analysing the results to analyze topology and performance. Lots of neat pictures, and they are using FreeBSD to conduct their research! " Sweet looking stuff. Check it out.

What about MIDS

[phil reed]

What about the MIDS Internet Weather Report? This sort of thing has been running for ages. http://www3.mids.org/weather/

Only be as precise as you want...

[adamsc]

You don't have to give a hyper-accurate location. Just report the city. If you're still worried at that point, the black helicopters will chase you down before you can run far anyway...

Neat stuff

I was looking around at the stuff CAIDA has on their web site. Very cool. The java app that shows the network pipes is, for me, awesome. I was thinking that a really killer application would be a traceroute that would interact real-time with a graphical geographical representation of the pipes it goes through. Maybe with a text window below the graphic w/ the traceroute output. Too bad I can't code to save my life.

Well I'll be dipped in...

...pretty pictures, but the internet really does look like a cloud! or a clump of moss or some fractal generated by my screen saver.

I wonder if the software is available?
Are they accepting volunteers for additional "survey stations"?

Quick Question

[GreenPickles]

What is "rtt"?! (on the right side)

Cheops

[Paul Carver]

Cheops does something like this, although I found the display quickly became overwhelming.

Usenet Topology

Alone the same lines.. for usenet... based on usenet Path: headers

another cool pciture

[dumptruck]

here [bell-labs.com] is another cool picture of the internet

an xearth?

[eGabriel]

Back when I was a boy, we called them globes.

KC can do some amazing things with numbers

[MikeM]

KC (K. Claffy) was showing some of these pictures at an IETF last year and they were amazing then. One of the more interesting things was how pervasive (invasive?) Verio's networks were becoming.

She has also been giving reports at the IETF for several years on web cache performance at the IETF meetings. Finally someone is actually looking at real performance numbers on these networks....

Neat stuff

Actually, the Macintosh program WhatRoute has this function. Unfortunately, it doesn't seem to work very well, as the sever it gets the location data from is either slow or doesn't have info on many nodes, but when it *does* work, it's very cool.

Geography

[nb]

there is not much info available out there
to convert IP numbers to geographical locations...

unless everybody out there actually put
location information in their DNS records
(just the city the machine is located in
would be *loads* more useful than no info
at all).

more info from CAIDA about this (RFC 1876),
