Re: Internet diameter?

Hi, Does anybody have more or less recent data on the average, median and maximum diameter (ip hop count) of the Internet? First, to give some hints regarding the initial question: A year ago I did some analysis based on Caida's routed /24 topology data set

Re: Internet diameter?

Hi William, We don’t have the number sitting around, but you can get a pretty good feel by clicking through a few of the ark monitors (http://www.caida.org/projects/ark/locations). Click on “data” to the right of each monitor. Bradley On Nov 22, 2018, at 7:55 AM, William Herrin wrote: >

It's not exactly a measurement of "user to content" but CAIDA has swarms of Raspberry Pi nodes all over the world, that constantly measure... well, a lot of things, but they continually also monitor traceroute paths to each other. If you're looking for a "average length from any one node to any

RE: Internet diameter?

To get back to the original question regarding the "diameter" of the Internet, it would appear to me that we are easily looking at about 30 to 40 hops just within North America -- and easily double that to reach the rest of the Internet outside of North America. Of course, the "Top 5

This begs the question, which is more meaningful a metric, AS-path or hop count? Many networks have a large number of routers but the packets don’t stay in them very long. -Ben. > On Nov 21, 2018, at 8:10 PM, Bryce Wilson wrote: > > I don’t have any hard statistics but I notice that on a

Re: Internet diameter?

I don’t have any hard statistics but I notice that on a majority of ASs on bgp.he.net , the average AS path length is between 4 and 5. As for the average number of hops, it clearly depends on what type of traffic and many ASNs have more than one router. Going on my own

I'd argue that's just content (though admittedly a lot of it). You can't cache, e.g., a SIP trunk, and offices which need to connect to each other can't cache one another in a CDN either. On Wed, Nov 21, 2018, 10:29 PM Aaron1 Considering 40% of the “internet” is sitting in my backyard in cdn >

Considering 40% of the “internet” is sitting in my backyard in cdn caching, I’d say the perceived diameter for that content is 3 or 4 hops. ;) ...but something tells me that isn’t they response you were seeking... ... but seriously it is interesting that with local caching that much of
