Dayumn! Nice illustration! Keep them coming!

It reminded me of a great book on networking:
Computer networking a top-down approach

Exactly correct view, Thanks.

In the early days of TCP and small slow bandwidth, we saw congestion 60% or more with many hop counts >30.

The Tcp layer would time out based solely on retries.

Customers would complain about speed which turned out to be 10 routers on first leg.

We also saw unreliable DNS services back then. That problem took many businesses down for long periods of time.

Since then network infrastructure has improved so much it's astounding.

I remember doing some work in NYC. Their hop counts were 35 on average.

Did you create this diagram? In the top left, it says @manekimekko or something, but it's hard to read, and I'm trying to find the original author.

I'm an the original author. @manekinekko is my Twitter handle. How can I help?

OK great work. I just saw that it's being shared everywhere, but people don't mention the original author. I'd like to share it too, and now I can link back to your page. Thanks!

I've been wanting to create a similar post with all the details you beautifully provided in your diagram. This is amazing, I see no point writing a second post. I appreciate the time and effort you put into this. Thank you.

The great thing non mentioned in the infographics is that all the technology involved at each step is free, non-proprietary and accessible to everyone. I don't know if there is any patent involved either.
