It all depends on what you mean by “The Internet”. If you mean the  
current implementation then, yes, it is hitting a wall. But if you  
mean the end-to-end architecture then I would argue just the opposite  
– it’s now time to move to an end-to-end approach in which the  
relationships are entirely outside the network instead of within a  
temporary wrapper we call “The Internet”. What is a “carrier grade  
NAT” if we are doing our own networking and don’t rely on carriers?

For me the take-away is that it’s been over 25 years and it’s time we  
move on. We need to learn from the postal services which have been  
routing for 2500 years (give a take a thousand or so). If we separate  
the IP address into physical path/address and application-defined  
handle then we can take advantage of the relative stability of the  
physical infrastructure and shift the responsibility for maintaining  
end-to-end relationships to the applications – just as the post office  
does now.

We need to get off the train before we run out of track and start take  
responsibility for doing our own networking. I would argue that the  
point of the Internet architecture is that you solve problems at the  
edge rather than relying on carriers and operators.

I’ve sketched out some ideas in essays and as I’ve written that we  
need more research in using connectivity rather than in the network  
itself. Even if we weren’t facing the wall for IP we’re still not  
taking advantage of the common infrastructure but instead are still  
building a dedicated infrastructure for each application and service!  
It’s not just the redundancy of “broadband” but they very idea that  
cities have dedicated municipal networks and we have Wi-Fi networks  
and cellular networks and G-rated networks and safety-only networks  
and we still control our buildings and homes using wired logic. It is  
indeed to time to get our heads out of the networks and look around at  
what we can be doing with networking.
