ARPANET always had adaptive routing, and it was 
pretty good for the job for a while.  Later, the 
old ARPANET "distance vector" routing was 
replaced by the new ARPANET "link state" 
routing.  These routing algorithms *did* work 
around damage or other changes to the 
"environment", i.e., phone lines and packet 
switching going up and down, changes to the 
network configuration of phone lines and 
packet-switch sites, etc.  As things moved beyond 
the ARPANET, i.e., the Internet came into being 
and expanded, lots more routing work happened, as I remember.
