Here's an example to show what I mean:
Let's say you're planning a road trip from Los Angeles to Halifax, which is quite some distance. You look at a map and can see highways (connections) that intersect at cities (routers) and plan the shortest route through a certain set of cities.
Now, afaik nobody - not even Google - has completed a near-complete map of all the connections in the whole Internet, which change regularly anyway. How, then, do packets know where to go? Or, more precisely, how does one router know where to send it next?
Thanks,
Chris
