Using this analogy, isn't a suitcase roughly equivalent to a packet? It's tagged with source/destination, and basically standardised so the routing gear doesn't need to care about the specific items you are routing.

You know, I think the analogy might actually be the wrong way round....

The analogy goes even further!

At certain points along a route, deep packet inspection is performed, and some packets will be modified to remove contents that the country in question does not want to route.
