All network devices (being router or ATM switches or Ethernet switches)
receive the complete IP packet and have access to its content.
If the packet is in clear text, the network device has access to your
data: can read, can delete, can modify...
If the packet is encrypted end to end, the network device is assumed
not to get access to your data as long as your encryption is good enough.
It is even worse than what you may think because a bad talented guy
could modify the Internet routing table (injecting fake BGP information)
so that, e.g. the traffic from London to Paris will have to go first
to the bad router located in Melbourne.
