The packet is curious how many steps it needs to go.

For example, using the same routing diagram from the example above...

     |          
     |  +--+    
     A  |  C    
 F---|--|-E---+ 
     |  |  |  D 
     +B-+  +--+ 

...the packet would go:

6 steps down (including the first line at the top of the diagram).
3 steps right.
4 steps up.
3 steps right.
4 steps down.
3 steps right.
2 steps up.
13 steps left (including the F it stops on).
This would result in a total of 38 steps.
