[ns] relation between route_ and slot_

[Antoine Bagula <bagula@cs.sun.ac.za>]

Dear LLoyd,

I am looking for a logical relation between the structures route_
used by the C++ compute_routes in route.cc and the slot array slot_
used in all the classifiers(see classifier.cc). In my understanding route_
is a global routing table containing next hops for arriving packets at each
node. In the NS classifiers upon reception of a packet a function classify() 
is called to find an index for the slot_ array where the packet will be 
forwarded. Can you please explain me how these two arrays are related.

Thanks 

Antoine B.
