Nick,

The variables you mentioned, shift_ and mask_, are for two reasons:

1) NS currently stores port number and address into one 32-bit
   variable, of which the least significant eight bits are for port.
   The rest is for node address.

2) If ns is running in hierarchical mode, then it needs a set of
   shift and mask for each level of hierarchy.
