Re: [ns] Performance enhancing proxies

[Joseph Ishac <jishac@grc.nasa.gov>]

For spoofing, we used the 'trace-callback' in NS (a feature which allows you to
perform a routine for each line in a trace).  

Our constraints were that the spoofer needs to forward only unique data packets
and must not send data out of order.  The callback routine that we used is
attached (although not very well documented :)
