I tried this with a recent snapshot (ns 2.1b7-snapshot-20000720) and
found it straightforward to get this diffserv code working and pass
the supplied regression testing, matching the output described in the
Nortel tcl/ex/README.

Make the simple changes as outlined in the diffs below, and you're
compatible with ns 2.1b6a, the last ns 'release'.

that zip file is quite pc-centric (do make sure you unpack
it in a new empty directory, or you'll fill your current
directory with junk...); use dos2unix to strip ^Ms etc.

cheers,

isn't a capital letter in a filename a cross-platform nono?
