FreeBSD (www.freebsd.org) includes a 'dummynet' device which can drop
packets, introduce delays and restrict bandwidth.  It can't corrupt
data packets - though there's no reason why you couldn't add this
functionality.

There are various references to it and its use in
http://info.iet.unipi.it/~luigi/research.html and the man pages are
