See http://www.antd.nist.gov/itg/nistnet/ for a complete Linux based
WAN emulator.
Another alternative is the queueing framework in 2.1, which has modules
for traffic shaping, classifying packets etc. (see linux/net/sched/*.c)
Nistnet is more aimed at protocol testing, while the second is for
production use.
