A proper emulation of them is in the ns2 code. It has been a persistent feature request, to add support to some Linux rate shaper to properly emulate PowerBoost, but no funding ever arrived. Basically you get 10 extra megabytes above the base rate at whatever rate the line can sustain before it settles back to the base rate. You can also see that as presently implemented, at least on a short RTT path, the feature does not prevent bufferbloat. http://snapon.lab.bufferbloat.net/~cero2/jimreisert/results.html I'd like a faster, less cpu intense rate shaper than sch_htb in general, and powerboost emulation would be nice.
