For example if you have, say, a 2Mb modem --- which means that you have
2Mb in the updirection and, therefore at the same time, you have 2Mb in
the down direction (because you said that the modem is symmetrical).
There is NO way that you can make that same modem give you say 3Mb in
the updirection and 1Mb in the down direction. The hardware would never
allow it. Not BEEP nor TCP packet dropping or IP routing is going to
change that.
