Hi, Shahram:

I suppose that so far only qualitative PHBs have been defined. When we consider
a quantitative PHB, PHB with Dynamic packet state might be a solution. You can 
take a look at the following ID for detail.

" Per Hop Behaviors Based on Dynamic Packet State " 
[draft-stoica-diffserv-dps-00.txt]  

go to http://www.cs.cmu.edu/~istoica/DPS/.

regards,

Gang
