No. There was an early suggestion to add a "receiver-controlled" mode to
diffserv, but there was an explicit choice *not* to make the basic
diffserv architecture dependent on level 2 in any way.

What do you mean by "does not work"?

Hi Brian,
When i apply my code for wired network, it runs.  
Let me explain detailed for wireless network; firstly i have created a
script code without any queueing management and i have seen the number of
dropped packets in my topology. But when i apply diffserv for this wireless
network, the number of dropped packets has not been changed, that is,
applying diffserv to my wireless scenerio has not affect my scnerio by means
of the number of dropped packets. 
I attach my tcl code. wireless_diff1_not.tcl is the code without diffserv
and wireless_diff1.tcl is the code with diffserv. Am i doing something
wrong?
Thanks in advance
Semra Yilmaz
