   Now I'm engaged in the wired&wireless Diffserv experiment in ns2,but it always fail 
over wireless link, I searched the forum that had discussed before, 
one said ""ifqueue is different from the queue on link for wired networks""

When I traced that code , I found that before enque 
"codePt = policy.mark(pkt);" statement in dsPolicy.cc , the packet's data have 
something wrong in the src-dest pair, not the node id, 
  ex.ERROR: No Policy Table entry found for Source 8388608-Destination 4194304

  NS2 wireless diffserv can't work result from the wireless links,
so the srt-dst link pairs fails furthermore it can't found the policy table entry ?
Could someone kindly to help me out to solve the problem about the wireless Diffserv?
What kinds of modify should I take?
greatly thanks!
