qos routing



Hi All,

	My research interests are on QoS-based routing, so I'm using 
ns to support this. The question I'll make is very specific, I hope 
someone can help me. 

	My problem is as follows. I modified the DV dynamic routing 
scheme in ns, which is implemented in otcl. My intention was to mesure 
the efficiency of the new possibles routing schemes indirectly, by 
means of the quantity of packets lost when a link goes down and the 
routing algorithm has to recalculate the routes. Best algorithms would
adapt faster, and the packet loss would be smaller.
	But what I observed is that the processing put into the 
procedure compute-routes in DV has no influence in the packet loss. I
couldn't explain why. Fact: the routine $ns now returns the same 
time in the begining and at the end of DV compute-routes.
	Can anyine give me any tips of what is happening? Your help is
very appreciated.

	Thanks,

	LuisH
