giving me this error message.

[ns] DiffServ in NS
Hi I have seen a patch on somebody's web page that enables this feature. If I find it, I will let you know. In any case, if you are not afraid of coding, then take a look dsPolicy.cc, PolicyClassifier::mark() does the marking based on the policy and policer entries. You can extend it as you want. Sincerely, Alexander Sayenko (PhD) Assistant Telecommunication laboratory, MIT department University of Jyvaskyla, Finland Hello all, I need to do flow classification based on sourcedest port ID and not node ID as it is proposed in the DiffServ module provided within NS. Do you know a simple way to achieve flow classification using sourcedest port ID ? Best regards, Julien. -- Internal Virus Database is out-of-date. Checked by AVG Free Edition.

[ns] Sorely confused on setdest command
Hi, I've managed to solve my problem I had yesterday and now I got wireless nodes communicating with wired nodes :) Now I want my wireless nodes to move around. I am confused as to where the X and Y coordinates translate to with relevance to the node for setdest command. It seems to bound the X and Y values to (0,range of my topology grid). It also seems to correspond to the actual X,Y values displayed in nam. I am very confused on the movement command, for example, on a 500x500 topology, $ns at 4.5 $mobile(1) setdest 500 499 20 throws an error while $ns at 4.5 $mobile(1) setdest 499 499 20 does not. I also cannot have negative values either. I would simply like to have the X, Y values go to the same position as specifying node X_ and Y_ values for display purposes. I have read the manaul on this part and it has not helped. To me it appears it sets the topology grid in the first quadrant with 0,0 as the bottom left corner of the square. Could someone please shed light on node movement? Thank you

2) That is because your environment variable is not setting properly.
a) you can change your environment variable
