[ns] How to set FDL parameters in ONS-ns

[Ekularn Dhavarudha]

Dear all,

          I am using OBS Simulator on ns-allinone-2.28 and I don't know
how to configure the parameter Classifier/BaseClassifier  nfdl,
Classifier/BaseClassifier maxfdls, and Classifier/BaseClassifier
option. What are different between the nfdl and maxfdls, and what are
the relationship between them and the option? 

            I'm very confused and looking forward to your kind reply. 

Sincerly Yours, Ekularn Dhavarudha
