Dear ns-users,
here I want to thank everyone that help me till now in my project.my thesis is
progressing.( it is about call admission control in diffserv )
now again i have some questions and i hope that you answer to me.
1- what kind of traffic is used for video conference in ns. for example for
VOIP we use from Exponential traffic. i guess that i should use from trace
files of real traffic. what's yr idea?
2-for VOIP traffic i calculated PLR but in xgraph, i saw strange behavior.
PLR reaches to 48% and suddenly decreases to -48% and gradually again increases
to 18% and this behavior repeats with different PLR. i can't understand why.
and also PLR is very high. is it normal?
please kindly answer to me.
Thank you in advance.
Best regards,
Elahe
