[ns] How to use RandomVariable to simulate traffic resource?
Hi, I know that we can use the TCL as below to simulate the traffic. set rtp_down($i) [new Application/Traffic/Exponential] $rtp_down($i) set packetSize_ 20 $rtp_down($i) set burst_time_ 352ms $rtp_down($i) set idle_time_ 650ms $rtp_down($i) set rate_ 8kb But how to use Random Variable to simulate traffic resource?

[ns] About add new RandomVariable. Help me!!
Hi everyone
I have added a new random variable "weibull" into ns2 by
example and have modified rancar.cc , ranvar.h and rng.h.
There was no error message after after compiling it
But I ran an example that occurred an error massage as below. What steps did
I forget or which file should be modified?
.
Does any one can help me?

Hi,
I have some questions about http simulation
First, what is the definition of ranvar-main-age. Does it mean the time for
the server to renovate a page?
Second, when I coded as below, the trace file is simply to understand.
But after I coded the mainsize by random variables as below, the trace file
became hardly to understand. Please help me..
TCL:
