[ns] pagePool/WebTraf - about parameters

["Sergio Andreozzi" <sergio.andreozzi@lut.fi>]

Hi everybody!

considering large-scale-web-traffic.tcl example,  could you please explain
me $objSize and $interObj meaning?
And what about avg_ and shape_ attributes?


.....

# Create sessions
$pool set-num-session $numSession
set launchTime 0
for {set i 0} {$i < $numSession} {incr i} {
	set numPage [$sessionSize value]
	puts "Session $i has $numPage pages"
	set interPage [new RandomVariable/Exponential]
	$interPage set avg_ 15
	set pageSize [new RandomVariable/Constant]
	$pageSize set val_ 1
	set interObj [new RandomVariable/Exponential]
	$interObj set avg_ 0.01
	set objSize [new RandomVariable/ParetoII]
	$objSize set avg_ 12
	$objSize set shape_ 1.2
	$pool create-session $i $numPage [expr $launchTime + 0.1] \
	$interPage $pageSize $interObj $objSize
	set launchTime [expr $launchTime + [$interSession value]]
}

........



Thanks,

	Sergio
