Re: [ns] delaySamp_ object and Delay samples
-
Yes, I did.
I had the same problem and the same day I posted the question, I also found
a solution to this matter and
to another one concerning using monitor objects to measure average queue
length in a wireline network.
I have posted a thread to ns-users mailing list concerning the description
of both problems. You can find it here:
http://mailman.isi.edu/pipermail/ns-users/2006-August/056736.html
I hope that I have answered your question.
Kind Regards,
Renata.

Subject: Re: [ns] delaySamp_ object and Delay samples
Hi Filippos,
Did you solve your problem? Can you help me?
I'm trying to get Delay Samples from monitor-queue, with these commands:
set qm [$ns monitor-queue $n1 $n2 $qt 0.5]
set integratorObjectDelay [$qm get-delay-samples]
set delayfila [$integratorObjectDelay set delaySamp_]
but when I run, I get the error:
ns: queueLog: invalid command name
while executing
$integratorObjectDelay get delaySamp_
(procedure queueLog line 20)
invoked from within
queueLog
According to NS DOC, the object it returns is delaySamp_.
Any clue!?

In the manual it states that this object can be used to measure queue
delays
(page 76 of ns-manual).
It has two methods:
$queuemonitor get-delay-samples, which says it returns a Samples object
delaySamp_ to record delays about queues and
$queuemonitor set-delay-samples delaySamp_, is to set up the delay
samples
object to record delay statistics about queues. Also, it states that
delaySamp_ is a handle to a samples object, which must have been
previously
created (supposedly with the get-delay-samples method above).
However I have the following code:
#Setting a queue-monitor object for a specific queue
set monitorQueue2_3 [$simulation monitor-queue $node2 $node3 stdout]
#Setting the integrator for the average queue size - this works ok
set integratorObject [$monitorQueue2_3 get-pkts-integrator]
#using the get-delay-samples method of the queuemonitor object to get
a
delay samples
set delaySamples [$monitorQueue2_3 get-delay-samples]
#using the set-delay-samples method on, supposedly, the returned
object to
set-it up,
#according to the manual
$monitorQueue2_3 set-delay-samples delaySamples
more code
When I simulate the tcl code I get the following error:
(_o59 cmd line 1)
invoked from within
_o59 cmd set-delay-samples delaySamples
invoked from within
catch $self cmd $args ret
invoked from within
if [catch $self cmd $args ret] {

(procedure _o59 line 2)
(SplitObject unknown line 2)
invoked from within
$monitorQueue2_3 set-delay-samples delaySamples
(file simulation-Class-AverageQueue.tcl line 80)
What Could be the cause of this? I use ddd as my debugger and I have
come to
the conclusion that the get-delay-samples method does not return
anything,
since
the delaySamp_ object is initialized to NULL upon initialization of the
queuemonitor object.
The code is in the queue-monitor.cc file in ns-directory/tools/
How can one use the delaySamp_ objects of queuemonitor to measure queue
delays?
Am I correct, or I am erroneously using these methods?
Any help would be appreciated.
