VoIP QoS monitoring using ns-3

[Eric Suhendro]

hello there, i'm new to NS-3 and going to monitor the QoS for VoIP using ns-3. i've built the topology, but i can't find the source files for monitoring QoS for VoIP, maybe some of you could hel me out of this ? :D
thanks before

Hi Eric,

What do you mean by monitoring QoS for VoIP. You have to define QoS metrics e.g. delay, jitter etc.

Some of these metrics can be measured using FlowMonitor class. There are examples using it and a lot of discussion in the mailing list.

Konstantinos

Hi Anthony, thanks for reply :D
do you mean my topology code ??

[Eric Suhendro]

Hi Konstantinos,
yes, that's what i want to measure : delay, jitter, packet loss. Yes, i could use FlowMonitor class to monitor them for VoIP system ??

[Konstantinos]

FlowMonitor measures network layer statistics e.g. the packet losses at network layer, does not count for retransmissions etc at MAC, end-to-end delay and jitter.
For example see this discussion in the mailing list https://groups.google.com/d/msg/ns-3-users/teE-cTfkV_Q/hkCeZDivXzQJ

[Anthony Faustine]

yes  sir

[Frank Wetzels]

Is there good QoS code out there?

Sorry for late reply.
i have used flow monitor, but an error occurs, i don't really understand where the error is about
the error that comes out.
I have uploaded the error picture and the code here.
I hope someone could help to solve this error. Thanks :D

[Eric Suhendro]

Hi Anthony, i have uploaded the code too in the previous code.

Instead of including only the flow-monitor-helper.h, try to include the complete flow-monitor-module.h
