[LENA] Access to the EPS Radiobearer Transmission Queue Size

[Hamed Samie]

Hi experts,

I am interested to have access to the Transmission Queue Size of a EPS radio bearer. I already asked a question similarly to this before and as Marco explained me the Queue size is not in MAC layer  and is in RLC layer  (https://groups.google.com/forum/#!searchin/ns-3-users/hamed/ns-3-users/xprX1DzDS1A/W46lEsrZCgAJ).

But as I am really new in NS-3, I was wondering anybody can help me to make this access easily? For example we take the Lena-Simple.ccp as the reference to work. The radio bearer is defined in the RED color. So I want to have the access to "txQueueSize" variable.

I appreciate your help
Cheers

Hi Hamed,

As far as I understand it, Marco's reply in your other query applies here as well.

To access the Queue you need to look at the RLC layer.

Please in the future attach the code as a file, not inline with your message.

Regards,

K.

Thanks Konstantinos for your reply. I will attach the file next time .

I am working on that but the exact code (line) is hard for me to write and this is why I wrote the question.

Cheers
Hamed

Dear Konstantinos,

After working on this issue, I updated my question. I appreciate if you can look at that (https://groups.google.com/forum/#!topic/ns-3-users/sV1-pIpkF3w)

Thanks

Hamed
