Passive optical network simulation

[ssz]

hello,
i want to simulate a mac protocol for passive optical network. there
will be a central office and an user having three different service
connected through an optical line terminal (OLT). Are Qos, throughput
and delay all possible to simulate in ns3? can i simulate optical
network in ns3 ? i m totally novice using ns3. so i need your help to
know this.
thank you
SSZ

We don't have any models for optical communications yet. Feel free to contribute one though.

 

thank you

I need to implement or integrate the XGPON model in NS3.. here is the model link..

I am new to NS3

http://sourceforge.net/projects/xgpon4ns3/

Hi Ghufran,

Please do not make the same question in different threads. 

Have you read the documentation of NS-3 and that of the XGPON ?

http://www.nsnam.org/documentation/

Particularly the part of creating a new module in NS-3 may be helpful. 

http://www.nsnam.org/docs/manual/html/support.html

In addition, you might need to change some existing code of ns-3 (as far as I can see the ipv4-l3-protocol.cc has been updated).

There XGPON module you posted, has example code inside and manual inside.

I am new to Ns3. I have just installed Ns3 and dont know how to run that project any manuals for learning Ns3 would be helpful

I just posted the link in my previous answer..

http://www.nsnam.org/documentation/

There is a tutorial, videos and other documents

Oh, look, ns-3 does have a website. And a documentation section too !

http://www.nsnam.org/documentation/

Seriously, the best thing, if you're new to ns-3 is to read the tutorial and at least have a look at the manual. Then, if you're particularly interested in that module, read the manual in the link you cited.

Of course you can ask any question you like in this mailing list, but I'd strongly suggest to not try to "jump-start" without the tutorials.

Cheers,

T.

I need some error while adding a new module to NS3, I am recieving error failed to find header files when i use $ ./waf and when I use ./waf configure I get Could not find a task generator for the name 'ns3-gppon

Hi Ghufran,

My name is Pedro Alvarez and I am one of the developers of the XG-PON model. I am really glad to hear people are starting to use it. I can help you a bit if you are having some trouble, but please try to be more clear to what is the issue.
What exactly have you tried, what system are you using and what exactly is the error message?

Regards,
Pedro

Hey Pedro.. I really need to contact you.. I am facing difficulties while installing xgpon model to Ns3, although I have followed instructions as directed in the manual. please brief me. contact me at ghuf...@gmail.com

[ghufran siddiqui]

hi Pedro, 

Please describe me how to evaluate that XG-PON model and which script file i have to copy in ns3-dev and what to do next.. I am not getting it please help me

hi sir happy to message you.. how i can create a coding for  new DBA algorithm other than GIANT ..EBU and XGaint.. second i want to know about integration of xgpon with other module which is existing in ns3 like LTE and WIFi..pls help me to find out these doubts

Hi Pedro,

I'm nadia kalsoom and trying to find delay and packet loss ratio for XG-PON model. by using flow-monitor, got the following packet loss ratio, which is very high. can you guide me to how to find the reason behind this high packet loss ratio? because i didn't find this behavior with XG-PON v1. or you may suggest me a good material for this.
