I have to simulate DCCP and UDP on NS2 , for my presentation and showing the differences in throughput, delay, and jitter. I want to know that NS 2.35 standalone supports DCCP simulation, do I have to write any code for this simulation?
I am new to NS2 n linux platform.
Help is appreciated.
If you use Ubuntu (anything up to 14.04, the current release), you can install ns2 by the command
sudo apt-get install ns2
(optionally add ns2-doc and ns2-examples to the end of that command).
However, ns2 is deprecated - you are probably better off using one of the more modern simulators such as ns3, omnet++ etc.
Ubuntu is best choice but lookout for packages like Xgraph which may not readily available under Ubuntu, which you have to install separately.
For plotting ur results Gnuplot is the best as compared to the Xgraph and getting any of these packages in very easy on ubuntu.
@Peter Breuer as i mentioned that i want to show simulation of two transport layer protocol .
@Claudio de Farias : will you please elaborate?
@Daniel Franklin & @Ranjana Pathak : i have successfully installed NS2 on 14.4 . but if i use Omnet++ , do i still have to write scripts?
I have no idea of writing scripts.
@Pablo Gil > Thanks , trying to find a better one that doesnt need any scripting.
@ Peter Breuer : i dont care abt the platform,I just wanted to knw which OS is best to install NS2 , i really dont have to do anything else with the OS , except this Simulation i wrote abt ,
I have installed NS2 on Ubuntu 14.04 and seems to work ok.
now im working for any prewritten script that helps me to show the simulation difference between DCCP and UDP on packet/data transfer.
still im looking for some useful scripts.
Thanks :)
Your last post is very informative for me as I am new to NS , and this Linux environment. ,
@ Peter Breuer you are right , may be I was confused abt platform thing.and im doing some research while asking question but this is true that i dont get it all.
I will check the example today.
There are already many answers and from my experience I would also bet for Ubuntu. Concerning how to make graphics I would point out Matlab. If you customize your opwn traces (output in plain text), you can use Matlab to process them and make the graphs. On the other hand, if it is your first contact with NS and you plan to continue using it, you should consider using NS3 (it also implements DCCP and UPD, of course). The learning curve of NS3 is not so steep and it is clearly an evolution of NS2 (same developers). In NS3 you can avoid writting scripts since you can configure the scenarios directly in C++. Hope it is useful.
@Luis Diez Thanks for Sharing, but Matlab doesnt support Transport Layer protocols as far as I know. the idea of using NS3 can be useful but i went through a documents it says that NS3 doesnt include DCCP protocol.
please see the attachment.
@Kamran Ghani sorry for the misunderstanding. What I meant regarding using Matlab is that you can use it (offline) for drawing the graphs, in the same way as Gnuplot. Concerning NS3, you are totally right, from a quick look I thought NS3 supports DCCP but it doesn't natively. Nevertheless, what made me think it does is the fact that NS3-DCE (Direct Code Execution) [0] has linux-dccp sockets [1]. I have not espererience with DCE and maybe it adds more unnecessary complexity to youur work. If you are interested, here [2] is the DCE current tutorial, it is tested on Ubuntu, Fedora and CentOS.

@Luis Diez Thank you for ur advice , Now I am working on it as i have to present it within 2 weeks time.
Hi Kamran, I like to suggest to you that NS-3 is an improved version of NS-2. From experience, it is less tidious to work with. in NS-2 you are required to work with C/C++, TCL,TK, etc but NS-3 you are limited to C/C++. Since you are are just coming into ns-2 why not consider to learn ns-3 and with it rather than ns-2. I wish you the best.
i have installed on Ubuntu 14.04 ,32 bit but NAM is not working, it say some segmentation fault , CORE DUMPED . although NS is executing the sample tcls.
Hello Kamran Ghani. I understand you are using ns2.35 (last release I can see). As you must already know, nam is optional so you can still use NS2 without it. In fact, when I worked with NS2 I didn't find NAM useful at all, just as a visualization tool (someone else might disagree with this!). Nevertheless, in the NS2 web site [1] you can find the list of different "pieces" you need to get installed in order to everything works correctly. You may try to install one-by-one instead of using the all-in-one tarball and then check if everything gets installed. I don't think Ubuntu14.04 should have any problem with NS2 but you might need old version of libraries as the last release of NS2 is of 2011. Good luck.

NS2 can be installed on any plot form like Ubuntu, Kubuntu, Linux Mint... In addition to NS2, xgraph also has to be installed...
I have read that the Ubuntu platform is the most compatible for Steam
Why try ns3 on Ubuntu? Ns3 is an improved version of ns2. I used ns2 extensively but recently i found ns3 a better option at leat for begineers.
Ubuntu is the best platform to install ns2, and to me nam is not necessary for working with ns2, is just a visualization file.
If you are working with fiber optics networks it is better to use NCTU-NS under Fedora
