I want to study routing protocols and SCTP communication in a hybrid network mainly for reliability and QoS demands. >From what you write, it would probably be best to start with ns-2? > For ns-3, there is no code available yet, but it appears that a group > may post some code for SCTP in ns-3 shortly; please review this > thread: https://groups.google.com/forum/#!topic/ns-3-users/SfJ8cLXoXhA Thanks for the link. Sounds promising! I'm trying to register without a Google account. It seems that I have managed to subscribe to the ns-3-users Google groups. But I will have to wait for another mail of the "Sctp based Lte Handover in Epc" thread to be able to answer it. But for the moment I will play with both versions... > There is also the ns-3 DCE kernel code framework; since SCTP is in > the Linux kernel, one might be able to reuse this code (although I'm > not sure whether in your use case it would be suitable).

Hmm, unfortunately I think I won't be able to do that, I'm on quite tight schedule. > In general, all things being somewhat equal, you will probably find > more help on the lists when using ns-3, since it is actively > maintained. On the other hand there may be more documentation on ns-2? Beside the main documentation, I found a lot of ns-2 tutorials. This is also the case for ns-3, but the missing SCTP is the reason why I didn't already go for ns-3... > You mentioned needs for a number of other models: Ethernet, Fiber, > WiFi, ZigBee, PLC, GPRS.

To be honest, I haven't looked at ns closely, but I suppose I will be able to parametrize a new connection type or some kind of scenarion where nodes fail and recover. > Given all of this, probably it makes sense to try both out (existing > ns-2, and ns-3 once the SCTP code becomes available). I think, it probably won't hurt to directly contact Madan. I will wait and see what he anserws to your post from today... Thanks again Ramon
