[Ns-developers] customizable ns2 ? (ns-3 and future development)

[Adrian Sai-wah Tam]

Agree. Actually, as the project grows, I see NS2 becomes more and more
difficult for a beginner to study. I can see that if there is a student
who has a very in-depth knowledge on computer networks and C++
programming, he would also found it not easy to modify NS2 to implement
something he wants.

I know that it is not good to modify NS2 now, but for NS3, I believe we
should re-design the structure to make it more scalable. First thing I
believe we should do is to really implement a full-featured protocol
stack so that we can interface the simulator with the real network.
Second thing is, as Batov said, make it "customizable", so that we can
put in or move away some "modules" easily.

I quite appreciate the Linux kernel's module structure, which allows you
to add/remove some components in compile time *without modifying the
code*. However, do anyone has a plan for NS3 yet? Any architectural
decision made?
