In these pages I describe ns version 2. Version 1 is different, though
there is a backwards compatibility library in version 2.
The purpose of these pages is to make it easier for new ns users to use
ns and nam, to create their own simulation scenarios for these tools and
to eventually add new functionality to ns. I have found the existing
documentation to be rather useful for users who already know the basic
features of ns, while it can be a bit tedious for new users to extract
the necessary information from the manuals and the example scripts. In
this tutorial I will lead you through some simple examples, introducing
more and more new features as we go along. The ultimate goal is that after
a short time you are able to efficiently use ns and to find any further
information you might need in the existing documentation. For this purpose
I will also try to tell you where I found the information in this tutorial
myself, so you not only learn how to use ns, but also how to use its
documentation.
The web is probably the best medium for a tutorial like this, because it's
not only possible to add pictures (or even animations) for the examples,
but you can also directly download the examples if you don't have the time
for typing them in yourself (though I would suggest doing that at least
for the first few examples). I chose a frame-oriented design for these
pages, since it makes them easier to navigate. If you find that the left
frame with the contents takes up too much room or if you just don't like
frames, you can switch to a frameless version.
Please understand that I can not give you a full reference manual for ns
here, or a full Tcl/C++ tutorial, and that in a simple tutorial like this
I can not help you with special problems like installation problems. There
are better sources for that which I am going to list in Section II.
If you have any suggestions, find any bugs or problems, have any comments
and also if you have any new (well-documented) examples that could be added
here, please send email to
ns-users mailing list.
