ns (from network simulator) is a name for series of discrete event network simulators, specifically ns-1, ns-2 and ns-3. These simulators are used in the simulation of networking protocols and especially so for ad-hoc networks.
ns-3 is built using C++ and Python.
It includes four steps:
ns began development in 1989 as a variant of the REAL network simulator and it is currently maintained by volunteers. Long-running contributions have also come from Sun Microsystems and the UCB Daedelus and Carnegie Mellon Monarch projects
ns-2 was built in C++ and provides a simulation interface through OTcl, an object-oriented dialect of Tcl. The user describes a network topology by writing OTcl scripts, and then the main ns-2 program simulates that topology with specified parameters. It runs on Linux, FreeBSD, Solaris and Mac OS X. It is licensed for use under version 2 of the GNU General Public License.
On February 22, 2005 Tom Henderson made a post on ns-developers mailing list saying We intend to have some discussions on how some of ns-2 might be either refactored or forked as part of a future development effort (in parallel, for now, with maintenance of the existing code tree).
Write what you know
So they say all I know is I don't know what to write
Or the right way to write it
This is big lady don't screw it up
This is not some little vaudeville I'm reviewing.
Poor little kids versus rich greedy sour pusses
Ha, it's a cinch
It could practically write itself
And let's pray it does cause as I may have mentioned
I have no clue what I'm doing.
Am I insane this is what I've been waiting for
Well that plus the screaming of ten angry editors.
A girl? It's a girl. How the hell? Is that even legal?
Look just go and get her.
Not only that there's a story behind the story
Thousands of children exploited
Invisible
Speak up take a stand
And there's someone to write about it.
That's how things get better.
Give life's little guys some ink
And when it dries just watch what happens.
Those kids will live and breathe right on the page
And once they're center stage
You watch what happens.
And who's there with her camera and her pen
As boys turn into men
They'll storm the gates
And then just watch what happens when they do.
*scream*
Picture a handsome heroicly charismatic
Plain spoken know-nothing
Skirt chasing cocky little son of a-
Lie down with dogs and you wake up with
A raise and a promotion.
So he's a flirt, a complete ego maniac
The fact is he's also the face of the strike
What a face
Face the fact that's a face that could save us all from
sinking in the ocean.
Like someone said power tends to corrupt
And absolute power
Wait wait corrupts absolutely
That is genius!
But give me some time
I'll be twice as good as that six months from never.
Just look around at the world we're inheriting
And think of the one we'll create
Their mistake is they got old
That is not a mistake we'll be making
No sir we'll stay young forever!
Give those kids and me the brand new century
And watch what happens.
It's David and Goliath do or die
The fight is on
And I can't watch what happens.
But all I know is
Nothing happens if you just give in.
It can't be any worse than how it's been
And it just so happens that we just might win
So whatever happens
