What is NAM file in NS2?

What is NAM file in NS2?

NAM is a Tcl/TK based animation tool for viewing network simulation traces and real world packet traces. It supports topology layout, packet level animation, and various data inspection tools.It has a graphical interface, which can provide information such as number of packets drops at each link.

How do I run Nam?

Do the following:

  1. Create an output file.
  2. Activate the NAM trace feature in NS before running the simulation (this will tell NS to write NAM events outputs to the output file)
  3. Close output file at the end of the simulation run. Then you can run nam with the output file (as input file for nam)

How do I open a NAM file in Ubuntu?

How to Install Nam in NS2 Ubuntu

  1. System requirements.
  2. Open the terminal and verify the installed package.
  3. Execute the command.
  4. Source code for main file.
  5. Change the location.
  6. Execute/run the main tcl file : using the commnad ns.
  7. Open the trace file.
  8. Get the simulation.

Which file is used to visualize the simulation after executing in NS2?

NAM file is a separate program which is distributed with NS2 simulator to read an input file and draw the network events graphically. It is used to visualize the progression of packets through the Network.

What is FTP in NS2?

FTP will automatically control the traffic according to the throttle mechanism in TCP. The traffic flow of UDP must be colored red, and the traffic flow of TCP must be colored blue. The “CBR” is set to start at 0.1 sec and stop at 4.5 sec; the “FTP​​” is set to start at 0.5 sec and stop at 4.0 sec.

What is awk file in NS2?

AWK is a high level programming language which is used to process text files,named after its three orginal author’s name: A : Alfred Aho. W : Peter Weinberger. K : Brian Kernighan. AWK Scripts are very good in processing the data from the log (trace files) which we get from NS2.

What is Nam in Unix?

Nam is a Tcl/TK based animation tool for viewing network simulation traces and real world packet trace data. The first step to use nam is to produce the trace file. The trace file should contain topology information, e.g., nodes, links, as well as packet traces.

What are the 4 files on NS2 simulator?

The objective

  • This network consists of 4 nodes (n0, n1, n2, n3).
  • The duplex links between n0 and n2, and n1 and n2 have 2 Mbps of bandwidth and 10 ms of delay.
  • Each node uses a DropTail queue that has a maximum size of 10.

How to open a Nam file in ns2?

In here the trace data is flushed into the file by using command $ns flush-trace and then file is closed.Then,execution of nam file is done by using following command. The Extended Nam Editor is an editor that allows the graphical creation of ns2 scripts. It extends the basic Nam Editor with the following features:

What do you need to know about NS2?

It is a discreet event simulator targeted at networking research and provides substantial support for simulation of routing, multicast protocols and IP protocols, such as UDP, TCP, RTP and SRM over wired and wireless (local and satellite) networks. To view your network simulation traces made using ns-2, you’ll need Nam: Network Animator.

How do I run Nam animator in ns2?

How to run NS2: First you open a terminal in Linux and type the command ns It will show you % , it means NS2 is installed and working properly. How to run NAM: Open a terminal window and type nam, this will open NAM Animator. Execute the script using the ns command.

How can I check the installation of NS2?

You can check your installation by running a simple Tcl script. If you are a beginner to network simulation, you can find the explanation for the above script here. The ns-allinone-2.31 package is available here if needed.
