How do I run ns?
- Write OTCL Program. In ns2,we use object oriented tool command language as front end language or simply to write programs to generate a network scenario.
- Run program in Terminal. To run the program, open terminal window from accessories->terminal or search on dash home.
- Analyse trace file using awk scripts.

How run NS2 program in Linux?
Running a simple simulation
- Paste the following code in a file simple.tcl: #Create a simulator object. set ns [new Simulator] #Define different colors for data flows (for NAM) $ns color 1 Blue. $ns color 2 Red.
- Run the simulation from the terminal using ns-2: ns simple.tcl.
- Click on the play button to start the simulation:
What is TCP agent?
A “tcp” agent is attached to n0, and a connection is established to a tcp “sink” agent attached to n3. As default, the maximum size of a packet that a “tcp” agent can generate is 1KByte. A tcp “sink” agent generates and sends ACK packets to the sender (tcp agent) and frees the received packets.
What is FTP in NS2?
Description. In wired network, nodes communicate using the communication model that consists of Transport Control Protocol (TCP) agent, TCPSink agent, and File Transfer Protocol (FTP) application. The sender node is attached to the TCP agent while the receiver node is attached to the TCPSink agent.
