It provides substantial support to simulate bunch of protocols like TCP, FTP, UDP, https and DSR. We also have started our service in a goal to serve the budding students and scholars. ONLINE NS2 SIMULATOR        Online NS2 Simulatoris our online service started for students, who feels to gain useful information through web. Similarly, users are responsible for verifying for themselves that Students work with us due to our privacy and confidentiality service. It is an It uses TCL as its scripting language OTcl adds object orientation to TCL. To terminate the finish procedure at particular time, use the following commands: This is an overall step to write any script in NS2. The C++ ns-3 is free software, licensed under the GNU GPLv2 license, and is publicly available for research, development, and use. This was known as the LBNL Network Simulator, and derived in 1989 from an earlier simulator known as REAL by S. Keshav. 1. Network Simulator 2 is focused for modeling network protocols From Ns2 we also can evolve fundamentals of network performance A package of tools that simulates networks behavior Ns2 Tutorial for engineers.For Creating latest ad hoc network,wireless sensor network simulations using ns-2 contact us also for best implementation.Our staff helps in clearing all your doubts with best effort.Get guidance also for better implementation of ns-2 projects.. What is Ns2? C++ is used to define the internal mechanism in NS2. This is used to connect traffic generator to see the packet transmission. Ns is a discrete event simulator targeted at networking research. Ns2 Tutorial is a discrete event simulator also for networking research and also work at packet level research. substantially over the past few years. It can set up packet traffic related to internet and measure a variety of parameters. It is no longer developed nor maintained. In the process of developing ns-3, it was decided to completely abandon backward-compatibility with ns-2. To store the result, first we need to open the files. Commands for opening the files is given as: First line Open result.dat will open the file and write it to W. Here, we have used “finish” as an assignment variable. Online NS2 Simulator is our online service started for students, who feels to gain useful information through web. Other simulator such as opnet, omnet, and NS3 and more ensure graphical user interface to provide result. Development of ns-3 began in July 2006. ns-3 is built using C++ and Python with scripting capability. Transport layer(Traffic Agent) – TCP, UDP, Interface queue – FIFO queue, Drop Tail queue, Priority queue, Design Simulation – Determine simulation scenario.
