NetSim Lab

NetSim :- A network simulator enables users to virtually create a network along with its components such as devices, links, and applications etc. to study the behavior and performance of the Network.

Some examples of applications of network simulators are

 Protocol performance analysis

 Application modeling and analysis

 Network design and planning

 Research and development of new networking technologies

 Test and verification

The key features essential to any network simulation are -

 Building the model – Create a network scenario with devices, links, applications etc

 Running the simulation - Run the discrete event simulation (DES) and log different performance metrics

 Visualizing the simulation- Use a packet animator to view the flow of packets

 Analyzing the results - Examine output performance metrics such as throughput, delay, loss etc. at multiple levels - network, sub network, link, queue, application etc.

 Developing your own protocol / algorithm - Extend existing algorithms by modifying the simulators source C code
