Network Simulators Comparison

Network Simulators Comparison is also a technique of implementing the network on the computer.

Network simulator:

  • Through this the behavior of the network is also calculated either by network entities interconnection using mathematical formulas, or by capturing and also playing back observations from a production network

Comparison of network simulators:

The network simulators are of different types which can also compared on the basis of:

  • Range (from the very simple also to the very complex)
  • Specifying the nodes and links between those nodes and also traffic between the nodes
  • Specify everything about the protocols also used to handle traffic in a network
  • Graphical applications (allow users also to easily visualize the workings of their simulated environment.)
  • Text-based applications (permit more also advanced forms of customization)
  • Programming-oriented tools
