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
