New network modeling software tools are proving that faster simulation speeds and greater scalability are achievable through smart architecture and optimized memory management. This paper discusses the critical factors that determine the speed of simulation, which is often the deciding factor in choosing a tool, and show that speed and scalability are directly linked. Scalability means the simulator can support large volumes of traffic, complex node mobility and hundreds or thousands of devices and connections.
This paper discusses how software developers build scalability into simulators. Finally, it give examples of the level of speed and scalability achievable with QualNet, a network simulator designed from the outset for maximum speed and scalability, with real-time simulation as an achievable goal.
