WAN / Network Simulation

Network Simulation and Network Emulation - The Differences

Network Simulation is often confused with Network Emulation but they are not the same and have very different purposes.  Network Simulation is used to model the behaviour of a network by calculating the interaction between the different network entities using mathematical formulas.  You cannot run real network traffic through a Network Simulator but you can through a Network Emulator.  
Network Emulators are used by organizations that need to verify application performance in an environment that accurately replicates the real-world networks whereas Network Simulators are generally used for academic or research purposes.

iTrinegy offers a comprehensive range of WAN Emulation products to enable you to realistically recreate the conditions of your existing (or proposed) IT network in a safe off-line environment.

It is then possible to test the performance of new (or existing) applications in this replicated network, safe in the knowledge that you are not going to bring down your organization’s live production network which will be hosting mission-critical applications and services.

Furthermore, using one of iTrinegy's network emulators will enable you to make changes to, and model a network environment in ways that your network manager would simply not allow in the live network or enable you to model how the application will work over new networks that you do not have ready access to.

iTrinegy Network Emulator products can be used to emulate a variety of networks including:

  • High Latency WANs (National, International, Satellite) Wireless Networks (e.g. Wi-Fi, WiMAX and 3G)
  • Jittery networks - such as cause VoIP deployments a problem
  • Networks that lose and/or damage traffic
  • QoS based networks (e.g. MPLS)
  • Routed Networks

and all combinations of these types of network.

Typical network impairments that the iTrinegy Network Emulators can produce for each network segment include:

  • Bandwidth Restrictions
  • Delay (Latency and Jitter)
  • Packet Re-ordering, Packet Error and Packet Loss
  • Traffic Shaping and Traffic Prioritization (QoS) - INE Enterprise and INE Ultra only
