Fast and Accurate Simulation of Scalable Networks
白皮书
Network planners use simulation to assess the performance of networking technologies and applications under a diverse set of operational conditions. A large amount of number crunching is required to answer questions such as “How will the latency of my video conferencing application be affected if I add 50 new users to the network?” or “How will the data link be able to support the mission requirements if an airborne asset is lost”? or “How long will it take the network administrator to detect a DDOS attack and restore network operations?” or “What are the likely operational impacts of cyber threats, such as virus and worm propagation, route poisoning, and DDOS and jamming attacks, on mission completion?”
Network simulation offers an efficient, cost-effective way to assess how the network will behave under different operating conditions and answer questions like the ones above. Simulation results can be analyzed to assess network performance, identify potential problems, understand the root cause, and resolve issues prior to deployment. Since running simulations in the laboratory is much faster and much less expensive than performing live tests, it is much easier to investigate different alternatives using simulations before deploying a network or making changes to an existing network.
