NETWORK TESTING AND SIMULATION TOOLS
Network IP traffic packet generators are used for network performance testing under maximum or partial throughput conditions. Network health can be analyzed by network traffic measurement in a testbed network, using an IP network traffic generator such as IP Traffic Test and Measure. The traffic generator sends packets, often with a unique packet identifier, making it possible to keep track of the packet delivery in the network.
Network impairment simulation (emulation) is a technique for testing the performance of real applications over a virtual network. The aim is to assess performance, predict the impact of change, analyze impairment conditions or otherwise optimize technology decision-making. Measurements usually focus on simulation of conditions like delay, jitter, latency, dropped packets and limited bandwidth.
