NetStress-NG is a network stress testing tool that allows users to simulate network traffic and measure the performance and stability of their network infrastructure. It is an upgraded version of the original NetStress tool, with added features and improvements.
NetStress-NG can generate various types of network traffic, including TCP, UDP, and ICMP packets, and allows users to customize traffic parameters such as packet size, bandwidth, and latency. This enables users to simulate real network conditions and test the capacity and resilience of their network.
The tool provides detailed statistics and charts for analyzing network performance, including throughput, latency, and packet loss. It also offers advanced features such as multi-threading, allowing users to generate a large amount of traffic and stress test their network.
NetStress-NG is a versatile tool that can be used for network benchmarking, troubleshooting, and capacity planning, among other purposes. It is commonly used by network administrators, IT professionals, and network equipment manufacturers to evaluate the performance and reliability of their network infrastructure.
In summary, NetStress-NG is a powerful network stress testing tool that provides users with the ability to simulate and measure network traffic, helping them identify and resolve any performance or stability issues in their network.
