Packet Sender

Nping is an open source tool for network packet generation, response analysis and response time measurement. Nping can generate network packets for a wide range of protocols, allowing users full control over protocol headers. While Nping can be used as a simple ping utility to detect active hosts, it can also be used as a raw packet generator for network stack stress testing, ARP poisoning, Denial of Service attacks, route tracing, etc. Nping's novel echo mode lets users see how packets change in transit between the source and destination hosts. That's a great way to understand firewall rules, detect packet corruption, and more.

It’s often not enough to focus on latency or bandwidth utilization. Network stress testing can reveal how spikes in packet levels may impact network device performance. The WAN Killer tool in Engineer’s Toolset serves as a network stress tester by generating and sending packets to provide a realistic idea of how devices would perform in the event of sudden or extreme jumps in traffic. The information you get from a network stress test can help you figure out how to strengthen your infrastructure before serious issues occur. Being able to simulate network traffic means you can take a proactive approach to managing network performance, which is useful if, for instance, you plan to roll out a new application to your network. You can also send simulated traffic to see if your application’s traffic will receive appropriate priority. If not, you can find and resolve the issues that may stand in the way of providing the best quality of service.
