What are Network Traffic Generators for Windows?

Network traffic generators, also known as traffic generators or website traffic generators, are tools used to simulate the behavior of network traffic. They are used by network administrators to test the performance, features, and scalability of their networks. Network traffic generators can generate a variety of types of network data including ICMP, UDP, TCP and application layer protocols such as HTTP and FTP. This helps ensure that the network is able to handle normal levels of traffic as well as peak loads. Additionally, they can be used for security testing purposes along with identifying weaknesses or misconfigured elements in a communication system.

    WAN Killer

    WAN Killer

    SolarWinds

    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.
