Stress Test Networks and Websites
Maximize uptime with synthetic network traffic generators. Perform network stress tests to verify quality of service (QoS), load test applications to prepare for demand spikes, and ensure a consistent user experience for staff and customers.

If There Is One Metric You Need to Deliver On, It's Uptime
Ninety-nine percent uptime and the gold standard of 99.9999% uptime are worlds apart. Over a calendar year, it is the difference between 87+ hours of downtime and 30 seconds. Users expect networks and applications to always be available. It is bad for business — and your reputation — if you let them down.
The key to finding and fixing the unpredicted and unexpected is chaos engineering. Read our playbook to discover the power of performance test, load test, and network stress test tools in chaos engineering — and how they can help you maximize uptime, reliability, and availability.
What Can You Do With Synthetic Traffic Generators?
Increase Realism with Application and Protocol Traffic Simulation
Traditional protocol-level client simulation is an effective and highly efficient way of putting a server under stress. But in terms of verification, it can only ensure that the client is receiving the correct messages from the server. It cannot verify that the user is getting the expected behavior or verify the user experience. Eggplant Performance interacts with the client machine exactly as a user does. By simulating network traffic loads and stressing client-side servers, you can validate application and network performance against real-world user interactions and behaviors.
Stress Test Websites and Applications at Peak Traffic Loads
IT departments must ensure that their website and back-end infrastructure can dynamically add capacity and scale to react to traffic surges. Eggplant Performance makes load testing simple and scalable — which is vital when network traffic stresses your servers and applications. Test any browser, application, or device with customizable parameters — including traffic volume, geographic location, and behavior profiles — and real-time client and server monitoring. Expand automation beyond load test execution to the full testing process, ensuring that your test scripts dynamically change in response to new releases, updates, changes in user behavior, or other factors that can affect user experience.
Validate Network Deployments Before Going Live
Organizations frequently add business services to their networks, and network equipment undergoes continual updates and upgrades. To avoid downtime and bottlenecks, you need network traffic generators to stress test the network, assess performance, and predict the quality of experience of newly deployed services. IxChariot simulates real-world application traffic to predict device, system, and network performance under realistic load conditions. It enables you to run network assessments and what-if scenarios across various transport interfaces, including wired, wireless, and virtual data centers.

Frequently Asked Questions About Synthetic Traffic Generation Tools
What is a network traffic generator?
Network traffic generators emulate real-world network and application traffic and inject it across websites and networks to stress test the network and measure performance metrics like load times, download rates, jitter, packet loss, and delay. These tools are essential for measuring network services, QoS, and user experience.
Typically, network traffic generators are used to test large-scale network deployments. Sometimes referred to as network assessment, common use cases include measuring service quality across distributed, hybrid networks and validating large-scale deployments like SD-WAN before going live.
What is performance testing?
Performance testing comprises a large subset of software quality assurance (QA) testing, including load testing, stress testing, volume testing, and scalability testing. Since these tests typically validate application clients, servers, networks and application devices against heavy traffic volumes, test automation is a prerequisite. These tests would be too time consuming to perform manually.
Performance testing tools simulate the actions of real users with efficient, low-overhead, and consistent virtual users (VUs). VUs enable QA test teams to quickly and repeatedly assess the performance of a system under test, resulting in shortened product cycles and improved user experience. Performance test suites often include powerful, easy-to-use tools that help testing teams create customized, dynamic VUs — enabling more complex and advanced testing where each VU has its own unique data and timings. Since users often take different paths across websites and applications, groups of VUs can run different scripts or workflows within the same test for greater real-world accuracy. By acting as an engine for coordinating the execution of dynamic and variable VUs, performance test tools simplify the process of deploying realistic tests against systems and environments under test.
What is load testing?
A specific subset of performance testing, load testing examines how applications, websites, and servers handle abnormally high traffic volumes. QA testers often run load tests before high-profile feature releases or high-traffic events like e-commerce sales or holidays to avoid website crashes and outages.
While load testing tools traditionally focus on generating application-layer traffic, Eggplant Performance is unique because it can also generate protocol-layer traffic. It acts as both a server and client, generating synthetic traffic loads to test websites and applications, network infrastructures, intermediate layers of N-tier architectures, and back-end equipment including routers and content-aware network devices.
