WAN Killer: The Network Administrator's Guide to Stress Testing

The SolarWinds® WAN Killer Network Traffic Generator is a specialized utility designed to stress test wide area network (WAN) links by generating a controlled flood of random traffic. It is a critical component for network administrators who need to validate bandwidth capacity, test Quality of Service (QoS) configurations, and predict how infrastructure will behave under sudden spikes in load. What is WAN Killer?

Unlike standard traffic simulators that mimic specific user activities, WAN Killer acts as a "bandwidth blaster." It allows you to target a specific IP address or hostname and send a continuous stream of UDP or TCP packets to test the connection's breaking point. Key Features and Customization

The tool provides granular control over the generated traffic to ensure tests are as realistic as possible:

Packet Size Control: Use a slider to adjust the size of the packets. Smaller packets result in a higher number of packets per second, which more effectively stresses the CPU of network devices. wan killer 1.1 download

Bandwidth Percentage: Specify exactly what percentage of the circuit's total bandwidth should be consumed by the test traffic.

Protocol Support: While primarily used for random UDP traffic, it can also utilize TCP or UDP echo protocols to route symmetrical traffic, provided the target device is configured to respond.

DSCP and ECN Modification: Advanced users can modify Differentiated Services Code Point (DSCP) and Explicit Congestion Notification (ECN) settings to test how the network prioritizes specific traffic types. How to Get WAN Killer

WAN Killer is not available as a standalone 1.1 download but is exclusively part of the SolarWinds Engineer's Toolset™ (ETS).

SolarWinds Engineer's Toolset (ETS): This comprehensive suite includes over 60 essential tools for network troubleshooting, diagnostics, and monitoring.

Trial Access: You can download a fully functional free trial (typically 14 to 30 days) of the Engineer's Toolset from the official SolarWinds website.

Installation: Once installed, you can find the WAN Killer tool located under the Diagnostics folder in the Toolset dashboard. Best Practices for Stress Testing

Because WAN Killer is designed to saturate links, it should be used with caution:

Test Off-Hours: To avoid disrupting actual business operations, always schedule stress tests during maintenance windows or off-peak hours.

Monitor the Target: WAN Killer only generates traffic. Use other tools like SolarWinds Network Performance Monitor or packet sniffers like Wireshark to analyze the results and see at what point the target begins dropping packets.

Check Local Limitations: The maximum traffic generated is limited by the bandwidth of the network card in the machine where WAN Killer is installed. Top Alternatives for Traffic Generation

If you require different features or open-source options, consider these alternatives:

Ostinato: A GUI-based open-source packet generator for Windows, macOS, and Linux that allows for complex custom packet crafting.

Cisco TRex: A high-performance, open-source traffic generator capable of reaching up to 200Gb per second.

Nping: A powerful command-line tool from the creators of Nmap, used for packet generation and response analysis.
