TFGen is a free software that can be used to test the capacity of a network point to point using wireless or cable. It can generate traffic and measure the throughput, latency, jitter, and packet loss of the network. TFGen is useful for network administrators, engineers, and researchers who want to evaluate the performance of their network devices and links.
In this article, we will show you how to download and use TFGen for network testing. We will also provide some links to other resources that can help you learn more about TFGen and network testing.
How to Download TFGen
TFGen is available for Windows and Linux platforms. You can download it from the following sources:
SourceForge: This is the official website of TFGen, where you can find the latest version of the software, as well as documentation, screenshots, and reviews. You can also report bugs and request features here[^1^].
DatautamaNET: This is a website that provides various tools for networking, including TFGen. You can also find other useful programs such as BTest, PuTTY, and Winbox here[^2^].
Peatix: This is a website that hosts events and groups related to various topics, including networking. You can find a group that offers TFGen as a download here[^3^].
After downloading TFGen, you need to extract it and run the executable file (tfgen.exe for Windows or tfgen for Linux). You will see a graphical user interface (GUI) that allows you to configure and start the traffic generation and measurement.
How to Use TFGen
TFGen has two modes of operation: sender and receiver. You need to run TFGen on two machines that are connected by the network link that you want to test. One machine will act as the sender, which will generate traffic and send it to the receiver. The other machine will act as the receiver, which will receive the traffic and measure its characteristics.
To use TFGen, you need to follow these steps:
On the sender machine, run TFGen and select "Sender" from the Mode menu. You will see a window that allows you to specify the IP address and port number of the receiver machine, as well as the type, size, rate, duration, and interval of the traffic that you want to generate. You can also choose whether to enable TCP or UDP protocol for the traffic.
On the receiver machine, run TFGen and select "Receiver" from the Mode menu. You will see a window that allows you to specify the port number that you want to listen on, as well as the file name where you want to save the measurement results. You can also choose whether to enable TCP or UDP protocol for the traffic.
After configuring both machines, click "Start" on both windows. The sender will start sending traffic to the receiver, and the receiver will start measuring it. You will see a progress bar on both windows that shows how much time is left for the test.
When the test is finished, you can click "Stop" on both windows. The sender will stop sending traffic, and the receiver will stop measuring it. You can view the measurement results on the receiver window or open the file that you saved them in. The results will show you the throughput, latency, jitter, and packet loss of the network link during the test.
You can repeat these steps with different settings to test different scenarios and compare the results.
