JPacketGenerator

JPacketGenerator is a simple application developed in Java, which gives you the possibility to generate UDP traffic in order to control the network status. It enables you to specify the stream speed and size of sent packets.

No setup necessary, besides Java

The entire program's packed in a single executable .jar file that can be saved anywhere on the disk or copied to a removable storage unit, in order to seamlessly launch it on any PC with as little effort as possible, as long as it has Java Runtime Environment installed.It doesn't add new entries to the system registry or create files on the disk without your permission. In order to uninstall it, you simply have to delete this file.

Clear-cut interface and options

The GUI is user-friendly, represented by just one window that reveals all options provided by this tool. The source address can be selected from a drop-down menu.In the following step, you can specify the destination IP address and port number, along with the packet size (bytes) and stream speed (kilobytes per second).The packets can be sent at the specified speed with the click of a button. This action can only be halted by the users ("Stop" button), since there is no option implemented for automatically stopping it after a particular interval time has passed. No window pops up after starting or stopping the UDP traffic, though.

Evaluation and conclusion

The software application didn't put a strain on the computer's performance in our tests, since it needed a low amount of CPU and RAM to work properly. No error dialogs popped up and it didn't hang or crash.On the other hand, it doesn't come equipped with richer options for experienced users looking for more control over UDP traffic. Nevertheless, Port Forwarding Wizard for Mac gets the job done and can be easily used by those who want to test their network by transferring packets.
