can you suggest a traffic generator software?

hi mates :)

Need some help:

I need a software (preferably freeware/shareware) that generates traffic (tcp or udp).

In order to test the bandwith, we want to control the speed of the transmitted packets. so the generator should be able to generate traffic on different scales (20 Mbps,30 Mbps etc)

Is there such a software? I will very much appreciate if you can suggest me what I need.

Thanks for helping :)

Re: can you suggest a traffic generator software?

The US Navy developed software called "RAPR" that might do what you want. Here is the link:

From their website:

"The goal of RAPR is to develop a tool that generates real-time traffic patterns in a manner closely tied to application behavior so that the network can be loaded in a variety of ways. The generated traffic will be received and logged for analyses. Script files will be used to drive the behaviors and resulting generated loading patterns over the course of time. These script files will be able to emulate the traffic patterns of unicast and/or multicast UDP/TCP/IP applications. The receive portion of this tool set will be able to be scripted to dynamically join and leave IP multicast groups. RAPR log data will be able to be used to calculate performance statistics on throughput, packet loss rates, communication delay, and more. "

Also, there are other tools like:

And probably a more well known one is:

Good Luck!
