Hi all. Is there any opensource packet generator which can simulate a load closest to real users? Usually I use iperf, but it can simply generate huge load.

Thanks, Snabb Switch's packetblaster seems to be what I am looking for. My goal using it is to find out how much of real users traffic my new softrouter can handle until it begin doing packet drops.

I would recommend Trex with pkgtgen-dpdk or netmap's pkgt-gen. Have your current router average packet size and rate and generate those patterns. If you just use the suggested tools the traffic pattern may be different from what you actually have. http://trex-tgn.cisco.com https://github.com/luigirizzo/netmap
