Traffic generator for IPv4 and IPv6

Hi all,

I need a network traffic generator that is capable of generating loads of different types of traffic over IPv4 and IPv6 networks. The devices involved are Windows-based PCs, along with Cisco routers and switches.

My only prerequisite is that it is has a GUI to more clearly show my results. An app that would also give me load/time statistics would be ideal as well, but I don't mind sourcing another program for that.

Thanks in advance.

To be honest, I don't know of a specific one. But check the following list, see if any fill your needs:
