Worm generating network attack traffic?

Does anyone know any tools which can be used to generate network attack
traffic ? It is for the purpose of testing IDSs OR for collecting offline
intrusion detection dataset like 1999 DARPA dataset. I have windows xp
installed so i need a tool or worm tool to generate network traffic so that
i can collect by wireshark.
waiting ur reply.
