Multicast traffic generator for Windows

Are there any multicast traffic generators for Windows?

Multicast traffic is actually pretty simple to create with any programming language. If you got python installed here's an example, I hope it works under Windows.

import sys
import socket
from time import sleep
UDP_IP=sys.argv[1]
UDP_PORT=sys.argv[2]
TTL=2
DATA="whateverandever"
sock = socket.socket( socket.AF_INET, socket.SOCK_DGRAM )
sock.setsockopt(socket.IPPROTO_IP, socket.IP_MULTICAST_TTL, TTL)
while True: sock.sendto ( DATA, (UDP_IP, int(UDP_PORT)) ) sleep(1)

Save it to i.e. mcast.py and execute it like this:

python mcast.py <destination> <port>

Change TTL in the script if you whant the traffic to reach further down in the network.
