This is a utility to generate UDP Multicast packets at speeds up to 210Mbps (has been tested to reach 995Mbps).
It has a client and server utility. The server starts generating UDP multicast packets (64k in size) and the 
Listener utility will recieve them and verify them, keeping track of number of errors detected.

USAGE:  -a [multicast group], -p [port]
        -t [runtime duration (10s default)]
        -e [number of errors to inject into each packet (default 0)]
        -s [speed to run at in Mbps (default 160)]
        -S [speed to run at in MBps (default 20)]
        -T [Number of THREADS to run (default 1)]
        (e.g. for SSDP, `sender -a239.255.255.250 -p7777 -s100 -t10`)
