The OSC protocol can be used to communicate between vvvv and other software like Ableton Live, Pure Data, Max/MSP, Resolume... you name it.
OSC is useful when you want to send different parameters via one udp-port. OSC adds an "address" to your data that you can conveniently filter for on the receiving end.
Examples in your vvvv\girlpower\ directory:
- IO\Networking\2_Advanced (OSC)
