It's not a protocol.

Again, it's not a protocol. It's an FEC algorithm. No current mainstream 
protocol specifies using it. It will take decades, at least, and it 
definitely cannot fit into existing protocols.

Custom closed-source video transmission protocols are using it.
But, I do believe it's the future for open-source protocols too.
