Thank you, Chair, and thank you, Mr. Rohozinski, for being here.
You talked about a variety of things. It's interesting to note that there are so many issues relating to cyber-attacks, etc. But going down to the most fundamental aspects of it, Internet protocols, can you just explain to this committee who writes them, how do they get implemented, etc? Those are the fundamental elements of communications across the cyber-network, which I don't think anybody really considered seriously when they were talking about the wider use of the Internet as we see it now. As you know, it came from a protocol between universities way back when, so can you just help us understand the fundamental aspect of that? Could you also address the hardware side, if you get a chance to do that?
