VoIP evolved from NVP, which was funded by ARPA but developed Information Sciences Institute of University of Southern California. NVP was designed to scale all the way down to conventional telephone networks, meaning it had to work at what we now call dial-up speed. If you think about it, this makes perfect sense: if you can use the conventional telephone network (which must be limited to a maximum speed of 56kb), then why can't you packetize the data and do the same?
VoIP "needs" broadband because it's a marketing point. Mainly it's because it's grown to be extremely inefficient and because the internet is poorly designed and overloaded, and now subject to turbulent weather (you know, those days where everything is slow, high packet loss, service loss).
Like most IT-problems, too much available resource has made people lazy when it comes to protocol specifications and programming. |
