Today we are in a position where, if nothing is done, we are going to have a meltdown in two years or so. Because the TCP, which is the protocol we are using for flow control, is an Internet protocol that is sitting there banging back and forth trying to control the rate at which each person sends so that they don't exceed the network. As the volume on the network grows, the speeds of everything have to go up, so we are raising the speed of the entire network and the trunks and the access lines that everybody is working from. The result is that you are losing more and more data in the oscillation peaks. And every time you lose it you have to retransmit it, and it gets worse and worse.
Efficiency goes down, overall, as the speed of the network goes up.
TCP just has to change. Unfortunately, that is a bad scenario because if you lose a little bit more everybody retransmits more and the volume goes up rather than remaining stable. So it gets worse and worse as things get worse. That is a problem which we have got to change, in the way I've talked about, by getting flow control in the network, real flow control at the electronic level. The problem with real-time audio or voice or video or anything like that is, once you lose it you can't retransmit it.
