I have just been reading about new techniques to speed up and improve the security of TCP/IP, and I am a little confused. Multipath TCP, which has already been implemented in some devices, is supposed to allow different packets in a transmission take different paths on the way to the receiver. Network coding is supposed to allow transmissions to be received in any order. Together, these could speed up internet transmission by a factor of 10.
My confusion is this: Wasn't TCP/IP designed to do this already? I thought that was the whole point of the protocol, that the transmission didn't have to take a single path and the individual packets didn't have to arrive in order. Is it that TCP/IP was never intended to work that way, or just that it doesn't actually work that way in practice?
