There are two main data transfer protocols — Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). If you only had to know one fact about each protocol, it’s that TCP is slower because it takes time to check for errors, and UDP is faster because it doesn’t check for errors as much. Obviously, as shown by both protocols, having to vigorously check for errors limits the speed of a transfer protocol, but Fujitsu has announced that it has found a way to add error-checking into a UDP-like protocol and keep the higher speed.
