Today is the 30th birthday of the modern-day Internet. Five years ago we marked the occasion with a doodle . This year we invited Vint Cerf to tell the story. Vint is widely regarded as one of the fathers of the Internet for his contributions to shaping the Internet’s architecture, including co-designing the TCP/IP protocol. Today he works with Google to promote and protect the Internet. -Ed. packet switching communication was operationally tested in the grand ARPANET experiment by the U.S. Defense Advanced Research Projects Agency (DARPA). communications protocol using different conventions and formatting standards to send and receive packets, so there was no way to transmit anything between networks. A Protocol for Packet Network Intercommunication .” Later, to better handle the transmission of real-time data, including voice, we split TCP into two parts, one of which we called “Internet Protocol,” or IP for short. The two protocols combined were nicknamed TCP/IP. a transition plan to migrate the 400 hosts of the ARPANET from the older NCP protocol to TCP/IP, including a deadline of January 1, 1983, after which point all hosts not switched would be cut off.
