Who invented the Internet Protocol?

Vinton Cert
In a research paper published in 1974, Vinton Cerf and Robert Kahn proposed a protocol they called "TCP". Cerf and Kahn didn't realize it at the time, but the protocol they invented would later become IP, the official network-layer protocol of the Internet.







Robert Kahn
In May, 1974, the Institute of Electrical and Electronic Engineers (IEEE) published a paper titled "A Protocol for Packet Network Interconnection." The paper's authors -- Vinton Cerf and Robert Kahn -- described a protocol called "TCP" that incorporated both connection-oriented and datagram services.
.It soon became apparent to the two men that this design should be subdivided into two separate protocols. Session management was not easy to do in an application-independent way. In practice, an application could sometimes run more efficiently or be implemented more easily when it managed network connections itself. "TCP" became Internet Protocol (IP) that supported datagrams and Transmission Control Protocol (TCP/IP) that added connection semantics as a layer on top of IP.
