During the 1960s, the Defense Advanced Research Project Agency funded a research to allow the continuous flow of communication between the Department of Defense (DoD) community called the ARPANET, which is popularly known today as the Internet. The Internet Protocol Suite of the TCP/IP was the result of the project which is a key component in the development and growth of the internet and it was designed by [[Vinton Cerf]] and [[Robert Kahn]] in 1974 as described by RFC 675, Specification of Internet Protocol Programs.<ref>[http://tools.ietf.org/html/rfc675 RFC 675]</ref> In 1983, TCP/IP became the standard of communication wherein all hosts networks connected to the ARPANET were instructed to convert to the new protocols.<ref>[http://student.ing-steen.se/IPv4/TCP-IP.pdf History of TCP/IP]</ref>
