Because Vint Cerf laid the foundation of contemporary Internet, contain the male relative of a senior generation that develop TCP/IP network agreement jointly and is considered as contemporary Internet. In article, vint Cerf told about the process that develops TCP/IP agreement in those days. All everything of Internet is in by Vint Cerf and his development group now at American national defence advanced research planned arrange 1969 (U.S. Defense Advanced Research Projects Agency, DARPA) next ARPANET experiments begin, vint Cerf and his group is considering to seal packet of latent capacity that exchanges communication in the experiment at that time. Networks of a variety of the exchange that seal a bag are developed by ARPANET at that time, act for example the radio that seal a bag and the satellite that seal a bag, do not cross the language that there is applicable to both or all between each other, every network uses his communication agreement to exchange a bag, because this is over between each other,devoid law delivers message. To solve this problem, vint Cerf and his colleague Robert Kahn developed TCP of agreement of newsletter of a computer (Transmission Control Protocol) , support the message between network of the different exchange that seal a bag to deliver. Occupy to support solid duration further later, include audio to transmit, they divide TCP into two parts again, among them a part is incognito for IP (Internet Protocol) , the TCP/IP agreement with contemporary then commonly used network is formal figuration. Zun Qi Vint Cerf, robert Kahn, jon Postel. TCP/IP agreement is in later 3 kinds of networks below DARPA check, make new standard eventually. 1981 Jon Postel compose transfer the 400 servers all below plan general ARPANET to be changed into TCP/IP agreement from old NCP agreement, appoint deadline to be on January 1, 1983, the server that has not transferred after this deadline will break a string. In final deadline that day, vint Cerf is the mainest the mood that experiences is to loosen, do not have any celebration, also cannot find any pictures, the person that the evidence that leaves exclusively is course changeover deserves haughtily to carry “ I Survived The TCP/IP Switchove “ pectoral chapter. Look from now, that day is a commemorable circumstance really, internet is born formally, TCP/IP makes international standard later, propping up whole Internet now. The TCP/IP that is apart from Vint Cerf and Robert Kahn now studies the paper already had 40 years, although in those days they are having very tall expectation, did not think of Internet can grow nevertheless for present cosmopolitan platform. Vint Cerf thinks he is honoured very much can amid acts a part, and proud like any parents is same, look at it gladly to grow, continue all future that protect it possibly, let we and Vint Cerf celebrate 30 years old of birthday of Internet together!
