A.M.Turing Award.Fifty years ago,Metcalfehelped invent (作答此空),the localnetworking technology that links personal
computers around the world to the global internet.The fundamental problem of computer networkingwas how to share access to a network amongmany users.In the early 1960s computer scientistLeonard Kleinrock showed that (/)theory couldalso describe the flow of data through a network.Any user whose message was lost or garbledbecause of a conflict would simply try again aftera random time interval.In Metcalfe's improvedmodel,users would (/)adjust average wait timesbetween transmission attempts,taking the
