Bob Metcalfe was named the winner of the 2022
A.M.Turing Award.Fifty years ago,Metcalfehelped invent (/),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 (作答此空)adjust average wait timesbetween transmission attempts,taking the
frequency of (/)into account:They'd be quickerto try again if the frequency was low,and they'd
(/)if the network was crowded,making
communication much more efficient overall.
