Leonard Kleinrock

Pioneer of queueing theory for computer networking.

Last updated

He received a Ph.D. from MIT in 1963 and currently serves as a Distinguished Professor of Computer Science at UCLA.[1] Kleinrock is a member of the National Academy of Engineering and has published over 250 papers and six books.[1]

Life and work

Kleinrock received a Bachelor of Electrical Engineering degree in 1957 from the City College of New York.[2] He joined the faculty at UCLA, where he served as chairman of the Computer Science Department from 1991 to 1995.[2] In 1968, Kleinrock was awarded a contract to establish a Network Measurement Center (NMC) for the ARPANET.[3] The first message on the ARPANET was sent from UCLA on October 29, 1969, under Kleinrock's supervision.[4]

The literal first message transmitted was "lo" because the system crashed after the first two letters.[5]

What the cited sources add

The Internet Hall of Fame notes that Kleinrock has published over 250 papers and authored six books on topics including packet switching networks and broadband networks.[1] The Living Internet account states that Kleinrock published his first paper on digital network communications in July 1961.[6] According to the Living Internet, Roberts used Kleinrock's book "Communication Nets" to help convince colleagues that a wide area digital network was possible.[6] The Living Internet reports that Kleinrock's NMC connected an SDS Sigma 7 computer to an Interface Message Processor in early September 1969, becoming the first node on the ARPANET.[6]

The Living Internet states that Kleinrock led a CSTB committee in 1988 that laid the framework for today's Gigabit Internet networks.[6]
