</ref> Co-developed the monitor with Tony Hoare, and created the first monitor implementation.<ref>

</ref> Implemented the first form of remote procedure call in the RC 4000,<ref name=“:0” /> and was first to propose remote procedure calls as a structuring concept for distributed computing.<ref>

</ref> Many of the wide-area packet-switched networks built in the 1970s, including the ARPANET, were similar “in nearly all respects” to his original 1965 design.<ref name=“:2”>

</ref> His scanned photo of his three-month-old son was deemed by ''Life'' magazine as one of the “100 Photographs That Changed The World.”

</ref> He later published several of the standard works on the subject. In the early 1970s, he applied this theory to model the performance of packet switching networks. Kleinrock played an influential role in the development of the ARPANET, the precursor to the Internet. His theoretical work on hierarchical routing in the late 1970s with student Farouk Kamoun remains critical to the operation of the Internet today.
