[3] As her name appears first in the original paper, she seems to have been the one who was behind the simulation programmed in Fortran, showing that packet switching (or "hot-potato routing" as it was called) could indeed work.
[1] In an earlier paper from May 1960,[4] where only Paul Baran is credited as an author, he directly credits "Miss Sharla Perrine" as the person who wrote a program to perform a Monte Carlo Simulation, further lending credibility to her also writing the code in the 1964 paper.
In RAND and the Information Evolution, Baran describes how Boehm carried out various simulations under different conditions, demonstrating that the protocol routed traffic efficiently.
[5] In a 1996 paper on "An Early Application Generator and Other Recollections", Barry Boehm notes that Sharla Boehm "had developed the original packet-switched network simulation with Paul Baran", a development which led him to become involved in the pioneering ARPAnet Working Group.
[6] It seems likely he is referring to the May-1960 paper "Reliable Digital Communications Systems Using Unreliable Network Repeater Nodes" described and referenced above.
