Editing Zephyr (protocol) (section)

==Creation==
Zephyr is the invention of Ciarán Anthony DellaFera who was, at that time, an employee of [[Digital Equipment Corporation]] and a Visiting Research Scientist at [[Project Athena]]. The design originated as a solution to the "reverse [[Remote Procedure Call]] (RPC)" problem: how can service providers (servers in a [[client–server]] system) locate and communicate with service users. The initial concept emerged from conversations between Ciarán and Michael R. Gretzinger, another systems engineer at [[Project Athena]], in early 1986. By mid to late 1986 Ciarán had distilled the problem to two specific issues: the ability to locate users in a [[distributed computing]] environment (known today as "presence detection"), and the ability to deliver scalable, light-weight, and authentic messages in a distributed computing environment. The Zephyr Development Team (Mark W. Eichin, Robert S. French, David C. Jedlinsky, John T. Kohl, William E. Sommerfeld) was responsible for the creation of the initial code-base and the subsequent releases that were issued throughout the late 1980s.
