As a staff researcher and Internet technology pioneer at the MIT Laboratory for Computer Science, Chiappa invented the multi-protocol router. In addition to wide use at MIT, that router was later used at Stanford in 1982; other multi-protocol routers at Stanford were implemented independently by William Yeager. The MIT multi-protocol router became the basis of the multi-protocol router from Proteon, Inc., the first commercially-available multi-protocol router (January, 1986).
Chiappa also designed the original version of Trivial File Transfer Protocol (TFTP). He is acknowledged in several other RFC's, such as RFC-826, RFC-919, RFC-950 and others. He has worked extensively on the Locator/Identifier Separation Protocol (LISP).
He is currently working on long-term issues in both the Internet Research Task Force and Internet Engineering Task Force and its predecessors; he served as the Area Director for Internet Services of the Internet Engineering Steering Group from 1987-1992. Chiappa is listed on the "Birth of the Internet" plaque at the entrance to the Gates Computer Science Building, Stanford.
Among many non-technical interests, he is particularly interested in Japanese woodblock prints, and helps maintain online catalogue raisonnés for two major woodblock artists, Tsukioka Yoshitoshi and Utagawa Hiroshige II.
Chiappa lives in Yorktown, Virginia with his family.
