Glenn Ricart
Encyclopedia
Dr. Glenn Ricart is a computer scientist. He started using one of the original Internet (ARPANET
) nodes in 1969.
He set up what was probably the first Internet Exchange point, the FIX (Federal Internet Exchange) in College Park, Maryland
which interconnected the original federal TCP/IP networks and was extended to form MAE-East
.
Dr. Ricart led the team that wrote the code for the first implementation of TCP/IP for the IBM PC. He then secured financial support from IBM
for writing the code, and, in addition to its free availability to the education community, arranged for IBM to sell it as IBM's entry into the field (the product was called PC/IP by IBM).
He led the team that developed the OSPF reference implementation at the University of Maryland, including Louis Mamakos and Mike Petry.
He also led the team that provided and operated the routers for the first NSFNet
backbone.
The Ricart-Agrawala Algorithm
was the result of his dissertation work at the University of Maryland
.
From 1971-1982, he was a lead software engineer at the National Institutes of Health
, developing the first e-mail program for the TOPS-10
(PDP-10
) operating system in 1973. From 1982-1993, he headed academic computing at the University of Maryland
. In 1984, it became the first campus to adopt TCP/IP campus-wide and use it to connect all academic minicomputers and mainframes.
In 1985-1989, he was instrumental in bringing the Internet
to South America
, helping to bring the first BITNET
and Internet connections to Brazil
in partnership with CNPq, Argentina
via the University of Buenos Aires
, and Chile
by first connecting REUNA. He instructed the first networking workshop for Latin and South America (ESLARED) and several succeeding workshops.
From 1993 to 1995, Ricart was a Program Manager at DARPA for operating systems, middleware
, and end-system security. From 1995-1999, he was Chief Technology Officer at Novell
, helping to move that company from the proprietary XNS protocol to also embrace TCP/IP. In 1999, he co-founded CenterBeam, a start-up based on remote system management driven by directory services.
From 2003-2009, he was the founding Managing Director of the PricewaterhouseCoopers
Center for Advanced Research based in San Jose, California
.
In October 2009 Ricart was named president and CEO of National LambdaRail
, the high-speed networking platform owned by the U.S. research and education community. On September 7, 2010 Glenn Ricart announced his resignation from National LambdaRail due to strategic differences with the Board. The NLR Board thanked him for his leadership and wished him well.
He currently serves on the board of the Public Interest Registry
. He previously served on the boards of the Internet Society
, BITNET
, CACI
, First USA Financial Services, Santa Cruz Operation, and NASULGC.
Dr. Ricart received his B.S. degree in Engineering from Case Institute of Technology in 1971, and his M.S. in Computing and Information Sciences from Case Western Reserve University
in 1973. He received his doctorate in Computer Science from the University of Maryland
in 1980.
