Van Jacobson is an American computer scientist, renowned for his work on TCP/IP network performance and scaling.[1] He is one of the primary contributors to the TCP/IP protocol stack—the technological foundation of today’s Internet.[2] Since 2013, Jacobson is an adjunct professor at the University of California, Los Angeles (UCLA) working on Named Data Networking.
Early life and education
[edit]Jacobson studied Modern Poetry, Physics, and Mathematics and received an M.S. in physics and a B.S. in mathematics from the University of Arizona.[3] He did graduate work at Lawrence Berkeley Laboratory.[4]
Career
[edit]His work redesigning TCP/IP's congestion control algorithms (Jacobson's algorithm)[5][6] to better handle congestion is said to have saved the Internet from collapsing in the late 1980s and early 1990s.[7] He is also known for the TCP/IP Header Compression protocol described in RFC 1144: Compressing TCP/IP Headers for Low-Speed Serial Links,[8] popularly known as Van Jacobson TCP/IP Header Compression.
He is the co-author of several widely used network diagnostic tools, including traceroute, tcpdump, and pathchar. He was a leader in the development of the multicast backbone (MBone)[9] and the multimedia tools vic,[10] vat,[11] and wb.[12]
Jacobson worked at the Lawrence Berkeley Laboratory from 1974 to 1998 as a Research scientist in the Real-time Controls Group and later group leader for the Network Research Group.[13] He was Chief Scientist at Cisco Systems from 1998 to 2000.[14] In 2000 he became Chief Scientist for Packet Design, Inc. and in 2002 for a spin-off, Precision I/O.[15] He joined PARC as a research fellow in August 2006.
In January 2006 at Linux.conf.au, Jacobson presented another idea about network performance improvement, which has since been referred to as network channels.[16] Jacobson discussed his ideas on Named data networking (NDN), the focus of his work at PARC, in August 2006 as part of the Google Tech Talks.[17][18] Van Jacobson is now working with the NDN Consortium funded by the National Science Foundation to explore and create the future of the internet.
Awards and memberships
[edit]Van Jacobson together with his colleague at LBL, Steven McCanne, won R&D Magazine's 1995 R&D 100 Award for development of a software toolpack that enables multiparty audio and visual conferencing via the MBone (Multicast Backbone).[19]
For his work, Jacobson received the 2001 ACM SIGCOMM Award for Lifetime Achievement "for contributions to protocol architecture and congestion control",[1] the 2002 IEEE Koji Kobayashi Computers and Communications Award,[7] and was elected to the National Academy of Engineering in 2004 for his "contributions to network protocols, including multicasting and the control of congestion."[20]
In 2012, Jacobson was inducted into the Internet Hall of Fame by the Internet Society.[21]
