Van Jacobson - People

Van Jacobson, the man widely credited with saving the Internet from an otherwise inevitable congestion collapse in the late 1980s, is chief scientist at networking startup Packet Design, LLC.

Jacobson began his career in data communications developing control systems for the Department of Energy in the 1970s. He is best known for redesigning the TCP/IP protocol's flow-control algorithms to better handle congestion, preventing the Internet's collapse from traffic congestion in 1988-89. He is also widely recognized for his work on network synchronization effects, scalable multimedia protocols and applications, IP operations tools (e.g., traceroute and pathchar) and high-performance TCP implementations.

Prior to joining Packet Design as a member of the founding team, Jacobson was chief scientist at Cisco Systems, and before that had been group leader for Lawrence Berkeley Laboratory's Network Research Group.
