http://www.wireshark.org/ What do the creator of TCPDUMP, the creator of Wireshark, and the creator of WinPcap have in common? In addition to pioneering packet capture and analysis, they also happen to work for Riverbed.

Riverbed co-founder and CTO Dr. Steve McCanne worked with TCP/IP pioneer Van Jacobson in 1988 during the days of Arpanet. Van was working on the TCP/IP stack and needed a reliable way to capture and efficiently analyze enormous amounts of network traffic. Steve came up with an innovative solution that took an elegant, filter approach to capturing only the traffic you need. Steve's packet capture invention was released into open source as the Libpcap library and ultimately as the application TCPDUMP.

Several years later in the late 90's, Loris Degioganni was a student at Politecnico di Torino, Italy. Loris was tasked to come up with a way to capture network traffic from student's windows machines. Loris came across a paper co-authored by Steve McCanne and he leveraged Steve's work, taking Libpcap and building a windows capture library, which he released into open source under the name WinPCap.

Around the same time, a network guy by the name of Gerald Combs was working for an ISP and needed a more robust way of analyzing packet captures. Gerald started a weekend project that exploded to much more and Ethereal/Wireshark was born.

This video was taken during Riverbed's 2011 sales kick-off in Denver, CO.
