History of Quagga / Zebra• 1996 : Zebra Project (Open Source Software)
• Kunihiro Ishiguro realized the need for quality routing software.
• He started “Zebra Project” and created the world's first OSS routing engine software.
• 1999 : ZebOS, Commercial version of Zebra.• “IP Infusion” was founded to provide commercial
version of Zebra, ZebOS.
• Co-Founders: Kunihiro Ishiguro, Yoshinari Yoshikawa.
• ZebOS is being used in various commercial network equipment.
• 2005 : Quagga forked from Zebra Project.• Zebra Project was discontinued from various reasons.

• 2011 : OSR was formed to host Quagga (*1)• OpenSourceRouting (OSR) started in 2011 by an
initiative of the Internet Systems Consortium (ISC, www.isc.org) and Google.
• Objective was to help develop a robust and tested alternative network stack and re-ignite the open source community behind Quagga.
• 2014 : NetDEF Takes Ownership of OSR (*2)• In early 2014, ISC transferred the OpenSourceRouting
project to the Network Device Education Foundation (NetDEF, www.netdef.org), a non-profit corporation based in the Silicon Valley.
