OcNOS CP by IP Infusion: A Brief History of ZebOS

ZebOS was created in 1999 by IP Infusion to commercialize a version of Zebra OS, a routing software package which offered platform independent protocols such as BGP, OSPF and RIP. Zebra OS was the world’s first routing engine software, created by Kunihiro Ishiguro and Yoshinari Yoshikawa in 1996 and distributed under an open source license. ZebOS was created to provide a commercially supported and enhanced alternative to the open source Zebra OS, catering to the needs of network equipment manufacturers and customers requiring professional support and features.

Upon launch, the ZebOS product found immediate success, becoming the platform of choice for many of networking’s most innovative companies including Fortinet, Citrix, A10 Networks, F5 and many others.

IP Infusion continued to develop and refine ZebOS, turning it into a comprehensive and commercially supported network operating system. It provided additional features, support, and services compared to the open-source Zebra, making it a compelling choice for network equipment manufacturers.


ZebOS was recently rebranded as OcNOS CP, to more accurately reflect the product brand in the context of the IP Infusion product portfolio.

IP Infusion’s OcNOS CP (Control Plane) is an integral part of the OcNOS (Open Compute Network Operating System) product family. It is a highly scalable and feature-rich control plane solution designed to provide advanced networking capabilities for data centers, service provider networks, and enterprise environments.
