Data center networking with OpenSwitch

Switched On

What Remains at the End

OpenSwitch is currently available in version 0.4. Much has happened since its release just over a year ago – and not just in the technical details. In particular, OpenSwitch, being under the auspices of the Linux Foundation, ensures sustainability and further development. HPE is a renowned manufacturer of switch hardware backing the project.

OpenSwitch is not the only player in the NOS market. Dell, for example, cooperates with Cumulus Networks and has a development of its own on the roadmap: OS 9 (Dell NOS 9) [29] based on NetBSD. Another is VyOS [30], which has a history in the Brocade camp.

The project documentation is quite extensive, with just a few open construction sites. Some examples are even misleading, because they fail to mention much-needed parameters. Elsewhere are references to outdated versions.

At the end of the day, OpenSwitch is a complete open source operating system for switches based on well-known projects such as Yocto or ONIE that offers Linux users easy entry to data center networking.
