Microsoft SONiC and Barefoot Networks At The OCP Summit

From an article at The Register regarding Microsoft’s SONiC network operating systems: Microsoft coordinated a bunch of announcements at the Open Compute Project summit this week, centred around its SONiC open switch software platform. SONiC, as you may recall, is Microsoft’s Debian based network operating system which it has donated to the Open Compute Project. Worth noting SONiC has now attracted Barefoot Networks: Barefoot’s another fan, folding SONiC into a variety of its Tofino-based bare metal switches.

Open Source NOS Demos At the OCP Summit

From sdxcentral: Facebook, Google, and Big Switch Networks at this week’s Open Compute Project (OCP) Summit will demonstrate three approaches to network operating systems all built with Open Network Linux (ONL) and all running on OCP switch hardware. All built with ONL is interesting to me. This is making the case ONL is simply an underlying Linux distribution. Why this wasn’t clear to me before is because of the poor messaging around all of these projects.

Open Source NOS: Response

My blog post on dNOS caused some interesting discussions to happen. My thinking was most people, be they open source people or networking people, don’t care about open source network operating systems. I have my theories as to why, and this Twitter thread contains my thoughts: I'm beginning to think my assumption most people don't care about open source network operating systems is valid. — Kyle Mestery (@mestery) March 14, 2018 It could also be that some of them are initially marketed as open source but with a long lead time until the code is released for public consumption.

dNOS: Another Open Source Network Operating System

This, from an AT&T press release at the end of January: AT&T* is working to provide the industry with a more open, flexible and cost-effective alternative to traditional integrated networking equipment. We intend to open source a project that we call the Disaggregated Network Operating System, or dNOS, hosted by The Linux Foundation. So far so good. Another network operating system, which is also open source, but I’m following along.
