Things have changed a little around here since the last time the three of them were chatting together on the podcast but one thing hasn’t, how much they love to talk all things open networking. In this episode the group talks about how to navigate the open networking operating systems space. From figuring out how to choose an open network operating system, to understanding what works best for deployments, and even what resources and communities are out there for you to tap into. We have it all here for you to help you get started.
