SONiC is a network OS that can run on a variety of whitebox switches. Originally developed by Microsoft, SONiC is now an open-source project with distributions that target hyperscale and enterprise environments. Today's Heavy Networking is a deep dive into SONiC with Dave Maltz, a Technical Fellow at Microsoft who has been closely involved with SONiC's development. While Microsoft is a SONiC backer, this is an unsponsored episode.
