Networking. At DevOps Networking Forum 2016, I had the opportunity to share a presentation on some Linux networking options. Here’s another topic that came up at the recent DevOps Networking Forum: Spotify’s SDN Internet Router (SIR). Here’s some information on Nuage Networks’ experimental Docker Network plugin.

First up is a treatise from Mircea Ulinic on whether network automation is needed. I first ran into Forward Networks a few years ago at Fall ONUG in New York.
