Interesting. I always suspected something like this was going on. Virtual networking / "SDN" just sounded slow to me.
Do you know a good source, to learn about the lower-level Linux/container/docker/k8s networking?
- zamadatix 6y agoI got the most value poking around with network namespaces manually via the "ip" command. There are also true VRFs in Linux these days which are much lighter but not nearly as common, most everything is a namespace with either bridging or NAT and some fancy configuration interface to drive that state.
- cheeseprocedure 6y agopackagecloud's in-depth writeups on the Linux networking stack are a great read: https://blog.packagecloud.io/eng/2016/06/22/monitoring-tuning-linux-networking-stack-receiving-data/ https://blog.packagecloud.io/eng/2016/06/22/monitoring-tunin... https://blog.packagecloud.io/eng/2017/02/06/monitoring-tuning-linux-networking-stack-sending-data/ https://blog.packagecloud.io/eng/2017/02/06/monitoring-tunin... The illustrated guide to receiving data is also solid: https://blog.packagecloud.io/eng/2016/10/11/monitoring-tuning-linux-networking-stack-receiving-data-illustrated/ https://blog.packagecloud.io/eng/2016/10/11/monitoring-tunin...
