With danm it is possible to allocate multiple network interfaces to the pods. Danm is metaplugin plus infrastructure in kubernetes. You can control network interface attachment via pod manifest’s annotations. This presentation is a little bit deeper dive how it is working in real life.

Ebpf is a “renewal” of classic bpf (berkeley packet filtering) which is in kernel since 2.5. In 2011 JIT was introduced, in 2014 with e newer JIT ebpf was born. One of the evolution techniques that it introduced, was decoupling from networking. However, this presentation is still about networking, an introduction to ebpf/xdp via examples and possible usage scenarios inside kubernetes.
