Welcome to the “Networking” microconference of Plumbers 2016. This track was named “Network Virtualization” in previous years. Upon request we are opening up the spectrum for this year. We have however decided to define a list of interesting networking topics that we want to focus on. We will therefore favour discussion topics which fall into the following list of topics:

  • IPv6
  • Network Virtualization
  • Security

As in previous years, we are enforcing a hard limit of 3 slides per presentation to ensure focus on discussion over monologues. Marketing pitches will not be tolerated and will be shut down. (If you feel the urge to put your company logo onto slides you are probably in the wrong room anyway)

If you are interested in presenting on this topic then please list yourself in the section “Proposed Topics” below.

Topics of Interest

  • Network Virtualization
    • Preparing the network stack for multi tenant container clusters
    • Reducing the weight of network namespaces
    • Improved VRF implementation - netns + ip rules? nft?

    • Programmable data path (tc cls/act, eBPF, OVS, nft, …)
    • Encapsulation, overlays, service chaining (VXLAN, Geneve, GUE, NVGRE, NSH, …)
