Bringing the Power of eBPF to Open vSwitch

Bringing the Power of eBPF to Open vSwitch

Explore the challenges and experiences of integrating eBPF with Open vSwitch (OVS) in this Linux Plumbers Conference talk. Dive into three approaches: attaching eBPF to TC, offloading processing to XDP, and bypassing the kernel with AF_XDP. Learn about the limitations encountered, workarounds implemented, and ongoing efforts to enhance OVS functionality using eBPF. Discover the trade-offs between different layers of packet processing, from TC to XDP, and understand the potential of AF_XDP for userspace implementations. Gain insights into the future direction of OVS development and the role of eBPF in improving network virtualization performance.
