BPF, eBPF, XDP and Bpfilter… What are These Things and What do They Mean for the Enterprise?
You may have been following the development of the extended Berkeley Packet Filter (eBPF) in the kernel community since 3.15, or you may still associate the Berkeley Packet Filter with the work Van Jacobson did in 1992. You may have used BPF for years with tcpdump, or you may have started to plumb it in your data plane already!
