Description
eBPF has been here for a while, it allows us to extend the capabilities of the kernel without changing the kernel source code. This brings us extensible high-performance networking and load-balancing with very low overhead especially when using XDP hook. Sometimes it can be comparable performance-wise with libraries like DPDK, but for packet processing/receiving and compatible with kernel's TCP/IP stack. This talk shows the impact this can have on companies like Seznam.cz where IPVS has been used for a long time and what eBPF/XDP based replacement brings us. See for yourself.
