Month 4-Linux Networking: Netfilter, IPVS, XDP, Bridges, OVS¶

Goal: by the end of week 16 you can (a) trace a packet from NIC through XDP, the network stack, conntrack, iptables/nftables, sockets, and back, (b) configure a Linux bridge and an Open vSwitch flow, (c) write an XDP program that drops or redirects packets, and (d) reason about IPVS load-balancing modes.
