01
VOL 01 From the wire to the kernel.Explains how modern servers move packets through NIC silicon, PCIe, DMA, descriptor rings, and kernel data paths.
-
02
VOL 02 Above the kernel, into the guest.Explores five packet paths from kernel to VM guest via virtio, vhost-net, vhost-user, SR-IOV, and vDPA mechanisms.
-
03
VOL 03 Containers, namespaces, and the rule tables.Explores pod network isolation through namespaces, veth pairs, bridges, and netfilter rules, covering iptables scaling limits and cross-node packet paths.
-
04
VOL 04 CNI strategic. The fabric, the dataplane, the mesh.Explores eBPF-based CNI design, identity-based policy, and the convergence of service mesh with container networking.
