Linux Kernel Networking Overview - Rami Rosen

Abstract

A walkthrough of a packet in the kernel network stack, through layer 2, (the link layer), layer 3 (network layer) and layer 4 (transport layer).
The routing table and the routing cache.
The neighboring subsystem: arp table and arp cache.
The bridging subsysetm.
ICMP error messages.
A short survey: future trends in Linux Kernel Networking.

Note: The link layer (L2) we will discuss will be ethernet, and the network layer (L3) will be IPv4
