Linux Network Stack Walkthrough 2 6 The Linux kernel provides three basic structures for working with network packets struct socket struct sock and struct sk buff The first two are abstractions of a socket struct socket is an abstraction very close to user space ie BSD sockets used to program network applications

Common Functionality in the 2 6 Linux Network Stack 7 Linux Network Stack The basic network stack model which Linux adopted from the TCP IP stack has four basic layers as shown in Figure 2 Figure 2 Basic layers of the Network Stack The application layer runs usually in user space such as telnet or FTP client This document is a guide to understanding how the Linux kernel version 2 2 14 specifically implements networking protocols focused primarily on the Internet Protocol IP It is intended as a complete reference for experimenters with overviews walk throughs source code explanations and examples
