Providing a detailed guide to implementing and using the Linux TCP/IP stack in embedded systems projects, this text begins with a general overview of the TCP/IP networking, with background information on applicable networking standards. After the basics are covered, the book takes programmers on a detailed tour of TCP/IP implementation in Linux and TCP/IP sources by following a packet of data as it flows through the stack from the sending system, out the wire, and back through the input side of the stack in the receiving machine. Throughout the text, specific real-time requirements, network management and memory constraints are covered in detail. This resource is aimed at embedded systems programmers and engineers, as well as networking professionals interested in learning more about the implementation of Linux TCP/IP.
