Ouvrage 9781578201082 : TCP/IP LEAN: WEB SERVER FOR EMBEDDED SYSTEMS 2ED

TCP/IP Lean should be listed in the 'What's New' page at the top of the 'Embedded
Systems' category
Key Benefits
Implement dynamic Web programming techniques for Web appliances.
Internet programming demystified! This is a hands-on guide to TCP/IP networking that
includes source code to a simple TCP/IP stack - a lean version that is easier to present
and efficient enough to use in embedded applications.
Create a small, stand-alone TCP/IP stack with an embedded Web server. Aided by the
author's abundant source code examples and fully-functional utilities, you will learn about,
and experiment with, the simpler aspects of internetworking, before tackling the TCP
protocol itself. The author offers an intensely practical approach, while still providing an
in-depth understanding of the TCP/IP protocol family. At each stage of the book, you will
consolidate your understanding through experimentation with suitable software utilities.
Along the road to mastering the creation of complex network software, you will:
learn about key networking and multimedia technologies
experiment with the code for fully-debugged protocol software
explore and extend the professionally-written software
employ ready-to-use utilities for simulating and testing networks
build the protocols from the ground up
speed your future network development with a powerful set of tools and utilities
meet the challenge of providing advanced Web features on low-cost embedded
systems
Embedded Web servers are the order of the day: _ industrial equipment and domestic
appliances are being designed with browsers to provide a user interface and remote
diagnostic capability. This book meets the challenge of implementing dynamic Web pages
on small-scale embedded systems, providing full 'C' source code for the PC hardware
platform and a PIC microcontroller.
Software provided on the accompanying CD-ROM is compatible with several popular 'C'
compilers to simplify desktop development.
Jeremy Bentham is co-founder of an industrial networking company (Io Ltd.) and its
software consulting offshoot Iosoft Ltd., in Cambridge, England. An engineer by training, he
has developed many computer systems in railway control and other industrial applications
and a wide range of software tools for embedded systems. Networking projects included
Bitup, a Bitbus emulation for the 80188 processor; data transfer protocols using Arcnet and
Ethernet; and a full 801888-based remote-boot communications system using the simpler
TCP/IP protocols (UDP and TFTP). Recent work has been in implementing embedded
TCP/IP systems in aerospace, air quality and video surveillance applications. In his spare
time, Jeremy enjoys playing racquet sports and is a keen amateur actor.
