内容简介

  Linux如此的流行正是得益于它的特性丰富并有效的网络协议栈。如果你曾经惊叹于Linux能够实现如此复杂的工作,或者你只是想通过现实中的例子学习现代网络,《深入理解Linux网络内幕》将会给你指导。同其他O'Reilly的流行书籍一样,《深入理解Linux网络内幕》清楚地阐述了网络的基本概念,并指导你如何用C语言实现。虽然早先的TCP/IP经验是有用的,但初学者通过本书仍然可以学习到协议本身和大量的应用信息。一旦彻底掌握了这些网络工具,你就可以使用本书所附的代码,准确地指出Linux内核中最重要的部分如何工作。 网络功能的实现或破坏在不同的时候是由不同的代码块完成的,这正是理解网络和实现它的难点中的一部分。本书的成功之一就是描述这些代码块如何集成,以及众多的函数和数据结构之间的关系。《深入理解Linux网络内幕》不仅描述了Linux网络的全貌,而且是理解Linux网络细节的有效指南。 作者Christian Benvenuti是一个专注于操作系统网络的设计者。他在书中不仅解释了Linux代码如何工作,还阐述了主要网络特性的目的以及在不同解决方案间是如何抉择的。书中还包含了大量的流程图和其他图表以帮助读者理解。 书中的主题包含:·网络通信的主要问题·网络接口设备(NIC)驱动·系统初始化·第二层(链路层)的功能和实现·第三层(IPv4)的功能和实现·ARP·桥接·路由·ICMP
