Description: 计算校验和
校验和算法描述：为保证网络上传输的数据的可靠性，在许多协议中都设置了校验和项，例如：IPv4、ICMPv4、IGMPV4、ICMPv6、UDP和TCP 等等。计算这些校验和的算法称为网际校验和算法，简单来说就是：把被校验的数据１６位进行累加，然后取反码，若数据字节长度为奇数，则数据尾部补一个字节的０以凑成偶数。
由于从输入文件读入的数据不能直接满足计算校验和的条件，所以首先对从文件读入缓冲区的数据进行预处理，即读入缓冲区时忽略空格。由于累加是按16位进行的，所以每次从缓冲区中读出4个字符，并将字符转换成对应的16进制数字，如此依次累加，直至数据全部读完。
还有一种情况，即如果数据长度为奇数个字节，则需要判断，并补0累加。程序中利用的是缓冲区长度计数器i和当前读取到计数器j判断数据长度是否为奇数。即如果数据长度为偶数，则读完数据时当前读取到计数器j的值应与缓冲区长度i相等，而如果数据长度为奇数，则读完数据时，当前读取到计数器j>缓冲区长度i，此时需将缓冲区中剩余的两个字符读出，并补0，转换成相应16进制数以后参与累加。
当累加结束后，将累加和的16位以上数据位移下再进行一次累加，并对最后累加和取反即得所求校验和。

Description: 本书全面讲解IPv6及相关协议实现的事实标准KAME，揭示了KAME IPv6协议栈的所有细节，对每行代码到底做了什么以及为什么要这样设计都进行了解释。全书共分7章，分别介绍IPv6地址结构、IPv6、ICMPv6、邻居发现和无状态地址自动配置、传输层协议及套接字API扩展。每章都包含两个主要部分：第一部分提供了作为RFC发布的主要协议规范的摘要，定义各种协议分组，解释每个分组中每个字段的含义和目的；第二部分则描述实现这些RFC的KAME的数据结构及功能。书的最后还提供了一些例子，说明如何编写既可以在IPv4网络上运行、又可以在IPv6网络上运行的可移植应用程序。.
本书是IPv6的权威参考书，适合网络设计和开发人员阅读。此外，本书还适合作为高校相关专业网络课程的教学参考书。-This book fully explain the IPv6 and related protocols, the de facto standard KAME, reveals the KAME IPv6 protocol stack all the details on each and every line of code in the end did what and why to be so designed to have carried out an explanation. The book is divided into seven chapters, describing the structure of IPv6 addresses, IPv6, ICMPv6, neighbor discovery and stateless address autoconfiguration, Transport Layer and the socket API extensions. Each chapter contains two main parts: the first part provides as RFC published a summary of the main protocol specification, defining a variety of protocols grouped in each group to explain the meaning and purpose of each field second part describes the to achieve these RFC s KAME data structure and functions. End of the book also provides some examples to illustrate how to write both in IPv4 networks running IPv6 networks and can run in portable applications. .
