Network management remains the least understood aspect of networking.Researchers have been successful in devising a set of Internet communication protocols,and the networking industry has developed a diverse set of innovative systems that canprocess packets at high speed. Meanwhile, network management relies heavily on hu-man ingenuity to diagnose problems and manual intervention to repair problems.
Commercial success has exacerbated the situation. On one hand, increased demandfor network services means that networks continue to expand. On the other hand, highdemand has created an environment that stimulates vendors to develop innovative pro-ducts and technologies. Thus, expansion results in significant changes becausemanagers tend to incorporate the latest network elements and mechanisms. Consequent-ly, networks include a diverse set of technologies that have been combined in an ad hocmanner, which means the resulting infrastructure is often haphazard.
网络互联的下一个时代将主要关注自动规划、配置。控制以及操作计算机网络和互联网。本书论述了自动化网络管理面临的挑战，评论了现有的管理工具和技术，并预见了自动化管理的未来。
Comer博士指出自动化既是对人类智力的挑战，其中又暗藏着巨大的商机。该书详细论述了目前网络难以管理的原因以及提高自动化程度的重要性，还阐述了标准FCAPS管理模型，列举了当前最重要的网络管理技术，并估计了其性能和局限性。
Comer博士认为创新(从新兴的体系结构到信息表示和语义上的改进)能够让自动控制更加有效。基于当今网络发展的实际情况，他标识出一个完整的自动化管理系统的特性，主要包括：
基础和定义：网络元素、服务器，差错管理。配置、记账、性能和安全。
基于自动化网络管理的关键概念，包括源自大规模分布式系统的思想。
现有的技术：集成平台，SNMP、NetFlow，路由和拥塞管理、scriting。
高级自动控制中的现实目标和工程的权衡。
用于自动化网络管理和表示网络站点的软件体系结构。
开放性问题和研究的难点。
