内容简介
局域网（LAN）正经历着一个大转变，其标志是从传统的集中器（HUB）和路由器（router）构成方式向基于交换的系统（如第三层交换）转变。作为新的网络的设计者或网络管理者，需要从繁杂的新技术中理清头绪，并从众多厂商中选择满意的产品，本书既是介绍大规模交换式网络新技术的专著。 本书在内容上包括LAN交换的基本概念、交换式LAN的设计原则，交换式网络的规模可扩展性问题；同时就交换式网络中的网络协议作了深入细致的分析，这些协议包括IP协议、Novell Netware以及其他协议，如IPX/Net beul等。此外还详细阐述了动态主机配置协议（PHCP），并对交换式网络的维护和故障处理，以及虚拟局域网（VLAN）和远程监控（Rmon）等技术作了描述。 本书适合于计算机和网络通信专业的研究生和本科生阅读，也可以作为从事计算机网络设计与管理方面的广大科技工作者的参考用书。
