----千兆位以太网技术使主干网的速率得以大大提高，它是改善交换机与交换机之间和交换机与效劳器之间连接的可靠、经济的途径。网络设计人员能够利用它建立有效使用高速、任务关键的应用程序和文件备份的高速根底设施。网络管理人员可以为用户提供对效劳器区、Intranet/Intranet与广域网的更快速的访问。千兆位以太网具有性能价格比好、易于升级和管理、保护投资等特点，这些正是国图网络所需要的。
----网络系统选用了3Com公司的CoreBuilder 9000做骨干交换机。CB 9000千兆以太网交换机遵从标准的网络协议，为基于TCP/IP协议的应用提供透明的网络平台，同时提供

效劳质量〔QoS〕策略效劳，不需要对应用进行特别的修改，在以太网上实现多媒体等实时应用。另一方面，CB9000支持标准的局域网仿真协议，为基于以太网TCP/IP协议的应用提供完全兼容的环境。同时基于ATM的多媒体应用，可以在ATM环境下实现高品质的效劳质量保证。
设计方案
----国家图书馆的网络建设包括图书馆本身的馆域网以及实现与中国科技网、中国教育与科研网、Chinanet、广电网、北京大学、清华大学等网络的互联。
----国家图书馆的馆域网采用了千兆以太网为主干，独享10M到桌面的星形结构。从数字图书馆的实际出发，馆域网不仅要传送文本，还要支持大量的多媒体
