摘要： 经过五年的建设和运行，中国教育科研网（ＣＥＲＮＥＴ）已经成为中国最重要的信息基础设施之一。本文提出了一种基于ＣＥＲＮＥＴ的三层网络信息服务体系构建框架，它由信息服务层、高性能服务支持层和高性能基础设施层构成。它们之间相互联系、相互依存．构成了从底层到高层、从硬件到软件、从局部到全网的“ＣＥＲＮＥＴ高性能网络信息服务体系结构框架（ＣＨＮＩＳＡ）”。该框架对ＣＥＲＮＥＴ下一步的建设和发展有着重要的参考价值。

Abstract: China Education and Research Network (CERNET) has become one of the most important information infrastructure in China after its five years developing and running. In this paper, three-tier network information service architecture based on CERNET is preseuted. It is composed of Information Service Layer, High-performance Service Support Layer and High-performance Infrastructure Layer, which depends on each other and has tight relationship. The laytrs construct the CERNET High- performance Network Information Service Architecture (CHNISA) from hardware to software and from local to whole network. The architecture has high reference value for CERNET's next step.
