摘要
计算机网络体系结构描述了计算机网络功能实体的划分原则及其相互之间协同工作的方法和规则。随着网络技术和应用的不断发展,目前广泛使用的层次型网络体系结构逐渐暴露出了部分问题,这就催生了各种新型网络体系结构的研究和尝试。本文在引出计算机网络体系结构定义的基础上,着重讨论了目前已经出现的层次型网络体系结构、面向对象网络体系结构、基于角色的网络体系结构和服务元网络体系结构四种网络体系结构的发展过程及其特点,并在最后对网络体系结构的发展方向进行了展望。
Network architecture is a set of high-level design principles that guides the technical design of the net- work, especially the engineering of its protocols and algorithms. With the rapid development of the network technolo- gies and applications, the layered network architecture, which is widely used at present, has been exposed several problems gradually. Accordingly there are lots of researches about the novel network architectures. Based on intro- duced the definition of the network architecture, this paper focuses on the develop processes and characters of the cur- rent existent four network architectures, which are layered network architecture, object oriented network architec- ture, role-based network architecture and service-unit based network architecture. The network architecture prospect is also discussed at the end of this paper.
