摘要
正在试点的中国国家金融网络(CNFN),是一个基于开放系统结构的、支持国家级金融应用系统的数据通信网络。它采用模块化结构设计,物理网络分主干网和区域子网2层,并将向准网格状网络拓扑演进,网络层以X.25协议为基础并引入了帧中继技术。该网的网管系统和灾难恢复措施使网络具有较高的安全性。CNFN将全方位地为我国金融界广大用户提供各类数据通信服务。
The China National Financial Network(CNFN) is an open system architecture-based data communications network, supporting the national level financial application systems. It is designed with a modular structure, and its physical network consists of the backbone and regional subnetworks, and is evolving towards a quasi-grid network. The network layer is based on the X.25 protocol and adopts the frame relay technology. The network management system and disaster restoration measures have improved the network security. CNFN will provide various data communication services for the broad users in the financial circles in China.
