对开放系统互联OSI有关重要概念的分析

An Analysis of the Important OSI-Related Concepts

不可否认服务（Non-RepudiationService）是开放系统互联参考模型安全体系结构标准ISO/IEC7498-2中描述的五种安全服务之一。

Non-repudiation service is one of the five security services described in ISO / IEC 7498-2 which is known as Security Architecture of Open Systems Interconnection-Basic Reference Model .

但从开放系统互联参考模型（OpenSystemInterconnectReferenceModel，简称OSI）的角度来看，CAN现场总线底层协议仅定义了物理层（第一层）和数据链路层（第二层），没有定义应用层。

But from the point of view of Open System Interconnect Reference Model ( OSI for short ), CAN field bus low-level protocol defines physical layer ( the first layer ) and date link layer ( the second layer ), without including the application layer .

现在，随着民航业务的飞速发展，基于开放系统互联（OSI）模型的航空电信网（ATN）逐渐显示出了它的不足。

Now , as the rapid development of civil aviation , the deficiency of Aeronautical Telecommunication Network ( ATN ) based on the Open System Interconnection ( OSI ) model , becomes more and more obvious .

对开放系统互联参考模型和TCP/IP协议分层体系结构进行了分析，论证了所采用方法的可行性。

The Reference Model of Open Systems Interconnection and TCP / IP Protocol System are also analyzed in this paper , which prove the feasibility of this method .

本文论述了开放系统互联安全体系结构下的重钢信息网络安全现状分析和风险评估；

The article deals with the current analysis and risk evaluation of CISC ( Chongqing Iron and Steel Company )' s information internet security under the opening systematic co-action secure structure .

在两种著名的网络协议模型中，OSI开放式系统互联参考模型得到了全世界的认同，但互联网历史上和技术上的开发标准都是基于TCP/IP（传输控制协议/互联网协议）模型的。

There are two well-known network protocol models , OSI reference model and the TCP / IP . Although the OSI reference model are popular all over the world , the TCP / IP protocol is the actual standard .

对管理信息化相关理论、开放式系统互联（OSI）参考模型和网络安全体系结构进行了回顾，对信息安全技术手段和常用网络安全产品资料进行了收集和整理，以此为理论依据展开论文的研究。

Reviewed the correlation theories for management informationization , the Open Systems Interconnection ( OSI ) reference model and the network security architecture . Collected and reorganized the information security technology method and the commonly used network security product material . Above content all is the paper research theory basis .

然后，讲解了计算机网络技术基础的核心理论&ISO/OSI开放式系统互联参照模型。

Then , the paper states the core theory of networking essence , the Reference Model of Open System Interconnection published by ISO / OSI .

无线传感器网络采用类似开放式系统互联模型的协议栈。由于传感器网络的自身特点使得传统网络的一些协议不能直接应用，必须研究新的协议来替代。

The wireless sensor networks ( WSNs ) uses the network stack which is similar with the OSI model , but due to the unique characteristics on the WSNs , it is necessary to develop some new protocols to instead the traditional network 's.
