OSI Model

OSI model(open system interconnection)存在的原因: 网络模型建立是为了是网络的建造者可以建造出可以相互交流和一起工作的网络,并且描述了从一个电脑上通过网络传数据到另一个网络. 1.physical层 定义了对终端系统之间的连接的电子性和功能性,包括电压层级,物理距离,传输率,电压变化的周期等相关因素. 2.data link层 提供了依赖物理链路可以进行数据的传输,包括物理寻址,网络拓扑,网络访问,流控制. 3.network层 当需要路由时,提供了网络寻址

2. The OSI Model and the TCP/IP Protocol Suite The layered model that dominated data communication and networking literature before 1990 was the Open Systems Interconnection (OSI) model. Everyone believed that the OSI model would became the ultimate

International organization for standardization(ISO) developed a reference model for open system interconnection(OSI). The OSI reference model partitioned the communication process into seven layers and provide a framework for talking about the overal

计算机网络基础——OSI七层网络模型 OSI的是什么: 开放式系统互联通信参考模型(英语:Open System Interconnection Reference Model,缩写为 OSI),简称为OSI模型(OSI model),一种概念模型,由国际标准化组织提出,一个试图使各种计算机在世界范围内互连为网络的标准框架.定义于ISO/IEC 7498-1. OSI模型分为七层,建立七层模型的主要目的是为兼容不同的网络,通过将服务.接口.协议三个概念进行区分,使得不同系统不同的网络能实现可靠通
