OSI参考模与TCP／IP模型的异同及关联

OSI参考模型和TCP／IP模型作为计算网络发展过程中影响力较大的两大模型，它们有许多共同之处，但又有很大的区别并各有特点。本文从这两个模型层次结构、层次间关系、各自功能、数据传输原理这四方面入手对此分析两者异同，找出二者关系，从而对OSI参考模型和TCP／IP模型两个模型有更清晰的认识。

The Difference and Relationship between OSI Reference Model and TCP/IP Model

The OSI reference model, and the TCP/IP model for calculating network development process of two models, they have a lot in common, but also has the very big difference and have different features. Based on the two models, the relationship between the hierarchical structure, function and data transmission principle the four aspects of the comparison and analysis between the similarities and differences between the relations, so as to find the OSI reference model, and the TCP/IP model of two models are more clear understanding.
