Abstract

The upper three OSI layers support the communication requirements of applications, while the lower four layers provide reliable transmission of data. This article describes the lower four layers. First, though, a brief overview of the layered model is presented including a summary of the upper three layers. Then a description of the lower three layers is followed by a discussion of data communication standards associated with specific layers. Architectural concepts are then explored hierarchy and abstraction within the layers, levels of dialogue, internetworking, endtoend communication, analysis of layer four, and a discussion of connectionoriented, connectionless, and messageoriented protocols and applications. The article concludes with a comparison of OSI and the de facto industry protocols, TCPIP, which are currently used within the Internet.
