So, in this article, we will see about the OSI model and it’s seven layers. Therefore, read this article if you need to understand what the OSI model is all about. OSI had two major components, an abstract model of networking, called the Basic Reference Model or seven-layer model, and a set of specific protocols. The OSI reference model was a major advance in the teaching of network concepts. It promoted the idea of a consistent model of protocol layers, defining interoperability between network devices

This article categorizes different network functions into different layers of the OSI model. While essential for understanding how packets move through a network, the OSI model itself is not a strict requirement as much as it is a conceptual model — not every protocol will fit perfectly within a single layer of the OSI model. The main aim of Network layer in OSI Reference Model is to deliver packets from source to destination across multiple links (networks). Here we have listed all the functions performed by the Network layer.

19/12/2008В В· It was developed as part of the Open Systems Interconnection ( OSI ) initiative. In its most basic form, it divides network architecture into seven layers which, from top to bottom, are the Application, Presentation, Session, Transport, Network, Data-Link, and Physical Layers. It is therefore often referred to as the OSI Seven Layer Model OSI had two major components, an abstract model of networking, called the Basic Reference Model or seven-layer model, and a set of specific protocols.
