Power of OSI Layer Model

International Organization for Standardization (ISO) developed the seven-layer model or i.e call OSI(Open System Interconnection) Layer Model in 1984 to help vendors and network administrators so that they can obtain a better understanding of how data is handled and transported between two networking devices, as well as to give a guideline for the implementation of networking standards and technologies.

What is OSI Layer model

ISO developed OSI Reference Model that explains how data is transferred from one networking component to another, from the point when a user enters information using a keyboard and mouse that is converted to electrical or light signals transferred along a piece of wire (or radio waves transferred through the air). The OSI reference model is the primary model for network connections. The early development of LANs, MANs, and WANs was confused in many ways for this they added networks and expanded existing networks as rapidly as new network technologies and products were introduced. To assist in this process, the OSI Reference Model separates the network communication process into seven layers.

OSI Layer Model

Reduces complexity:
OSI Layer Model divides network communication process into smaller and simpler components, thus helping component development, design, and troubleshooting.

Systematize interfaces:
OSI Layer Model systematizes network components to allow multiple vendor development and maintenance.

Facilitates modular engineering:
OSI Layer Model supports various types of network hardware and software to talk with each other.

Interoperability between Vendors:
OSI Layer Model provides multiple-vendor development through standardization of network components. It defines the process of connecting two layers together, promoting interoperability between vendors. It allows vendors to compartmentalize their design tries to fit a modular design, which eases implementations and simplifies troubleshooting.

Ensures interoperable technology:
OSI Layer Model prevents changes in one layer from affecting the other layers, allowing for quicker development.

Accelerated evolution:
It gives for dynamic updates and improvements to individual components without affecting other components or having to rewrite the entire protocol.

Simplifies teaching and learning:
OSI Layer Model separates network communication into smaller components to make learning simpler. Provides an educational tool to help network administrators understand the communication process used between networking components.

OSI Reference Model

  • OSI reference model consists of seven layers: physical, data-link, network, transport, session, presentation, and application.
  • OSI model layers typically do not correspond exactly to the protocol stack running on an actual system.
    Data-link layer protocols usually involve physical layer specifications.
  • Network and transport layer protocols work together to give a cumulative end-to-end communication service.
  • Functions of the session, presentation, and application layers are often merged into a single application layer protocol.
