Each layer represents a specific set of functions and services that facilitate communication between devices and applications in a network. The OSI model serves as a reference for understanding and designing network protocols and systems. Here are the seven layers of the OSI model, listed from the lowest (Layer 1) to the hig… text/html 2023-10-19T09:57:00+00:00 Anonymous (anonymous@undisclosed.example.com) https://atrc.net.pk/dokuwiki/doku.php?id=products:ict:networking:routing&rev=1697709420&do=diff Network routing is a fundamental concept in computer networking that involves the process of determining the best path for data packets to travel from their source to their destination. Routers and routing protocols play a critical role in directing network traffic and ensuring that data packets reach their intended endpoints.

SDN introduces a centralized controller that manages the network and makes decisions about how to route traffic. This separation of control and data planes provides several advantages, including increased network agility, flexibility, and programmability.

Switches are devices that perform network switching functions. They operate at Layer 2 (Data Link Layer) and Layer 3 (Network Layer) of the OSI model and are used to connect devices such as computers, servers, printers, and other networked devices. Here are key aspects of network switch…
