Routing and Switching is the foundation of all networks. Proper IP addressing scheme, technologies used and wise equipment choice would guarantee a stable, scalable and fault tolerant network. Routed and switched networks resemble cities with highways, railways and airlines between them. When you need a package delivered you write an address and leave it at the post office. The post office routes the package further along the most optimal path to another office until eventually the package finds its recipient. The same principle lies within architecture of computer networks. Even now when you are reading these lines means your computer has got the package from my belongings with this very text you are reading. It was delivered to you in milliseconds via a network of routers and switches interconnected with optical fiber links around the world.
