Routers are key elements of the Internet, and without routers there would be no Internet. They are highly secure and complex systems which run their own operating systems, and if operated correctly they can significantly improve the performance of interconnected networks. Their main function is to examine the network address of the data packets and decide the route that the data packet should take. To be able to determine the best route that the data packets should take they require routing protocols, such as RIP and EGP. These routing protocols allow routers to communicate with other routers so that they can determine the structure of the interconnected networks. A routed protocol is one that is routed through interconnected networks, such as IP.
