Beginner's Guide 1. Overview of Routers Routers are indispensable devices in modern networks, responsible for forwarding data packets between multiple networks. In simple terms, routers are critical nodes connecting various networks and capable of data transmission at the network layer. 2. Basic Functions of Routers The main functions of routers include connecting internal and external networks, data packet forwarding, routing selection, and traffic control. Among them, routing selection refers to the automatic selection of the best path for data packet forwarding by the router based on different network protocols and according to some optimized method.
