Routing determines the path IP packets follow from source to destination. It is used in packet-switched networks like the Internet. Different routing methods are used to optimize speed, reliability, and performance.
Routing is the process of selecting a path for traffic in a network or between or across multiple networks. Broadly, routing is performed in many types of networks, including circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet.
