Fundamentals of Routing: How Data Travels Across Networks
Routing: A Fundamental Concept in Networking routing market size is estimated to be valued at USD 15.1 billion in 2022 and reach USD 22.9 billion by 2027 , at a CAGR of 8.6% from 2022–2027. Routing is a critical process in networking that involves determining the best path for data to travel from a source to a destination across interconnected networks. In the context of the Internet and other large networks, routing ensures that data packets reach their intended destination efficiently, despite the complexity and scale of modern network infrastructures. How Routing Works When a device sends data over a network, the data is broken down into smaller units called packets. Each packet contains a destination IP address, which routers use to determine the packet’s next hop on its journey. Routers are specialized devices or software functions within a network that forward these packets from one network segment to another, making decisions based on routing tables. Routing Tables : A rout
