Distance Vector Routing
Distance Vector Routing is a dynamic routing algorithm used in computer networks, particularly in routing protocols like RIP (Routing Information Protocol). It operates by having each router maintain a table (the distance vector) that lists the best known distance to each destination and which neighbor to use to get there. Routers periodically exchange their entire routing tables with directly connected neighbors, allowing the network to converge on optimal paths based on metrics like hop count.
Developers should learn Distance Vector Routing when working on network infrastructure, especially in small to medium-sized networks where simplicity and low overhead are priorities, such as in LANs or legacy systems. It's essential for understanding basic routing principles, troubleshooting network protocols like RIP, and grasping foundational concepts in distributed systems and algorithm design for routing.
