Link-State Protocols are a type of routing protocol used in computer networks to determine the best path for data to travel. Unlike distance-vector protocols, which share information about the distance to destinations, link-state protocols share information about the state of each link in the network. This allows routers to build a complete map of the network topology, enabling them to make more informed routing decisions. One of the most common examples of a link-state protocol is Open Shortest Path First (OSPF). In OSPF, each router sends updates about its directly connected links to all other routers in the network. This ensures that all routers have a consistent view of the network, leading to efficient and reliable data transmission.
