link-state routing

Link-state routing is a method used by computers in a network to determine the best path for sending data. Each device (router) learns about the entire network’s layout by exchanging information with its neighbors. It then builds a detailed map of all connected points and the costs or distances to reach them. Using this map, each router independently calculates the shortest and most efficient route for data packets to travel from source to destination. This process ensures accurate, up-to-date routing decisions, leading to faster and more reliable network communication.
