Rerouting is the process of changing the path or direction of a vehicle, data, or information flow to reach a destination more efficiently. This can occur in various contexts, such as when a GPS system recalculates a route due to traffic or road closures, guiding drivers to an alternative path. In technology, rerouting can refer to redirecting network traffic to avoid congestion or improve performance. For example, when a web server experiences high demand, rerouting can distribute requests to other servers, ensuring that users receive a smooth experience without delays.
