Reroute

Reroute is a verb describing the act of changing the planned or established course of travel, traffic, or communication to a new route.

In transportation and traffic management, rerouting occurs to avoid congestion, accidents, construction, or weather. Real-time traffic systems and road signs may propose alternate paths; detours become the new route for a trip.

In computer networks, rerouting refers to selecting an alternate path for data when the primary path fails or becomes suboptimal. Routing protocols such as OSPF, EIGRP, and BGP enable reroute by updating routers' tables and redistributing paths.

In logistics and operations, rerouting can involve changing the itinerary of shipments, flights, or vessels due to factors like port closures, capacity limits, or emergencies. The goal is to minimize delays and maintain service levels.

In software and systems, rerouting may describe redirecting a process, service, or input stream to another handler or worker, such as load balancing or error handling.

Reroute is related but distinct from redirect, which usually means signaling a destination change rather than physically changing the path; a detour emphasizes a temporary deviation along a longer or blocked route.
