Reititykseen

Reititykseen is a Finnish term used in information technology and telecommunications to describe the process of determining and updating the routes that data packets follow through a network. It covers route discovery, selection, and maintenance, as well as the policies and constraints that influence route choice. The concept corresponds to the English term routing.

Practically, reititykseen involves static routing, where paths are manually configured, and dynamic routing, where protocols such as OSPF, IS-IS, RIP, and BGP enable automatic adaptation to topology changes. Key concerns include how routes are advertised, how routing tables are kept consistent, convergence speed, and scalability in large networks. Security considerations include preventing route hijacking and avoiding routing loops.

In modern networks, reititykseen is often implemented with software-defined networking (SDN) and centralized controllers that compute routes and distribute them to devices, improving agility and policy enforcement. The approach supports traffic engineering and multi-path routing but requires robust control planes and reliable authentication to prevent misconfigurations.

Outside pure networking, the term can appear in logistics and transportation planning to describe the routing of goods along routes to optimize cost and time. Related topics include routing, network protocols, traffic engineering, and SDN.
