distancevectortyyppinen

Distance vectortyyppinen refers to a category of algorithms used in computer networking, particularly in routing protocols, that operate on the principles of distance-vector routing. In this approach, each router maintains a table that lists its known routes to other networks, including the estimated cost (or "distance") to reach each network and the "vector" or next hop router that should be used to forward packets towards that destination. Routers periodically exchange their entire routing tables with their directly connected neighbors. When a router receives an update from a neighbor, it compares the information with its own table. If a shorter path to a network is discovered through the neighbor, or if a previously known network becomes unreachable, the router updates its table accordingly. This process of sharing and updating information allows routers to collectively build a map of the network and dynamically adjust routes as network conditions change, such as link failures or the addition of new routers. Examples of distance-vector routing protocols include RIP (Routing Information Protocol) and IGRP (Interior Gateway Routing Protocol). While effective for smaller and stable networks, distance-vector protocols can sometimes suffer from issues like slow convergence times and the "count-to-infinity" problem, where routing information may take a long time to stabilize after a network change.
