afstandsvector

Afstandsvector, also known as distance vector, is a routing algorithm used in computer networks to determine the best path for data packets to travel from a source to a destination. It is a decentralized algorithm, meaning that each router in the network makes its own routing decisions based on information it receives from its neighbors.

The distance vector algorithm operates by each router maintaining a table, known as the routing table, which contains information about the distances to various destinations in the network. The distance is typically measured in terms of hops, which is the number of routers a packet must pass through to reach its destination. Each router periodically sends its routing table to its neighbors, allowing them to update their own routing tables.

One of the key features of the distance vector algorithm is its simplicity and ease of implementation. However, it also has some limitations. For example, it can suffer from the count-to-infinity problem, where routers may take a long time to converge on the correct routing information, especially in the case of network failures. Additionally, the distance vector algorithm can be inefficient in terms of bandwidth usage, as routers must periodically send their entire routing tables to their neighbors.

Despite these limitations, the distance vector algorithm has been widely used in computer networks, particularly in smaller networks where its simplicity and ease of implementation are advantageous. It has also been used as a basis for more advanced routing algorithms, such as the Path Vector algorithm, which includes additional information in the routing updates to help prevent routing loops and improve the efficiency of the algorithm.
