Answer: shortest path routing
Which routing protocol depends on the DUAL algorithm to calculate the shortest path to a destination
#include
Dijkstra
Dijkstra's algorithm is used by the OSPF and the IS-IS routing protocols. The last three letters in OSPF (SPF) mean "shortest path first", which is an alternative name for Dijkstra's algorithm.
The fastest algorithm for finding the shortest path in a graph is Dijkstra's algorithm.
OSPF (Open Shortest Path First) uses the Dijkstra algorithm, also known as the Shortest Path First (SPF) algorithm, to populate its routing table. It builds a link-state database (LSDB) that contains information about all the routers and their links within the OSPF area. By calculating the shortest path to each destination based on the cost of the links, OSPF determines the optimal routes for data packets. This allows OSPF to efficiently update its routing table and optimize network traffic.
OSPF stands for open shortest path first. OSPF is an exterior routing protocol. OSPF uses Path vector routing algorithm.
Dijkstra's algorithm has importance when you are trying to find the shortest path between two points. It's used in the computer networking field where routing protocols, like OSPF, uses it to find the shortest path between routers. http://en.wikipedia.org/wiki/Dijkstra%27s_algorithm
Link-state routing algorithms, also known as shortest path first (SPF) algorithms.
"OSPF detects changes in the topology, such as link failures, very quickly and converges on a new loop-free routing structure within seconds. It computes the shortest path tree for each route using a method based on Dijkstra's algorithm, a shortest path first algorithm."
