Dijkstra Algorithms
To calculate its routing table each router applies an algorithm called the dijkstra algorithm to its state database. The dijkstra algorithm calculates the shortest path between two points on a network using a graph using a made up of nodes and arcs. Notes are of two types networks and routers. Arcs are the connection between a router and a network ( router to network and network to router). Cost is applied only to the are from router to network. The cost of the from network to router is always zero .
