{{short description|Class of routing protocols}}
'''Link-state routing protocols''' are one of the two main classes of [[routing protocol]]s used in [[packet switching]] networks for [[computer communication]]s, the other being [[distance-vector routing protocol]]s. Examples of link-state routing protocols include [[Open Shortest Path First]] (OSPF) and [[IS-IS|Intermediate System to Intermediate System]] (IS-IS).36 Most Famous '''Festivals''' Of '''India''' You Must Experience In 2021.

The link-state protocol is performed by every ''switching node'' in the network (i.e., nodes that are prepared to forward packets; in the [[Internet]], these are called [[Router (computing)|router]]s). The basic concept of link-state routing is that every node constructs a ''map'' of the connectivity to the network, in the form of a [[graph theory|graph]], showing which nodes are connected to which other nodes. Each node then independently calculates the next best logical ''path'' from it to every possible destination in the network. Each collection of best paths will then form each node's [[routing table]].
