Introduction

Routing algorithms: Routing algorithms are algorithms that are used to determine the best path for data to travel in a network. These algorithms are used to find the most efficient route for packets of data to traverse from the source node to the destination node. Different algorithms are used depending on the type of network in use, the type of data being sent, the size of the network, and the amount of traffic.

Common routing algorithms include distance-vector routing, link-state routing, and path-vector routing. Distance-vector routing algorithms work by calculating the distance between two nodes to determine the best path for data to travel. Link-state algorithms use the flooding technique to share information about the entire network, while path-vector algorithms use a vector to store the paths taken by data.
