Shortest path algorithms are applicable to IP networks and widest path algorithms are useful for telephone network dynamic call routing and Quality-of-Service (QOS) based routing two classes of routing algorithms shortest path routing and widest path routing are the most widely used. |

Network design experts have developed the hierarchical network design model to help develop a topology in discrete layers. |
|
Although the model was developed at a time when routers delineated layers, the model can be used for switched networks as well as routed networks. |
|
The distribution layer connects network services to the access layer, and implements policies regarding security, traffic loading, and routing. |
|
Dijkstra's algorithm is a well-known shortest path routing algorithm. |
|
Open Shortest Path first (OSPF)OSPF an interior gateway routing protocol developed for IP networks based on the shortest path first or link-state algorithm. |
|
Routers use link-state algorithms to send routing information to all nodes in an internetwork by calculating the shortest path to each node based on topography of the Internet constructed by each node. |
|
Dijkstra's shortest path first algorithm and the Bellman–Ford algorithm are extended and are considered in widest path algorithm. |
