Research Paper on Implementation of OSPF Protocol in MATLAB

Author Name : Pinky, Umesh Gupta

The OSPF is an open standard protocol that is most popularly used in modern networks. It is a link state protocol. Various protocols are used for shortest path. But in real life mostly problems are undirected graph like nature. OSPF using Dijkstra’s algorithm solved shortest path problem in both type of problems i.e. directed and undirected graph. Along with problems becomes more crucial when no. of undirected branches are more than no. of nodes (eg. in road map, electrical circuits, protein structure, Genetic Engineering etc.). This research wills find how OSPF routing protocols works for directed and undirected graph problem. Following are the reasons of using OSPF: 1) OSPF is not a CISCO proprietary protocol like EIGRP. 2) OSPF always determines the loop free routes. 3) If any changes occur in the network it updates fast. 4) Low bandwidth utilization. 5) Support multiple routes for a single destination network. 6) OSPF is based on cost of the interface.
