Usage of OSPF Convention in System Designed in Republic of Iraq

Abstract

OSPF is a very important internal entryway protocol that employed in web layer of TCP/IP model and in network layer in OSI model. OSPF is employed in application of current networks like impromptu wireless and mobile communication systems, in ISP, enterprise networks in colleges, hospitals…etc. it additionally employed in management plane of SDN. OSPF can management on call of that have the shortest path of network branches looking on their weights. Principle work of OSPF protocol verify the shortest path by checking link state of network. Also, principle of this protocol, it divides identical network into areas (sub networks).during this paper, OSPF network has one space referred to as (area 0), that has 6-Routers distributed among cities on Iraq’s map. MATLAB (2017b) and GNS-3 (2.1.3) softwares area unit wont to calculate theoretical and experimental results severally. The results evidenced that the most effective path that has the low weights and time period. These results additionally evidenced that if the shortest path is down, it may be used the opposite link (back up) within the network.
