Survey on the Open Shortest Path First (OSPF) Routing Protocols

Abstract: Open shortest path first (OSPF) is the most commonly used intera-domain routing protocol. Open Shortest Path First (OSPF) is a link state routing protocol. In exiting different type of routing protocols can be extant, but the most well-known routing protocols are Routing Information protocol (RIP) and the Open Shortest Path First (OSPF). In this paper, surveyed OSPF protocols and algorithm. OSPF router saves path of the state of all the various network connections (links) between itself and a network it is trying to send data to. This makes it a link-state routing protocol. Open Shortest Path First (OSPF) is one of the most broadly used intra-domain routing protocol. The OSPF protocol does not provide efficient routing in terms of packet sending to achieve any network optimization neutral. The high cost of network assets and profitable and modest nature of Internet service provisioning. The service providers are absorbed in performance optimization of their networks. This help to reducing congestion network and improving resource consumption across the network, which, in turn, results in an increased income collection. One way of achieving this is through Traffic Engineering.
