A Comparative Study of OSPF and EIGRP Dynamic Routing Protocols Through Simulation
During the last decades people have become witnesses to the rapid expansion of data networks. Modern networking has changed the way we work, study, play and communicate. It has also an important impact on health information systems, with their specific demands: availability, high performance, security. Dynamic routing protocols are crucial for the infrastructure to meet the business requirements.
The present thesis focuses on the two most important modern interior gateway protocols, OSPF (Open Shortest Path First) and EIGRP (Enhanced Interior Gateway Routing Protocol), which monopolize the market, as more or less industry standards. They are as well configured on most health information networks. Both operate inside an autonomous system, and while having different ways to form relationships among routing devices, adapt to topology changes and handle failures, they provide the same results: robust routing tables and network stability.
The objective is to undertake a comparison, both in theory and in practice, by means of simulation. After the initial study of the two protocols, simulation scenarios are implemented in the Riverbed Modeler environment. A set of measures is taken and comprehensive results are produced. As for the scenarios implemented, a slight superiority of the EIGRP protocol can be concluded.
In Health Information Systems there are many time-sensitive services and applications, such as remote monitoring of the status of the patient. In such cases, high-performance network infrastructures are required, which can be achieved, among others, by the appropriate selection and configuration of the dynamic routing protocol.
