When a link failure occurs, OSPF protocol detects it using RouterDeadInterval time. This timer is fired only after a predefined time interval, thus increasing the time of convergence after the link failure. There are previous studies to reduce the RouterDeadInterval time, but they introduce other effects which are discussed later in the thesis. So, a novel approach is proposed in this thesis to reduce the link failure detection time with the help of emerging network architecture Software Defined Networking (SDN) and OpenFlow Protocol.en-USSoftware-defined networking (Computer network technology)OpenFlow (Computer network protocol)Computer networks -- Research -- AnalysisComputer-aided engineeringComputer-aided designSystem analysisComputer network protocolsComputer network architecturesRouters (Computer networks)LinuxOperating systems (Computers) -- Testing -- MethodologyThesis
