This focus limits experimentation and realism of legacy Ethernet network (LEN) protocols used, for example, in dynamic routing. In this paper, we develop an extension to Mininet’s functionality using Free Range Routing (FRRouting) protocol suite to enable the emulation of standard, open dynamic routing protocols, particularly Open Shortest Part First (OSPF). FRRouting can run within a network namespace and Mininet nodes are essentially network namespaces. We have incorporated FRRouting into a Mininet topology and investigated the operations of the dynamic routing protocol, OSPF. We found that dynamic routing protocols behaviors such as fault tolerance, routing convergence, and router solicitation can be effectively investigated using this integration.FulltextenMininetSoftware Defined NetworksSDNSDN MigrationRouting protocolsHigh-fidelityLegacy networksEmulationConference PresentationN/A
