Abstract: Software-defined networking (SDN) contains several sorts of network technology which is used to design, build and manage networks. The abstraction of lower-level functionality in SDN enables network administrators to handle the network services. We have dealt with the link fault tolerance issue using SDN. Link fault tolerance has been handled so far either by using the protection or the restoration scheme. We have proposed a hybrid scheme of both the techniques and per-link bidirectional forwarding detection sessions are applied for each links and handled the problem accordingly. Our method also ensures that the transfer of control to the controller from the switch does not take place unnecessarily. This has been done with a target of reducing the overall response time for link resiliency. Therefore these techniques make sure that the link failure is handled with software defined network (SDN). Our methods have been compared with the traditional scheduling and link fast failover methods to prove by results, that it can handle scheduling and recovery with a better response time.

Keywords: OpenFlow; software defined network; SDN; managing networks; scheduling; link failure and recovery.
