In this paper, we propose and experimentally evaluate a novel automatic network failure recovery mechanism based on Software Defined Networking (SDN). We demonstrate the introduction of services in this network with a reserve controller. The implemented architecture is setup to enable an efficient failure recovery mechanism in a way, in which reserve controller executes only in case of a main controller failure. Upon failure, the main controller automatically shifts control to the reserve controller for performing the computations of server load balancing and automatic bandwidth allocation until the main controller failure gets resolved. Experimented results show the estimated failure recovery time up to 24 ms.
