Abstract
Embodiments relate to software-defined networking (SDN) disaster recovery. An aspect is a system that includes an SDN controller configured to interface with a plurality of servers and switches in a network. The SDN controller includes processing circuitry configured to perform a method that includes establishing a plurality of flows, by the SDN controller, between a plurality of switches and pairs of servers in a network, including at least two different pairs of server types. Each server type runs a different operating system and a different disaster recovery manager in an active/active configuration. Data migration is controlled, by the SDN controller, between the pairs of servers in the network. The SDN controller dynamically reallocates the flows between the switches and the pairs of servers in the network based on detecting a fault in the network.
