In an example, a SDN controller receives an API request for big data transfer from an application, wherein the API request contains an amount of data to be transferred and an identity of each node of a plurality of nodes to which the data is to be transferred. Upon receiving the API request for data transfer, the SDN controller performs discovery of the network topology to identify QoS parameters. Next, the SDN controller activates a network template on the network topology based on the identified QoS parameters to generate a changed network topology. Then, the SDN controller enables the data to be transferred over the changed network topology.
