Technical solutions for optimization of network resources are described. One general aspect includes a method, including measuring, by a controller, an attribute of network route being used to communicate a network flow between a first apparatus and a second apparatus. The method also includes comparing, by the controller, a predetermined threshold and the attribute. The method also includes in response to the attribute being non-compliant with the predetermined threshold, selecting, by the controller, an alternative network route to communicate the network flow between the first apparatus and the second apparatus. The method also includes routing, by the controller, the network flow to be communicated via the alternative route between the first apparatus and the second apparatus.
