According to a first aspect of the invention, there is provided a system for optimising data communication between devices connected to a network, the system including: a server configured to: measure application performance metrics of the data communication between the devices; compare the application performance metrics against performance requirements; detect, in response to the application performance metrics being below the performance requirements, nodes having untapped computing resources within the network; determine operation parameters achieving service at the performance requirements; command one or more of the nodes to function at the operation parameters; and migrate at least a portion of workload associated with the data communication amongst the one or more nodes commanded to function at the operation parameters.
