Abstract

A computer implemented method of adapting a software defined network (SDN), the SDN operating with a set of network appliances in communication via network connections and the SDN comprising a control component operable in communication with at least a subset of the network appliances to control communication via the SDN, the method including receiving a representation of the logical arrangement of the SDN including a definition of appliances configured to provide communication for the SDN and network connections therebetween; receiving a measure of a performance metric for the SDN; receiving a forecast demand for the SDN; using a heuristic search to search a library of possible adaptations to the logical arrangement to identify a sequence of adaptations of the SDN that, when implemented, satisfy the forecast demand for the SDN and provide an improved measure of the performance metric of the SDN; applying the identified sequence of adaptations to the SDN by modifying the logical arrangement for use by the control component in subsequent communication via the SDN.
