Abstract
A communication network includes a plurality of network elements—communicating nodes—that are enabled to request the establishment of connections—flows—among each other, and a plurality of network elements—switches ()—that support the routing of the flows. The network further includes elements for intercepting requests for flow establishment, at least one calculation module configured to preselect for each flow a set of possible network paths that are compliant with the flow's performance requirements and/or quality constraints, wherein each path includes a specific set of switches the flow has to traverse, and at least one selection module configured to apply a selection algorithm that analyzes the load of switches that are contained in any network path of the preselected set of network paths for determining a single network path from the preselected set of network paths that is most suitable in terms of energy efficiency.
