In methods and apparatus for controlling a communications network supporting a Layer 3 service, data characterizing activity of the network both in Layer 3 and in at least one Layer below Layer 3 is collected. The collected data are processed to determine that a reconfiguration of the at least one Layer below Layer 3 is favourable, and to determine a favoured reconfiguration of the at least one Layer below Layer 3. Implementation of the favoured reconfiguration is initiated. The Layer 3 service may be a packet data service, such as Internet Protocol service, and the layers below Layer 3 may include an optical transport layer which is reconfigured based on processing of data collected from both the optical transport layer and the packet data layer. Rapid reconfiguration of the optical transport layer according to data collected from both the packet data layer and the optical transport layer reduces over-provisioning of the network needed to meet difficult-to-predict traffic patterns and loss of revenue due to inability to serve traffic with the current network configuration. A Fuzzy Logic control algorithm is described.
