Network energy-saving management control system, method and computer readable medium

Abstract

This invention discloses a network energy-saving management system, method, and computer-readable medium. It involves configuring multiple network transmission devices on a network capable of serving multiple user terminals, where each user terminal may have the same or different network path and bandwidth requirements. At least one controller manages the multiple network transmission devices. Furthermore, the controller's network path calculation and management module can calculate multiple feasible network path combinations based on the network path requirements of the multiple user terminals. A network-wide energy consumption simulation module then uses simulation to apply the bandwidth requirements of the multiple user terminals to the primary network paths of these multiple network path combinations, calculating the overall network energy consumption data for each combination. Additionally, the network path calculation and management module can select the network path combination with the lowest energy consumption across the entire network, allowing a network path rule provisioning module to provision or update network path rules for the primary and backup network paths of the multiple user terminals for the multiple network transmission devices.
