Abstract:Aimed to improve the ability of EPON (Ethernet Passive Optical Network) to support multiple services brought by smart power grid, a Hierarchical Echo-State-Network Based Traffic-Awareness Mechanism in EPON system is proposed for energy internet. The proposed mechanism is able to be aware of characteristics of multi-services and to match their requirements with better quality, through the echo-state-network algorithm. Thus, resources allocation optimization of EPON system is enabled by the proposed mechanism through cooperation between OLT and ONUs. Simulation evaluation of this proposed scheme is conducted and takes smart power grid services as typical application. Simulation results show that this proposed approach can greatly improve the supporting ability for multiple services of smart power grid, in terms of packet loss rate and time delay performances.
