Abstract: | With the challenge of great growing of services diversity,service-oriented supporting ability is required by current high-speed passive optical network (PON).Aimed at enhancing the quality of service (QoS) brought by diversified-services,this study proposes an echo state network (ESN) based multi-service awareness mechanism in 10-Gigabite ethernet passive optical network (10G-EPON).In the proposed approach,distributed architecture is adopted to realize this ESN based multi-service awareness.According to the network architecture of 10G-EPON,where a main ESN is running in OLT and a number of ESN agents works in ONUs.The main-ESN plays the main function of service-awareness from the total view of various kinds of services in 10G-EPON system,by full ESN training.Then,the reservoir information of well-trained ESN in OLT will be broadcasted to all ONUs and those ESN agents working in ONUs are allowed to conduct independent service-awareness function.Thus,resources allocation and transport policy are both determined only in ONUs.Simulation results show that the proposed mechanism is able to better support the ability of multiple services. |
