Echo-state-network classification based multi-services awareness in high-speed optical passive networks

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.
