Simplified Echo-State-Network Based Services Awareness for High-Speed Passive Optical Network

Abstract

With the challenge from services diversity grows greatly, the service-oriented supporting ability is required to current high-speed passive optical network (PON). Aimed to enhance the quality of service (QoS) brought by diversified-services, this paper proposes an Simplified Echo State Network (SESN) Based Services Awareness scheme in High-Speed PON (Passive Optical Network). In this proposed scheme, the ring topology is adopted in the reservoir of SESN to reduce the complexity of original Echo State Network, and system dynamics equation is introduced to keep the accuracy of SESN. According to the network architecture of 10G-EPON, a SESN Master is running in the OLT and a number of SESN Agents work in ONUs. The SESN Master plays the main function of service-awareness from the total view of various kinds services in 10G-EPON system, by fully SESN training. Then, the reservoir information of well-trained SESN in OLT will be broadcasted to all ONUs and those SESN Agents working in ONUs are allowed to conducts independent service-awareness function. Thus, resources allocation and transport policy are both determined just only in ONUs. Simulation results show that the proposed mechanism is able to better supporting ability for multiple services.
