A Fully Distributed 10G-EPON-based Converged Fixed–Mobile Networking Transport Infrastructure for Next Generation Broadband Access

Abstract

This work proposes and devises a self-healing hybrid tree/ring-based 10G-EPON architecture that enables the support of a converged PON-4G LTE access networking transport infrastructure to seamlessly backhaul both mobile and wireline business and residential services. The salient feature of the proposed architecture is that it supports a fully distributed control plane that enables intercommunication among the access nodes (optical network units - ONUs) as well as signaling, scheduling algorithms, and fault detection and recovery mechanisms. The distributed control plane enables each and every ONU to independently detect, manage, and recover most of the networking failure scenarios. This paper outlines and addresses the key technical requirements and differences between a PON-based converged architecture that utilizes a typically centralized architecture as the wireless segment of the hybrid architecture (e.g., Wi-Fi) versus one which utilizes a fully distributed architecture (e.g., 4G LTE). Physical layer performance simulations for the proposed architecture are also presented that show error free performance for the scalable architecture.
