宽带用户数量的增加和接入网相应的快速扩张给提高其能源效率带来了更大的压力，以降低其运营成本和碳足迹。核心是无源光网络（pon），它们是当今领先的宽带技术之一。虽然它们被认为是有线接入技术中最节能的，但其功耗仍然相当高，预计在未来几年内还会增加。因此，针对集中式pon提出了许多节能框架。在本文中，我们首次提出了一种新的PON节能框架，该框架是基于分散的。提出的框架不仅旨在提供更好的网络性能，同时节约能源，而且还支持通过利用边缘到边缘通信将雾计算与pon集成在一起的新型云布局。因此，该框架旨在通过解决以下三个主要挑战来满足下一代接入网的需求：节约能源，实现高网络性能，支持雾计算。
The increasing numbers of broadband users and the corresponding rapid expansion of access networks have been putting more pressure on improving their energy efficiency to reduce both their operating costs and carbon footprint. At the center are passive optical networks (PONs), with them being one of the leading broadband technologies of today. Although they are considered to be the most energy-efficient among wired access technologies, their power consumption is still considerably high and is expected to increase over the next few years. As a result, many energy conservation frameworks have been proposed for PONs that are all centralized-based. In this paper, we propose a novel PON energy-conservation framework that is, for the first time, decentralized-based. Not only does the proposed framework aim to provide better network performance while conserving energy, but it also supports novel cloudlet placements for integrating fog computing with PONs by utilizing edge-to-edge communications. The framework is therefore designed to meet the requirements of next-generation access networks by addressing three main challenges; conserving energy, achieving high network performance, and supporting fog computing.
