The surging numbers of wireless devices and the accompanying exponential growth of user traffic have led edge and fog computing to become essential components in future access networks. By bringing more processing toward the edge of the network, they enable the realization of various demanding applications while supporting numerous resource-constrained devices. Their integration with passive optical networks and their huge offered bandwidth has therefore attracted much research interest. In this article, we review these computing concepts and examine key considerations for their integration with long-reach optical access networks when the employed upstream bandwidth allocation is either centralized or decentralized.

支持下一代光接入网络中绿雾集成的集中式与分散式带宽分配

无线设备数量的激增以及随之而来的用户流量呈指数级增长，使得边缘计算和雾计算成为未来接入网络的重要组成部分。通过向网络边缘提供更多处理能力，它们可以实现各种要求苛刻的应用程序，同时支持众多资源受限的设备。因此，它们与无源光网络的集成及其巨大的提供带宽引起了很多研究兴趣。在本文中，我们回顾了这些计算概念，并检查了当采用的上行带宽分配是集中式还是分散式时，它们与长距离光接入网络集成的关键考虑因素。
