FSAN作为下一代无源光网络的第一阶段，在带宽要求较高的视频应用的驱动下，通过对当前GPON网络进行升级，增加用户带宽。为了降低升级成本，NGA1符合标准化的GPON和已部署的光配电网。本文从mac层带宽分配的角度对五种候选NGA1架构进行了研究，包括分析了用户应用的流量特征以及将它们映射到合适的传输容器的标准。我们进行了大量的仿真来研究和比较五种候选NGA1架构的性能。
Driven by bandwidth-demanding video applications, next-generation access stage 1, proposed by FSAN as the first stage of next-generation passive optical networks, increases the subscriber bandwidth by upgrading the current GPON network. To reduce the upgrading cost, NGA1 conforms to the standardized GPON and the deployed optical distribution network. This article presents the investigation of five candidate NGA1 architectures from the perspective of the MAC-layer bandwidth allocation including the analysis of the traffic characteristics of the subscribers' applications and the criteria in mapping them into proper transmission containers. Extensive simulations were conducted to investigate and compare the performances of the five candidate NGA1 architectures.
