中文摘要： 本项目针对高性能光接入网（OAN）的应用需要，提出一种基于异步光分组交换（AOPS）的接入网架构（AOPS-OAN），研究该接入网的关键技术。AOPS-OAN采用上行业务在线异步光分组交换、下行业务组播结构，将空分光交换矩阵与光纤延时线组相结合，基于分组重传算法和循环光纤延时线，构成全光冲突解决机制。提出适用于AOPS的分组包分级光码字标签处理方法及实现方案。在已有的AOPS分布式控制单节点实验系统的基础上，研制AOPS-OAN三节点示范实验平台，开展基于分级光码字标签的下行组播实验。针对AOPS-OAN网络应用实际需要，提出局端集中式、光编码实时监控方案，可实现对光纤链路的监控。

英文摘要： As the application requirement for the high performance optical access network, a novel architecture of the asynchronous optical packet switching based optical access network (AOPS-OAN) is proposed and the key technologies in the AOPS-OAN are investigated. The AOPS-OAN employs the optical packet switching in uplink and the multicast sending in down link. A packet retransmission algorithm and a recycling-fiber-delay-line (Rec-FDL) based collision resolution mechanism are proposed to resolve the contentions for the asynchronous burst optical packets, by using of the spatial matrix of the optical switches and Rec-FDL. The multistage optical code label (MOCL) scheme is presented for AOPS-OAN. Based on the AOPS experiment system for one node of APOS in the lab, a three-nodes AOPS-OAN experiment demonstration platform will be set up, on which a downlink multicast experiment based on MOCL will be done. A novel centralized optical coding monitoring scheme for the optical fiber link of AOPS-OAN is given and analyzed.
