摘　　要：分析了城域光网络中接入环和汇聚环之间现有的互联方式及存在的不足,提出了一种新颖的接入环和汇聚环互联的双归属保护方案,分析了该方案的优缺点,给出了该方案的网络拓扑连接、详细的工作原理、双归属APS协议包格式和双归属APS方案的实现框图。In this paper, a current usual scheme and its shortage are analyzed firstly. This scheme is used in in- terconnection of access ring and convergence ring in metropolitan area optical network. On account of this shortage, a novel scheme named dual-homing protection is put forward, which can be used in the interconnec- tion above. Then the merit and demerit of the scheme are also analyzed. After this, a series of research re- sults of the new scheme are given in sequence, including network topological link, detailed working princi- ple, dual-homing APS protocol packet format and dual-homing APS imt3lementation hlne.lc cliaovn,-,,
