摘要
操作、管理和维护(OA＆M)信息的传输和处理是智能光网络的关键技术之一.文章首先对比光传送网络(OTN)中OA＆M需求,分析了智能光网络中OA＆M需求的变化.然后,针对OA＆M传输机制、处理复杂度和带宽占用3个方面,讨论了OA＆M系统在智能光网络中实现的难点,比较了现有的处理手段.在此基础上,提出了结合多种消息传输方式,分层、分域处理实现OA＆M系统的思想.最后,按照这种思想,设计了一种适用于智能光网络的OA＆M原型系统.
The transmission and process of OA&M(Operation, Administration & Maintenance) information is one of important technologies for intelligent optical network (ION). This paper firstly analyses the OA&M requirements in ION, in comparison with these requirements in OTN. Then, focusing on three key issues (transmission techniques, process complexity and bandwidth occupation), we discussed the difficulties in OA&M system implementation. Today's solutions are compared. Based on this analysis, guidelines to implement OA&M system is presented, including multi-technology transmission, multi-layer process and multi-domain process. Finally, the prototype OA&M system is designed.
