摘要
简要介绍了PTN/OTN技术、传送网分层结构及PTN+OTN一般组网模式;详细阐述了偏远、普通及发达地区PTN+OTN组网策略。这3种组网策略基本涵盖了各地区本地传送网建设方向,能最大化地满足传送网容量和安全性需求。
It presents PTN/OTN technology, transport network hierarchy and the networking mode of PTN＋OTN. In consideration of the economic development level, three OTN＋PTN networking strategies of local transport networks are presented. Using these networking strategies, the capacity of local transport network can be fulfil ed and the network security can be enhanced.
