摘要
在简要回顾传统性能监测方案的基础上,引入了插入型(Intrusive )和非插入型(Non-intru-sive)在线性能监测的分类方式,着重阐述了基于模拟量监测的非插入型光性能监测方案。
The traditional performance monitoring sche- mes of Optical Transport Network (OTN) is proposed first. Two concepts, intrusive monitoring and non- intrusive monitoring, are introduced. In service perfor- mance monitoring schemes based on optical analog symbol analysis are discussed deliberately.
