PID-OTN城域网组网应用及策略分析

Application and Analysis of PID-OTN Metropolitan Area Network

全业务综合承载需求极大推动了OTN技术的发展,采用基于PID的下一代OTN技术能打造一张容量大、调度灵活、安全性高的承载网络。文章主要介绍下一代波分PID的特性、原理、组网和设计原则,同时介绍PID和普通OTN波分、SDH应用的对比,进而探讨PID的组网运用。

The full service integrated load demand has greatly promoted the development of OTN technology.Using the next generation of OTN technology based on PID can create a bearer network with large capacity,flexible scheduling,high security.In this paper,we introduce the characteristics,principle,networking and design principles of PID of the next generation wavelength division.At the same time,we introduce the comparison between PID and OTN wave and SDH,and then discuss the application of PID.
