PTN与OTN联合组网模式及其关键技术研究
|
摘要
为了适应全网业务IP化趋势,满足传送网多样化接入、大容量传输和业务灵活调度的需求,在分析PTN与OTN技术优势的基础上,提出了一种新的PTN与OTN联合组网模式。介绍了PTN和OTN联合组网的策略,给出了联合组网的模式,并对联合组网中的设备互联互通、全网时间精确同步和组网保护等关键技术进行了研究。
In order to adapt to the tendency of all services in IP, and meet the demands of diversified access,large capacity transmission, and service flexible scheduling in transmission network, on the basis of analyzing the technology advantage of PTN and OTN, this paper puts forward a new joint networking model of PTN and OTN. It introduces the joint networking strategy of PTN and OTN, provides the model of joint networking, discusses the pivotal technologies in the joint networking, such as device interoperability, precise time synchronization, networking protection and so on.
