摘要
随着移动4G业务不断成熟,5G时代的到来,每天都有大量的信息数据需要从一个地方传送到另一个地方。业务种类需求不断增加,通信网络需求是电信运营商亟待解决的重要问题,现有的信息运输方式SDH、WDM、OTN、PTN都为单一数据传输方式,不能同时满足高速TDM专线、分组交换的全业务传送需求,迫使人们提出了一种新的融合承载信息方案POTN;POTN深度融合分组传送和光传送技术,提供多业务、大容量、长距离的信息承载方式;POTN集成OTN、TDM和分组技术于一身的统一传送平台,根据业务的类型选择最佳的传送方式,减少网元种类。
With the mobile 4G business continues to mature,5G era of arrival,every day a lot of information data needs to be transferred from one place to another place.The existing information transportation methods SDH,WDM,OTN,PTN are single data transmission mode,can not meet the high-speed TDM line at the same time,the group exchange of the whole POTN deep integration of packet transmission and optical transmission technology to provide multi-service,high-capacity,long-distance information bearing the way;POTN integrated OTN,TDM and packet technology in the development of a new,A unified transmission platform,according to the type of business to choose the best way to send,reducing the types of network elements.
