PTN+OTN传输技术在城域传送网中的应用探讨

Discussion on the Application of PTN+OTN Transmission Technology in Metropolitan Area Transmission Network

在现代社会的发展中,社会各界对IP业务的需求日益增大,传统4G网络时代的承载模式已无法满足实际的发展需求,如SDH难以适应以TDM为内核的城域网的技术需求,这就需要将PTN+OTN传输技术应用到城域传送网中,实现海量数据的高效传送。

In the development of modern society, the demand for IP services is increasing in all walks of life. The bearer mode of the traditional 4G network era can no longer meet the actual development needs. For example, SDH is difficult to adapt to the technical requirements of the metropolitan area network with TDM as the core. It is necessary to apply the PTN+OTN transmission technology to the metropolitan area transmission network to realize efficient transmission of massive data.
