统一承载平台的POTN组网方案研究

Research on Construction of Unified-bearing-oriented POTN Transmission Network

在运营商LTE、宽带和专线等多业务发展的格局下,采用PTN负责IP化、多业务接入、OTN负责大容量传送的组网场景在国内各大运营商网络中比较普遍,但此种组网采用设备背靠背设置的方式加重了运营商在机房空间、动力以及后期运维等方面的压力。POTN集合了PTN和OTN的技术优势,有望解决上述难题。分析POTN技术与设备在LTE、宽带和专线承载等方面的多种引入场景,给出相关组网架构与节点设备配置方案,提出宽带场景下业务的保护建议等。

The operator＇s development of multi-service, such as LTE, broadband and leased line, has led to widespread network construction application of PTN responsible for IP- multi- service access and OTN responsible for high- capacity transmission.However, the back-to-back setting of transmission equipment has aggravated operator＇s impression on confined equipment room space, power and later network-operation. POTN has combines the advantages of PTN and OTN, it will open up a new path for the above problems. It analyzes the application scenarios of POTN technology and equipment on LTE, broadband and leased line, proposes related networking architecture and node configuration solution, gives the suggestions on service protection of broadband application.
