摘要
从运营商的角度分析Pe-OTN所必需的关键技术,特别是基于信元的统一交叉技术和对于以太网功能和MPLS-TP功能的选择考虑,提出MPLS-TP是更加适合未来传送网架构和业务发展的分组功能。同时针对Pe-OTN在运营商的宽带业务、大客户业务、移动回传和IP层Bypass等部署应用场景进行了需求研究和应用分析,提出了Pe-OTN部署时需要考虑的问题。
The key functionality of packet-enhanced OTN for telecom operators has been analyzed. Especially, MPLS-TP is proposed as the proper solution for packet-enhanced function in packet-enhanced OTN other than Ethernet. The application scenarios of packet-enhanced OTN deployed in broadband access service, leased-line service, mobile backhaul and IP layer bypass are also particularly researched.
