摘　　要：PWE3仿真机制的PTN技术继承了MSTP、增强型以太网和IP/MPLS技术的特性,解决了传输技术对数据业务处理能力不足造成带宽浪费严重和路由技术对长距业务处理能力欠缺的问题.首先,PTN技术与MSTP、增强型以太网和IP/MPLS技术的对比,得出PTN技术完全满足实际需求.然后,进行了基于PTN技术的大型本地城域承载网组网和基站回传、固定接入并重的全业务承载网设计.最后,对PTN的关键技术进行了相应设计:包括时间同步设计、3层VPN进化设计、双归保护设计和故障处理设计.PWE3 simulation mechanism of the PTN technology has inherited the characteristics of MSTP, en-hanced Ethernet and IP/MPLS Technology, which solves the problem that the transmission technology is not enough to deal with the ability of data traffic and the lack of routing technology for long distance service. It is concluded that PTN technology meets the needs of the actual demand by comparing PTN technology with MSTP, enhanced Ethernet and IP/MPLS Technology. Based on the technology of PTN large local metro bearing network networking and base station, fixed access pay equal attention to the whole business of bearing network is designed. Finally, the key technologies of PTN are designed, including the time synchronization design, the 3 layer VPN evolutionary design, the double protection design and the fault treatment design.
