摘　　要：在电信业务不断发展的形势下,PTN凭借自身面向连接、良好的性能管理以及分组交换技术的重要特性,开始出现在电信运营商网络建设的选择中。现阶段,对PTN网络的规划、建设和发展已经成为了电信运营商的一个重要研究方向。本文分析了针对电信运营的应用中,PTN组网设计的一些要点,包括分层和分域架构,传送标签转发的面向连接与分组的统计复用协议、多业务接入和承载等几个重要方面。最后还指出了PTN未来发展的重要方向。In the continuous development of telecom business situation, PTN becomes one of the selections of network construc- tion for telecommunication operators, with the characteristics of connection-oriented performance management and packet switching technology. At present, PTN network planning, construction and development have become an important research direction for tele- corn operators. This paper analyzes some key points of PTN network design in the application of telecom operation, including hierar- chical and subfield architecture, connection-oriented and statistic packet multiplexing protocol of transfer label forwarding, multi-ser- vice accessing and load bearing. It points out the important direction of the future development of PTN.
