摘要
本文从SDN的概念和总体架构出发,总结了SDN技术的重要特征和引入PTN通信网络的优劣势,并与运营商的业务和网络需求互相结合,提出了在运营商PTN网络中引入SDN技术的场景以及实现的方案,为现有通讯网络迈向未来网络提出了一种新的发展思路。
From the concept and structure of SDN, this paper summarizes the important features of SDN, and the advantages and disadvantages to introduce PTN （Packet Transmit Network）. By combining with operator busi-ness and requirements of service, we put forward a scene and an implementation scheme to build PTN with SDN technology, which provides a new idea for the future network development.
