摘要
软件定义网络(SDN)技术引入分组传送网(PTN)形成软件定义分组传送网(SPTN)技术,大幅提高了网络资源利用效率,提升了网络自动化运管能力。本文设计并实现了一种控制转发管理严格分离、普适性高、可靠性强的基于SDN的分组传送网体系架构,对比了SDN引入前后网络的组织架构及各层功能的变化。结果表明,该架构适用于有线无线混合接入、可靠性高、扩展性强的专网建设。
SPTN technology is formed by introducing Software Defined Network(SDN)technology into the Packet Transport Network(PTN),which can significantly improve the efficiency of network resources allocation and the automation level of operation.a SDN based packet transport network architecture with strict control&forwarding separation,high reliability and universality is designed and implemented.By comparing the architecture and functions of different layers before and after the introduction of SDN,this architecture shows a good suitability for those private networks with high reliability,good scalability and wired&wireless hybrid access requirement.
