摘要
基于对OTN(光传送网络)技术发展方向的分析,指出SDN(软件定义网络)技术会直接或间接影响OTN未来五大发展方向中的三项,具体体现在软件定义传送平面、软件定义控制平面、IP与光跨层协同融合和光网络资源虚拟化四大方面。研究表明,OTN的SDN化将是超100Gbit/s时代的重要发展趋势。
On the basis of the analysis of the five development trends of Optical Transport Networks (OTN),this paper points out that the Software Defined Network (SDN)technology will have direct or indirect impacts on three of them,specifically em-bodied in four aspects:software defined transport plane,software defined control plane,IP and optical cross-layer cooperation and convergence and optical network resource virtualization.Research results show that SDN is an important trend of OTN be-yond 100 Gbit/s.
