Abstract: To meet diverse business needs, both architecture on demand (AoD) nodes and multi-core fibers (MCF) based
software-defined multi-dimensional optical networks will enable customizable network services. Aiming at the problem
of management and control for multi-dimensional network resources, the architecture of software-defined mul-
ti-dimensional optical networks was introduced firstly. Then, the enabling technologies to support the implementation of
software-defined multi-dimensional optical networks were presented. Finally, the development direction of soft-
ware-defined intelligent multi-dimensional optical networks was proposed and analyzed.
Key words: software-defined optical network, multi-dimensional optical network, intelligent control and management,
architecture on demand node, multi-core fiber
1 引言
光纤通信技术由于其传输带宽大、抗干扰性强和
信号衰减小等诸多优点,已成为骨干网中主要的通信传
输媒介。基于光纤通信技术的光网络,必将成为未来信息
社会中的主要网络技术之一。然而,随着 5G
