摘要
回顾了智能光网络的发展历程,并根据其多域异构化的发展趋势,分析和比较了现有典型光网络架构的特点和性能,进而综合其各自优点,提出了基于PCE和域间连接控制的多域异构光网络管控架构PIONEER以及面向未来可灵活配置、扩展和升级的软件定义光网络(SDON)架构。
The feature and performance of the representative optical network architectures were reviewed,and a novel PIONEER architecture that combines their advantages was proposed.Finally,programmable,scalable and upgradable software defined optical network (SDON) architectures were proposed for future optical networks.
