传输网络范式正朝着以IP融合为目标的下一代网络发展，同时架构和技术正在多样化。包括超高清电视（超过33 M像素）在内的视频技术不断进步，未来的通信网络将以视频为中心。当前IP技术的低效率，特别是IP路由器的能量消耗和吞吐量限制，将成为紧迫的问题。利用光的全部力量将解决这些问题，并刺激未来以视频为中心的网络的创建。光层技术的扩展和与新的传输协议的协调将是至关重要的;分层光路技术和光路/路径交换将发挥关键作用。介绍了这些领域的最新技术进展。
The transport network paradigm is moving toward next-generation networks that aim at IP convergence, while architectures and technologies are diversifying. Video technologies including ultrahigh-definition TV (more than 33 M pixels) continue to advance, and future communication networks will become video-centric. The inefficiencies of current IP technologies, in particular, the energy consumption and throughput limitations of IP routers, will become pressing problems. Harnessing the full power of light will resolve these problems and spur the creation of future video-centric networks. Extension of optical layer technologies and coordination with new transport protocols will be critical; hierarchical optical path technologies and optical circuit/path switching will play key roles. Recent technical advances in these fields are presented.
