DOCSIS3.1物理层新功能分析与应用研究

DOCSIS3.1标准逐步从标准制定走向规模化部署阶段，而网络性能的优化和网络的主动维护功能还有很大的提升空间，本文重点介绍了可变bit-loading的Profile管理功能，并针对Profile管理出现的一些问题，提出了一种新的单播Profile管理方法；同时介绍了DOCSIS3.1PNM运维功能，并分析了新功能面临的挑战以及走向智能运维的转型方向。

Research on New DOCSIS3.1 PHY Functions and Application

DOCSIS3.1 standard is going toward large-scale deployment phase after standard-setting, research and development, but the network performance optimization and network proactive maintenance function still have much room for improvement, the paper focuses on the Profile management function based on variable bit-loading, and then presents a novel unicast Profile management method. At the same time the paper introduce the DOCSIS3.1 PNM functions and analyze the transition to intelligence operations & maintenance and the major challenges.
