高速铁路宽带通信网络管理系统管理模式研究

摘要

To get reliable and real-time network management,a special network management schema for high-speed railway broadband communication networks is proposed.Firstly,the structure of high-speed railway broadband communication networks based on TD-LTE (time division-long term evolution) and the traditional network management schemas are analyzed,and it is pointed out that the limited wireless train-ground communication bandwidth is the biggest difficulty,then,to conquer this difficulty,a hybrid centralized-distributed network management schema is proposed.Finally,the efficiency of this schema is evaluated and the reliability and instantaneity are validated.%为了保证高速铁路宽带通信网络管理的可靠性和实效性,依据网络的规模、结构、管理接口、支持业务等特点,提出了一种新型的管理模式.系统分析了基于TD-LTE (time division-long term evolution)无线通信技术的高速铁路宽带通信网络的结构特点,指出了有限的车地无线通信带宽是高铁宽带通信网络管理系统要克服的重大难点；针对高速铁路宽带通信网络的这个难点,提出了一种集中式/分布式相结合的混合管理模式,并对该管理模式进行了性能评估,验证了该设计的可靠性和实效性.
