摘 要:目前对配电通信网可靠性的研究主要以网络单元可靠性为基础,从网络单元故障的影响范围、业务流量承载系数、故障时长、故障对运行业务的危害度以及受影响业务的路由恢复预案几个方面,综合研究网络单元故障对通信业务可靠性的影响,针对通信网中特定类型的通信业务,明确影响其可靠运行的关键部件和部件集合,并制定相应的保护预案。通过实例分析,比较了该方法与传统方法的区别和优势,验证了该方法的可行性。At present,the main content of reliability research on distribution communication network is the reliability of network topology based on the reliability of network unit. The impact of network unit failures on the reliability of communication services was comprehensively studied from the aspects of the impact of network unit failures,service flow bearing coefficients,fault durations,hazards of faults to operational services,and route recovery plans for the affected services. For a specific type of communication service in a communication network,the key units and unit sets that affect its reliable were clearly identified,and corresponding protection plans were formulated. Through the case analysis,the differences and advantages between the method used in this paper and the traditional method were compared,and the feasibility of the method was verified.
关 键 词:配电通信网 业务可靠性 故障影响 故障危害度 关键部件
