The invention discloses a communication network early-warning analysis system based on big data analysis. Through adoption of SOAs, backbone transmission networks are divided into a network control and data collection layer, a platform layer and a management application layer; different levels of backbone transmission networks are managed comprehensively; through system interconnection between SOAs, information transverse sharing and application coordination of the different levels of backbone transmission networks are realized between the same levels and between upper and lower levels of a communication management system; through synthesis of the resume information, machine account information and service utilization information of the communication management system, according to level distribution of communication network resource occupation, the utilization condition of the resources is comprehensively analyzed from various aspects such as optical fiber resources, multiplexing section resources and channel resources; the resource utilization condition data of communication devices and communication optical fibers is stored in real time; through analysis of communication resource occupation of different levels, comprehensive analysis is carried out on existing massive history operation and maintenance data through utilization of a big data technology; and potential hidden dangers possibly existing in the communication network can be predicted in advance.
