Embodiment Construction
[0046] Below in conjunction with accompanying drawing, technical scheme of the present invention will be further described:
[0047] A certain set-top box needs to pass through multi-level router devices and ports to obtain program source data. When playing different live programs, the router devices and ports passed through will also be different. There are as many as thousands of business bearing devices for a single operator and provincial company. , each device basically has more than 100 ports, and the number of combined links is as many as hundreds of thousands. When the live video played by a certain set-top box fails, the traditional method requires the operation and maintenance personnel to Log in to each level of equipment to check the uplink equipment and ports from the set-top box to the program source, confirm the specific link information of the channel played by the set-top box, and then manually check the device performance status, network status, service status...

The invention provides an automatic fault positioning method for an IPTV service live broadcast link, and a system thereof. The automatic fault positioning method comprises the following steps: S1, establishing a full-path topological structure from a set top box to a program source in an IPTV service; S2, collecting data of each device in the full-path topological structure; S3, obtaining a full-path topological data table according to the data of each device and the full-path topological structure; S4, calculating a video MOS value; S5, calculating a linear relationship between the equipmentdata and the video MOS value, and establishing a fault logic judgment knowledge base; and S6, positioning a fault point according to the full-path topological data table and the fault logic judgmentknowledge base, and obtaining a fault analysis result. The system comprises a data acquisition module, a data input and output module, a data storage module, a data processing module and a data display module. The automatic fault positioning method and the system thereof can automatically position the fault node, analyze the fault reason, improve the fault positioning efficiency and reduce the operation and maintenance cost.
Description
technical field [0001] The invention relates to a method and system for automatically locating fault equipment used in IPTV live broadcast services, and belongs to the technical field of network fault locating. Background technique [0002] The IPTV service can well adapt to the rapid development trend of today's network, fully and effectively utilize network resources, and provide users with interactive services including digital TV. Due to the high real-time requirements of IPTV services, large network traffic, and many factors affecting quality, it is difficult to accurately and timely find faults in IPTV services. IPTV services need to go through multi-level network equipment and chains from user terminals to program video sources. If a certain device, device port, or link in the link is abnormal, the quality of the video played by the user will be degraded or the video cannot be played at all, which will seriously affect the user perception of IPTV services. [0003] I...
