Problems solved by technology
ARQ technology is only a means of compensation, and there are still defects in the equipment. There are two main problems: 1) The hidden dangers of the equipment still exist, and may aggravate as time goes by, eventually causing the packet loss to exceed the maximum threshold; 2) If the packet loss Error correction cannot be performed beyond the maximum threshold, and user perception cannot be improved

The present invention provides a method and device for fault detection of IPTV network equipment, wherein the method includes: determining the service account for data retransmission based on the data retransmission log information and user viewing record information, and determining the service account for data retransmission according to the service account and based on the data retransmission log information , user viewing record information and device information, obtain the index value corresponding to the network device for determining the fault, and determine whether the network device is faulty based on the result of judging whether the index value conforms to the preset fault judgment rule. The method and device of the present invention can effectively solve the current situation that IPTV operators have no effective support means for the jamming problem caused by network packet loss; the investment cost is low, and there is no need to deploy monitoring points on network equipment, only through ARQ logs, resources Hidden dangers of equipment can be discovered and located by associating, converging, and calculating through tree and user viewing records; it can actively discover hidden dangers of network equipment to avoid affecting user perception.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for detecting faults of IPTV network equipment. Background technique [0002] The latest data shows that the number of IPTV users of China's three major operators has exceeded 100 million, and the domestic IPTV business is developing rapidly. According to the survey, freezing is one of the most important factors affecting users' viewing perception, and network packet loss is the main cause of video freezing. In order to improve users' tolerance to network packet loss, IPTV operators often introduce various error control technologies. For the unicast service, the mechanism for packet loss recovery is ARQ (Automatic Repeat Request, automatic repeat request). ARQ technology requires the support of CDN nodes and set-top boxes on the IPTV platform. It means that when packet loss occurs in network transmission, the set-top box can detect packet loss locally...
