The present invention discloses a faulty link detection method, apparatus, node, and system, and belongs to the field of internet protocol television technologies. The method includes: receiving statistical data that is reported by all nodes every preset quantity of packets that carry a program clock reference value, where all the nodes collect statistical data starting from a unified program clock reference value; acquiring, according to the statistical data, the quantity of packets lost between an upstream node and a downstream node among all the nodes; and determining a faulty link according to the quantity of packets lost between the upstream node and the downstream node. The faulty link detection apparatus provided in the embodiments of the present invention acquires statistical data collected at a unified reference time by different network nodes, and obtains, through comparison, the accurate quantity of packets lost between an upstream node and a downstream node, so as to determine a faulty link, thereby effectively ensuring that an IPTV service operator locates a network fault quickly and effectively. |
