Abstract
A faulty link detection method includes receiving statistical data that is reported by all nodes every preset quantity of packets that carry a program clock reference value. All the nodes collect statistical data starting from a unified program clock reference value. The quantity of packets lost between an upstream node and a downstream node among all the nodes is acquired according to the statistical data. A faulty link is determined according to the quantity of packets lost between the upstream node and the downstream node.
