Abstract: A link detection technology. In a link detection method, when a target event occurs on paths, in a plurality of paths, whose quantity exceeds a preset quantity, whether the paths on which the target event occurs share a bottleneck link is detected, and congestion control is performed. It can be learned that in the technical solution provided in the embodiments of this application, the target event is a trigger, and shared bottleneck detection is performed after the quantity of the paths on which the target event occurs exceeds the preset quantity. This implements purposeful link detection, reduces system overheads, and brings a fast convergence speed.
