Abstract
Embodiments of the present application disclose a traffic offloading method and apparatus. The method includes: calculating, by a first network node, a first packet loss rate of a first forwarding tunnel in a preset period; when the first packet loss rate is higher than a first preset threshold, reducing a rated bandwidth of the first forwarding tunnel by a first preset bandwidth, so as to obtain a first available bandwidth; and when traffic forwarded over the first forwarding tunnel exceeds the first available bandwidth, offloading excess to-be-forwarded traffic to the second data link for forwarding. Because the first available bandwidth is less than an original available bandwidth of the first forwarding tunnel, the to-be-forwarded traffic exceeds the first available bandwidth at an earlier time, traffic is offloaded by the first network node in advance, and a serious packet loss is less likely to occur before traffic offloading.
