Abstract: This application provides a tunnel binding based communication method and a network device. The method includes: transmitting, by a first network device, a service packet to a second network device using a first binding tunnel including a first tunnel and a second tunnel; and when the first tunnel is faulty or transmission quality of the first tunnel does not meet a preset condition, transmitting, by the first network device, a service packet to the second network device using a second binding tunnel including a backup tunnel of the first tunnel and the second tunnel. Therefore, if a tunnel in an original binding tunnel is faulty, a tunnel binding based high-bandwidth service continues to be provided using another binding tunnel constituted by a backup tunnel of the faulty tunnel and a fault-free tunnel. Compared with the prior art, this application can improve high-bandwidth communication reliability and user satisfaction.
