Abstract
The present invention relates to a transmission method of the failure information of a virtual private line service transmission underlying network transmission network. When some transmission network link fails, a corresponding transmission side node and a reception side node of the link can sense the failure information of the link. The transmission side node switches off a corresponding upstream transmission link after sensing the failure information, so that a transmission end user device corresponding to the link can sense the link failure information of a transmission network. After sensing the link failure information, the reception side node generates and sends out messages with the link failure information to a receiving end user device. The receiving end user device analyzes the messages and senses the failure information of the transmission network. The present invention can make a user device sense the failure of network links in time and can ensure normal link use, and the present invention can be widely used in the network communication field.
